[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can return to its original shape after the external force is removed. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry and life.
