Properties

During the sulfidation, the coupling speed of S69C tetra sulfur alkyl group is nearly the same as curing behavior speed in sulfur cross-linking, which improves the heat generation of rubber and crackle extensibility. 4 S atoms can promote sulfurization

It can improve the stuffing strengtheningcharacteristics and increase abrasive resistance of rubber. As the rubber agent-curing ingredient and promoting agent.

It can increase their abrasive resistance, reduce hysteresis quality and hydroscopicity, improve their mechanical performance and splicing performance and increase their ageing performance, modulus and bending life-span.

Applications

Silane USi-S69C is an e organic silane coupling agent that used in in below industries:

It can be successfully used in plastic industry;

It is fit for the perduren system with the strengthening agent of white carbon black, glass fiber, talcum powder, mica, clay, etc.

It is fit for the types of rubber: NR, NBR, SBR, IR, BR, EPDM, etc.

It can be used in the products in dynamic and statistic working condition, such as tyre, hose, rubber roll, cable insulation and coating material, shoe, mechanical foundry, etc.
