Usage: Used for the production of rubber products such as steel radial tire, bias tire, conveyor belt, rubber tube and tape, rubber shoes, emulsion glove etc.
Characteristic and function:
1.It is high active and with even granularity. It can dispersing well among other materials and improve the vulcanization, enhance the cross-link density of rubber and make the vulcanization more completely.
2. It can better the viscosity of rubber and increase the adhesion with steel wire and code fibber.
3.It’s good dynamic performance make rubber products with little deformation, low heat generation, high ability of anti-wearing and anti-aging.
4.It’s main property index can satisfy the national standard ,chemical industry industry and ASTM.
