Crosile®69C it is a mixture of Si-69 silane coupling agent and carbon black with the same function as Si-69 but easier to operate.
It 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.
Solid Silane Bis-[-(triethoxysilyl)-propyl]-tetrasulfide Carbon Black for Tire Industry
Type
Crosile®69C
Chemical 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.
Synonyms
The mixture of Bis-[3-(triethoxysilyl)-propyl]-tetrasulfide(50%) and Carbon Black (50%)
Di-(3- ethoxy silane propyl)--tetrasulfide and carbon black mixture
