Almost all the plastic products consumers’ use today have a touch of color in them. Color is not there only for aesthetic purpose, they function as a method to differentiate product’s categories, models and sizes. Because colored plastic is such a common practice, it leads to an assumption that plastic coloring is a simple process. While in reality, the challenge of coloring polymer involves complex science and technical skills.

First and foremost, it is the fundamental of developing a polymer colorant package. Often, the color of a product is customized per producer’s request, from the primary hues to tone, tint and shade. The ratio must be sophisticatedly engineered since the final appearance could be influenced by the polymer structure or the addition of other additives and stabilizers. Furthermore, if the desired color is obtained, there is always a chance other attributes like flame retardants agent, UV stability will be adversely affected. Hence several items are often put into careful consideration.

1. Chances of Chemical Mismatch

The chemistry of the pigment and the chemistry of the polymers may spot incompatibility problem in the mixing process. The fusion procedure includes elevated temperatures combined with aid from mechanical energy input. As a common fact, chemical reactions are facilitated at such intense thermal condition. If the chemical formulation is not prepared well beforehand, it cannot be stopped during the mixing procedure and the result will experience a fault or inferior.

Occasionally, errors may happen during the chemical interaction between lesser-known components hidden behind the core material. For instances, cadmium-free red pigments will likely to cause problem of flexibility loss when mixing with modified-purposed nylon.

2. The Temperature Environment

The thermal stability of the coloring system also carries a science into its process. Often, each constituents have a distinct level of temperature environment in which it can survive, interact with each other and be utilized, or all fail together. In order to optimize the formulation, the temperature was elevated to an excess of 150°C (300°F). At this point, the polymer structure are ready to be processed, but the question is whether the colorant chemistry would survive the heat. What engineers need to ensure then is to select the right pigment for the right polymer at the right heat. A pigment mixed with polycarbonate or polysufone with their high process temperature must have the capability of endure more intense heat. Meanwhile, a pigment chose for polyethylene or polypropylene can be processed on a relatively cooler thermal environment.

3. Differences Made by the Amount of Colorant

The ratio of pigment added into the base polymer could make a significant impact on how the final products present to be, not only in overall appearance but also in the internal quality of the polymer.

An excessive amount of colorant can negatively affect the structure of the base polymer. One of the most noticeable signal is the flexibility loss. In science term, pigment in some case can be considered a type of nano-constituents. The incorporation of pigment into polymer can alter its chemical structure, leading to some of its quality being stolen in the process. There is always an acceptable compatibility level in the amount of colorant mixing, usually a variance of more than 1 -2 % of that amount will cause problem.

4. Different Methods to Color Plastic

There are several manners in which polymers could be colored. They can be manufactured via masterbatch (also called concentrates), in which color pigment is concentrated into a carrier resin prior to injection molding. Other methods include precolored resin (or compounds) via melt blending. Each method has its advantages and disadvantages compared to each other.

The most cost-effective method is to directly mixing pigment powder with plastics. This can only be considered if used in a small quantity or urgent case, since the color is not put into optimal condition to truly incorporate with polymer. The result is that the product cannot achieve ideal color appearance: the color may be faded or unevenly distributed.

The second method is using masterbatch, this ranks as the most frequently-used plastic-coloring method. Masterbatch functions as pigments and additives mixed into a frame of polymer resin on high heat. This remains as the most economical approach to add color into plastic in mass, with quick turnaround time and high chance to achieve color specification.

Cube blend is the method of blending dry masterbatch with natural polymer. When there is no supplied metering equipment, cube blends helps engineers the control of how the exact final output will present. In this method, the polymer does not experience high heat and can preserve its original properties.

In such case with the necessity of high let down ratio, engineers often consider the use of precolored resin. This method is credited on its ease-of –use and quick performance rate. As pigments are directly polymerized into a resin frame, they can maintain consistency and overall properties and avoid certain error in the mixture process. Obviously, they do not offer the economical value like masterbatch.

5.  The Quality and Weight of Carrier Resin

Lastly, even the quality of the carrier resin has to be taken into consideration. Ensuring the compatibility of the carrier resin and base resin is just the first step, the mismatch in molecular weight between constituent can create a difference.

In addition, the base condition can have influence on the appearance of color. The same color used in nylon will appear lighter than it will in acrylic, even with the same tone and hue. The external of environment after the final products cool down from heat also have a certain percentage of effect on how it will be presented.

