Elastomers are usually thermosets (requiring vulcanization) but may also be thermoplastic (see thermoplastic elastomer). ... As a result of this extreme flexibility, elastomers can reversibly extend from 5–700%, depending on the specific material.

Are elastomers thermosetting?

Elastomers are defined by their very large deformability with essentially complete recoverability. ... These elastomers are frequently included in the category of “thermosets,” which are polymers with a network structure that is generated or “set” by thermally induced chemical cross-linking reactions.

What is difference between thermoset and elastomer?

Thermosetting plastics are hard, glassy polymer materials that are permanently cross-linked three-dimensionally via chemical main valence bonds. ... Elastomers are dimensionally stable plastics that are, however, elastically mouldable and have a glass transition point that is below the application temperature.
