Rubber is a highly elastic polymer material with reversible deformation.

It is elastic at indoor temperature and can produce large deformation under the action of a small external force.It can return to its original state after the removal of external force.

There are many types of rubber including EPDM, Neoprene Rubber, Viton, Natural Rubber, Nitrile Rubber, Butyl Rubber,Timprene, Synthetic Rubber, etc.
