Description

Technical Field

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (Tg) and a large molecular weight, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum 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.
