Why Choose Polyurethanes?

Aug 29, 2018

This section looks at the main properties of polyurethanes and explains their widespread use in so many applications. Not only are polyurethanes affordable and safe, they are also sustainable materials offering added comfort and protection to our everyday lives. The sustainability section outlines how polyurethanes preserve the Earth’s natural resources by reducing the need for energy. It also summarises what the polyurethanes industry is doing to protect our planet’s resources for future generations, and shows the recycling and energy recovery options available at the end of a polyurethane product's lifetime. The comfort section describes how polyurethanes make our lives more comfortable, from the relaxation... Read More

Thermoplastic vs. Thermoset Resins

Aug 24, 2018

Thermoplastic polymer resins are extremely common, and we come in contact with thermoplastic resins constantly. Thermoplastic resins are most commonly unreinforced, meaning, the resin is formed into shapes and have no reinforcement providing strength. Examples of common thermoplastic resins used today, and products manufactured by them include: PET - Water and soda bottles Polypropylene - Packaging containers Polycarbonate - Safety glass lenses PBT - Children's toys Vinyl - Window frames Polyethylene - Grocery bags PVC - Piping PEI - Airplane armrests Nylon - Footwear Many thermoplastic products use short discontinuous fibers as a reinforcement. Most commonly fiberglass, but carbon fiber too. This increases the mechanical properties and is technically considered a fiber... Read More

Learn the Basics of the Plastic Resin Polypropylene

Aug 21, 2018

Polypropylene is a type of thermoplastic polymer resin. It is a part of both the average household and is in commercial and industrial applications. The chemical designation is C3H6. One of the benefits of using this type of plastic is that it can be useful in numerous applications including as a structural plastic or as a fiber-type plastic. History The history of polypropylene began in 1954 when a German chemist named Karl Rehn and an Italian chemist named Giulio Natta first polymerized it. This led to a large commercial production of the product that began just three years later. Natta synthesized the first... Read More

Fantastic plastics: Research collaboration could reshape injection molding

Aug 15, 2018

UNIVERSITY PARK, Pa. — As Ralph Colby peers at the microscope image in front of him, he thinks he can make them out — "shish kebabs," as polymer scientists call them. Nobody knows for sure what they are, but these shapes that appear at seemingly unpredictable times when certain plastics cool have a big impact on the overall properties of plastics. It's not a big deal when a plastic fork breaks, but if a bearing cage on an airplane were to break, it could put people in danger. Colby has partnered with two other Penn State researchers to get a... Read More

Plastic Injection Molding Can Be Eco-Friendlier Than You Think

Aug 08, 2018

Once plastics were invented in early 1900’s, using plastics and making plastic products has become an inseparable part of how humankind in expanding the boundaries of creativity. Plastics have revolutionized product manufacturing by replacing other materials. Plastics are now everywhere and will be a part of our lives forever. Plastic injection molding is playing a big part in this plastic revolution. Injection molded parts are in virtually any product you buy from stores. Looking at the vast amount of plastic parts that are assembled together to make products you might think what can be done to make them eco-friendlier. How... Read More

Spin Casting Process

Aug 01, 2018

Introduction: Also known as centrifugal rubber mold casting (CRMC), the main features of spin casting process is the use of rubber mold and employing centrifugal force for casting. During the solidification process the mold spins on it central axis till the metal solidifies in the mold. Spin casting is a widely used non-expendable process, for casting products that have excellent details and surface finish. Process: For spin casting, first strong patterns are made out of silicon rubber or investment cast wax, that are designed using rapid prototyping system or other pattern making methods. The pattern are places in a uncured silicon mold to... Read More

How the Tweel Airless Tire Works

Jul 23, 2018

For more than 100 years, vehicles have been rolling along on cushions of air encased in rubber. The pneumatic tire has served drivers and passengers well on road and off, but a new design by Michelin could change all that - the Tweel Airless Tire. In this article, we'll look at what the Tweel Airless Tire is, why you would use it in place of traditional tires, some of the problems that may occur with a Tweel Airless Tire and where you might see the Tweel Airless Tire in the future. Michelin first announced the Tweel in 2005. The name is a combination... Read More

Wheel Chair Tire Information

Jul 16, 2018

The selection and condition of each wheel chair tire is pivotal to your riding comfort and ease of movement. Expect tires to require regular attention and occasional replacement, as part of your wheelchair's ongoing maintenance needs. Things to consider when choosing tires include manufacturer requirements, body weight, ease of installation, replacement availability, style and size. Typical types of wheel chair tires include the following. Pneumatic Tires Pneumatic tires are the most popular type of wheelchair tire because they are light weight and provide good traction. This results in a a more comfortable ride and better shock absorption than other tires.... Read More

What is Polyurethane?

Jun 27, 2018

We use polyurethanes in one form or another every day – at home, in our offices and cars, for sport and leisure activities and on holiday. Polyurethanes are versatile, modern and safe. They are used in a wide variety of applications to create all manner of consumer and industrial products that play a crucial role in making our lives more convenient, comfortable and environmentally friendly. Polyurethane is a plastic material, which exists in various forms. It can be tailored to be either rigid or flexible, and is the material of choice for a broad range of end-user applications such as: insulation... Read More

Manufacturing: Plastic Molding & Forming

Jun 18, 2018

Injection Molding Injection molding is a versatile process for forming thermoplastic and thermoset materials into molded products of intricate shapes, at high production rates and with good dimensional accuracy. The process involves the injection, under high pressure, of a metered quantity of heated and plasticized material into a relatively cool mold--in which the plastic material solidifies. Resin pellets are fed through a heated screw and barrel under high pressure. The liquefied material moves through a runner system and into the mold. The cavity of the mold determines the external shape of the product while the core shapes the interior. When... Read More