On 27/2/2019, Hanoi hosted the summit between two of the world’s most infamous leaders: President Donald Trump of the USA and president Kim Jong Un of North Korea. Even though the visit of President Kim, as normally, was shrouded by mystery, there is one image that takes the world by storm.

This green train is entirely bullet-proofing, it is Kim Jong Un’s favorite means of transportation and carries the symbol of the North Korea leader.

In light of this bizarre event, this article would address a fact only military specialists may know: bulletproof vest and glass, as we often see in movies and television nowadays, all have plastic as one of the chief components.

The history of bullet-proof vest

Throughout the medieval and feudal eras, protection suit for combat soldiers were associated with the famous term “amour”. For centuries, soldier stormed into the battlefield with mail armor, a costume consists of iron, steel or brass chains. In many regions like China or Japan, people developed scale armor, with materials taken from animal scale, bone or hone to make leather and metal clad.

The arrival of the World War I had triggered severe changes and revolution in the use of weapon. Gunfire erupted the battles and experiments were called to invent a modern armor which can challenge of force of gun.  Reinforced steel plate would also limit soldier’s movement and impede their arms. Several models of gunfire-proof were introduced but in the end, none really made a significant effect.

The plastic revolution of the 1940s marked a turning point in the history of weapon technology. Military scientists invented the first models of the modern bullet-proof vest, made of ballistic nylon fused with plates of fiber-glass, titanium, steel and ceramic. They bore the strength of steel and the resilience, lightweight of plastic. Due to such convenience, the vests were widely used by law enforcers and military personnel.

In 1965, Du Pont chemist Stephanie Kwolek invented the Kevlar, the most common bullet-proof suit until today. Instead of ballistic nylon, Kwolek turned to poly-para-phenylene terephthalamide, a type of polymer that can be transformed into aramid fiber and sewed into cloth. Since then, Kevlar suit has been the standard and traditional bullet-proof vest.

Nowadays, bullet-proof vest is made from a sheet of advanced plastic polymer, with layers of Kevlar or other material like Spectra Shield, coated and bounded by resins. In extreme situation, metal plates can be inserted between the fabric to protect the most vulnerable part such as chest or upper back.

Bullet-proof glass: A sandwich of glass and plastic

A normal piece of glass would shatter if hit by a bullet simply because glass is inflexible. It cannot bend or absorb heat and energy. The science behind bullet-proof glass is simple to demonstrate: they are made from layers of glasses sandwiched with interlayers of plastic. The layers are often designed to maintain their thin width, but they are still twice heavier than an ordinary glass panel of the same size.

When the bullet hit the glass, its energy will be spread and absorbed through the layers of glasses and plastic and quickly dries out. At this point, the glass layers will break apart, but it’s the plastic panel that hold them together. Therefore, when attacked by gunfire, bullet-proof glass will crack but not shatter, since only the glass panes are broken but the plastic remains.

Plastic is, by all means, the devil we befriend. For all the call of environmentalists about banning plastic use for goods, it remains as the truth that humans can’t separate their daily life from plastic. They are parts of our cars, our homes. They are what keep our food fresh overnight and most importantly, they are the basic material used in hospital and medical care. We have often been warned of being drown by the ocean of plastic we left behind. But the opposite is also true, without plastic, the human civilization may collapse just as quickly.

Today, we will look at five of the most innovative inventions made from plastic.

1. Artificial heart

The use of artificial heart is considered one of the break-through innovation in the medical industry. A plastic heart maintain the lives of patients during the time they wait for a proper heart transplant, or simple extend their lives in the case no donor heart is available. According to the the SynCardia, a person with a TAH (Total Artificial Heart) comprises of pulsatile, ventricles and valves like a human’s heart. It is biocompatible and can help the patients enjoy an active life to 5 years before they could find a donor heart.

2. Spacesuit

A spacesuit is the shield of an astronauts, their protection against the hostile cosmo environment. Spacesuit helps them breath, perform normal activity in a zero-gravity environment and move among space dust to collect planet material samples.

Due to these requirement, spacesuit has to be flexible, strong and anti-UV radiation. This suit is comprised of several layers of plastic, they are resilient enough to endure extreme conditions, heat, forces while the plastic material is still light enough to allow movement.

