- In the past, “rubber” was used to describe materials that occurred naturally in nature; and “elastomer” was used for materials that were produced synthetically ... silicone elastomers, for example. An elastomer is a polymer that shows elastic properties. Since the terms rubber-like and elastomeric mean almost the same thing, the terms “rubber” and “elastomer” are often used interchangeably today to describe silicone elastomers.

Thermoplastic elastomer It was not until the 1950s, when thermoplastic polyurethane polymers became available, that TPE became a commercial reality. During the 1960s styrene block copolymer became available, and in the 1970s a wide range of TPEs came on the scene.hermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of cross-linking bond in their structures.
