Elastomer manufactured by a chemical process as distinguished from natural rubber obtained from trees.

Man-made polymer.

Made by polymerizing hydrocarbons; see Neoprene.

Synthetic rubber is any type of artificially made polymer material which acts as an elastomer. An elastomer is a material with the mechanical (or material) property that it can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation. Synthetic rubber serves as a substitute for natural rubber in many cases, especially when improved material properties are needed.
