[0002] Rubber generally refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after removing the external forces. Rubber can be divided into natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grasses; synthetic rubber is made by polymerizing various monomers.
