Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature and can undergo significant deformation under small external forces. After removing external forces, it can return to its original state. Rubber belongs to completely amorphous polymers, with a low glass transition temperature (T g) and often a large molecular weight, exceeding several hundred thousand.
Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is extracted from plants such as rubber trees and rubber grass and processed into gum; Synthetic rubber is obtained through polymerization reactions of various monomers. Rubber products are widely used in various aspects of industry or daily life.
