Polymer alloys What are polymers? Polymers are materials made of long, repeating chains of molecules. The materials have distinctive properties, banking on the kind of molecules being bonded and how they are bonded. Some polymers are lean and stretch, like rubber and polyester, while others are thick and tough, like epoxies and glass. However, the …
What are Thermoplastics and Thermosetting Plastics? We have heard this question so many times. So really What are Thermoplastics and Thermosetting Plastics? Thermosets are a group of polymers when melted undergo an irreversible reaction chemically and cannot be remelted for reuse. Once these materials are cured in the moulding process, they form a very high …

Thermoplastic Materials BASIC INTRODUCTION: The word “plastics” refers to products produced from polymers by various processes. Processes such as injection moulding, extrusion, blow moulding, vacuum moulding, thermoforming, injection blow moulding, rotational moulding, etc. A provided polymer can be used in many other types of goods, such as Adhesives, coatings, fabrics, elastomers, etc. In the plastics …

When combined, they form another material that has properties different from the individual components. Components are made of two parts: a fiber and a matrix. Fibers …
Basics of Polymers An introduction to polymers Wherever we look around ourselves, we see polymers. The tires of the cars that we travel in, the rubber tips on your earphones, the material of your jackets, everything around us is made of polymers. So much that you should realise that you are looking at polymers even …
Thermosetting Plastic Thermosetting Plastic Polymers and Resins are commonly referred to as Thermosets. They are a form of polymer that is hardened by the process of curing soft liquids, viscous liquid prepolymer, and resin. Curing hardens the substance to such an extent that it becomes irreversible. It is performed by inducing heat and radiation through …

There are five major polymer blend types: Thermoplastic-thermoplastic blends Thermoplastic-rubber blends Thermoplastic-thermosetting blends Rubber-thermosetting blends Polymer filler blends As a simple and cost-effective method of producing polymeric materials with …
