The most common type of rubber is natural rubber, and natural rubber is also commonly used.

Natural rubber NR-(Natural Rubber) is an isoprene polymer made from rubber latex collected from rubber trees. It has good wear resistance, high elasticity, breaking strength and elongation. It is easy to age, heat and adhere in the air, expand and melt in mineral oil or gasoline, and is resistant to alkali but not strong acid.

Advantages: good toughness and corrosion resistance.
