Natural Rubber (NR)

Natural Rubber is made of Rubber latex which collected from Rubber trees, it is a polymer of isoprene with good wear resistance, high elasticity, tensile strength and elongation. It is easy to aging in the air, and become sticky under heating, also easy to expand and dissolve in mineral oil or gasoline. It has good alkali resistance but weaker in strong acid.

Advantages:

Good elasticity, acid and alkali resistance.

Disadvantages:

Weather resistance, oil resistance (can be resistant to vegetable oil).

Application:

The raw material of tape, rubber hose, rubber shoes, and suitable for the production of shock parts, automotive brake oil, ethanol and other liquid with hydroxide used rubber products.
