Description

[0002] Rubber generally refers to a high-elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under the action of small external force, and can restore to original state after the external force is removed. Rubber can be divided into natural rubber and synthetic rubber. Natural rubber is processed from gum extracted from rubber trees, rubber grass and other plants. Synthetic rubber is made by polymerization of various monomers.