3. Plastic wheelchair

There is an estimate of hundred million disabled people in the developing countries cannot afford for themselves a wheelchair. Life is hard for the poor, and it is made almost impossible for those suffering both disability and poverty. Mechanical engineer and inventor Don Schoendorfer thought of a solution: a low-cost, substainable wheelchair that can be produced in mass to support thousands of people at a time.

The wheelchair is a combination of available supplies, a plastic lawn, a steel frame and bike-tires. Such a simple design, but thanks to it thousands of disables are able to move again.

In 2001, Schoendorfer founded Free Wheelchair Mission. His nonprofit organization has delivered mobility to people in 80 developing countries at zero price.

4. Seabin Project

In 2015, two Australian surfers came up with an idea to combat the plastic waste piling up in their oceanland. The Seabin is a floating rubbish bin that can be located in the marinas, docks water area. The inside of the bin circled along the force of windblow and tide. Water is sucked through the catch bag inside while rubbish remained trapped in the bag, ready to be expose. The bin can even collect a percentage of oil and liquid waste through its fin.

The Australian government had issued order to optimize this project in several habors and docks in the country.

5. Lego houses

With the rising housing crisis in Colombia together with the mountain of plastic landfill left on ports, Colombian startup Conceptos Plásticos has invented a new model of construction: a real-life Lego houses for homeless people. The house is totally made of recycled plastic bricks, it can be built and decluttered within days.

Due to the resilence of plastic, these bricks can hold again earthquakes, fire and lightnings. They are also considered as an optimal solution for temperary residence of natural disaster. If there is a need to move location or to redesign the house, residents can remove the bricks, store them on their car and rebuild them again.

In 2015, 42 families in Colombia has registered as owner of these mobile Lego house.

The Difference between Extrusion Blow Molding and Injection Molding

There are not one, but several methods can be used to form plastic bottle and containers, among these the most common terms are Extrusion Blow Molding and Injection Molding. Both are processes to produce plastic parts, both requires the input of melted polymer into a metal mold, but they serve two different markets.

Extrusion Blow Molding

Extrusion Blow Molding (EBM) is the procedure of extruding (or blowing) melted plastic into a mold. Extrusion blow molding follows six fixed steps. As the mold is put in a released state, a mass of melted, unformed plastic is extruded into a open mold. As the mold closes, tightening a grip on the plastic tube, compressed air is bumped into the tube. The layer of plastic is then inflated until it perfectly cling to the metal mold. In the final stages, the newly-formed plastic bottle is trimmed and released from the mold, ready for the next step of delivery. Types of plastic used in blow molding are: High Density Polyethylene (HDPE), Polypropylene (PP), Polyethylene Terephthalate (PET), Polycarbonate (PC), Polyester and Urethane.

Injection Molding

Injection molding provides a similar concept with a different mechanism. Plastic granules are transferred through a barrel where it will be heated and metled. The melted plastic mass will then be forced into a mold. There was no air pressure, no inflation technique, plastic is injected until it loads the metal mold. In the final step, the mold opens and removes the object, already cooled and solidfied. Types of plastic commonly used in injection molding are: ABS, Polypropylene (PP), Polycarbonate (PC), PVC, Nylon.

Two different techniques, two different purposes

The core difference between the two technique of blow molding and injection molding is the finished forms of the products. Blow molding is utilized to produce hollow parts like bottles, barrel, containers. Manufacturers rely on blow molding when they need to produce complex shapes, something that speaks of value, identity, branding. However, it also equates that in extrusion blow molding.

On the other hand, injection molding is considered for the manufacture of more solid parts: bottle caps, pocket combs, automotive dashboard, packaging, wire spools. The technique serves a completely different market of supply to blow molding. While it is not optimal to use injection molding to produce complicated part, the process has a high performance rate. It can deliver a significant volume of quality, solid parts with great accuracy at a high rate of speed.

Addition Polymers: The addition polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds, e.g., the formation of polythene from ethene and polypropene from propene  However, the addition polymers formed by the polymerisation of a single monomeric species are known as homopolymer, e.g., polythene  The polymers made by addition polymerisation from two different monomers are termed as copolymers, e.g., Buna-S, Buna-N, etc

Condensation Polymers: The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units  In these polymerisation reactions, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc. take place  The examples examples are terylene terylene (dacron), (dacron), nylon 6, 6, nylon 6, etc  For e.g., nylon 6, 6 is formed by the condensation of hexamethylene diamine with adipic acid  It is also possible, with three functional groups (or two different monomers at least one of which is tri-functional), to have long linkage sequences in two (or three) dimensions and such polymers are distinguished as cross linked polymers.

