Solid Silane Crosile® 69C

Crosile® 69C it is a mixture of Crosile® 69C silane coupling agent and carbon black with the same function as Crosile® 69C but easier to operate.

Crosile® 69 can improve the physical and mechanical properties of rubber and greatly strengthen tensile strenth, antitearing strenth, abrasion resistance, reduce the permanent deformation and viscosity of gross rubber, improve process property.

The suitable polymer include NR,IP,SBR,BR,NBR,EPDM, etc.

Applications

During the sulfidation, the coupling speed of Crosile® 69C 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

Crosile® 69C can improve the stuffing strengtheningcharacteristics and increase abrasive resistance of rubber. As the rubber agent-curing ingredient and promoting agent.

Crosile® 69C 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.
