Rubber introduction

Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can be restored to its original state after removal of external force. Rubber belongs to completely amorphous polymer, its glass transition temperature (T g) is low, molecular weight is often large, more than hundreds of thousands.
Rubber is divided into natural rubber and synthetic rubber two kinds. Natural rubber is made from gum extracted from rubber tree, rubber grass and other plants. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.