Polymers classification Based on Molecular Forces

The mechanical properties of polymersare governed by intermolecular forces, e.g., van der Waals forces and hydrogen bonds, present in the polymer, these forces also bind the polymer chains  Under this category, the polymers are classified into the following groups on the basis of magnitude magnitude of intermolecular intermolecular forces present present in them, they are: Elastomers, Fibers, Liquid resins, Plastics (which includes Thermoplastic and thermosetting plastic)

Elastomers

These are rubber – like solids with elastic properties  In these elastomeric polymers, the polymer chains are random coiled structure, they are held together by the weakest intermolecular forces , so they are highly amorphous polymers  These weak binding binding forces permit the polymer polymer to be stretched stretched  A few ‘crosslinks’ are introduced in between the chains, which help the polymer to retract to its original position after the force is released as in vulcanised rubber  The examples are buna-S, buna-N, neoprene, etc

Fibers

If drawn into long filament like material whose length is at least 100 times its diameter, polymers are said to have been converted into ‘fibre’  Polymeric chains are straight chain polymers, they are held together by the strong intermolecular forces like hydrogen bonding, these strong forces also lead to close packing packing of chains and thus impart crystalline nature  Fibres are the thread forming solids which possess high tensile strength and high modulus  Examples are polyamides (nylon 6, 6), polyesters (terylene), etc.

Liquid Resins

Polymers used as adhesives, potting compound sealants, etc. in a liquid form are described liquid resins, examples are epoxy adhesives and polysulphide sealants.

Plastics

A polymer is shaped into hard and tough utility articles by the application of heat and pressure; it is used as a ‘plastic’  The intermolecular force between polymeric chains are intermediate between elastomers and fibers, so they are partially crystalline.

Typical examples are polystyrene, PVC and polymethyl methacrylate. They are two types: Thermoplastic and Thermosetting plastic.

Thermoplastic Polymers

Some polymers soften on heating and can be converted into any shape that they can retain on cooling  The process of heating, reshaping and retaining the same on cooling can be repeated several times, such polymers, that soften on heating and stiffen on cooling, are termed ‘thermoplastics’  These are the linear or slightly slightly branched branched long chain molecules molecules capable of repeatedly softening on heating and hardening on cooling  These polymers possess intermolecular forces of attraction intermediate between elastomers and fibres  Polyethylene, PVC, nylon and sealing wax are examples of thermoplastic polymers.

Thermosetting Polymers

Some polymers, on the other hand, undergo some chemical change on heating and convert themselves into an infusible mass  They are like the yolk of egg, which on heating sets into a mass, and, once set, cannot be reshaped. Such polymers, that become infusible and insoluble insoluble mass on heating, heating, are called ‘thermosetting” ‘thermosetting” polymers polymers.  These polymers are cross linked or heavily branched molecules, which on heating undergo extensive cross linking in moulds and again become infusible  These cannot be reused. Some common examples are bakelite, urea-formaldelyde resins, etc.

They connected these colloids to the surface of marginally bigger, permeable silica nanoparticles loaded down with anti-infection sedate atoms. Ordinarily, this gold-silica complex discharges shining, red bright light. Yet, when the lysozyme units experience microscopic organisms, a solid fascination for cell dividers tears the gold nanoclusters from their silica accomplices—an activity that at the same time turns off fluorescence and discharges the anti-infection load.

Mixing tests uncovered the gold-based nanofillers coordinated completely into polymer composites and displayed negligible filtering amid preliminaries with E. coli. Khashab properties these positive polymer connections to the sharp uncovered edges of gold groups on the silica circles. The scientists tried their idea by contrasting X-beam dental plates and without the shrewd polymer covering. The two examples yielded a similar high-determination pictures of teeth and bone structure. Be that as it may, just the covered plate empowered fast visual evaluation of bacterial tainting, basically by lighting up the gadget with an UV-light and searching for shading change. Effective arrival of the antibacterial operator likewise radically diminished biofilm development.
