High tensile strength & elongation, low heat generation Nature Rubber Valve Seat

 

Basic characteristics of NR

1. Unsaturated rubber, active chemical properties, can carry out addition and cyclization reaction, and sulfur, oxygen and other reactions, easy to react.

2. Non-polar rubber, none oil resistance.

3. Crystalline rubber has self-reinforcing properties and high elasticity.

4. Become glass state under -70 degrees.

5. With good comprehensive performance: high tensile strength, high elongation, low heat generation.

6. Good air permeability and electrical insulation.

8. Anti-aging and returning performance is poor, anti-aging system and vulcanization system and anti-reversion system should be considered when manufacturing products.

9. Use in tires: mainly used for tread of heavy-duty tires, truck tires and light trucks..

 

Certificates obtained:

IATF16949 quality management system, certififies include WRAS, ACS, NSF, KTW, W270, DVGW, EN681, etc for the needs of different countries.
