Thermoplastics are polymers, which soften (becomes pliable and plastic) and melt when heated. In the melted conditions thermoplastics may be formed by various methods (injection…

Elastomers are polymers possessing high elasticity – may be reversibly stretched at high degree. Elastomers consists of long lightly cross-linked molecules. Common elastomers are: Polyisoprene…

Glass transition is the transition of an amorphous substance from its soft and pliable state to a hard and brittle (glassy) state. Glass transition vs….

Polymer is a substance (natural or synthetic), molecules of which consist of numerous small repeated chemical units (monomers) linked to each other in a regular…

There are three general groups of polymer materials: Elastomers Thermoplastics Thermosets Elastomers Elastomers are polymers possessing high elasticity – may be reversibly stretched at high…

Vulcanization of rubber is a process of improvement of the rubber elasticity and strength by heating it in the presence of sulfur, which results in…

Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular…

A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous…

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a…

Thermoplastic materials are those materials that are made of polymers linked by intermolecular interactions or van der Waals forces, forming linear or branched structures. A…
