Predispersed Rubber Chemical Si69-50
Identification:
Chemical Name: Bis[3-(triethoxysilyl)propyl]tetrasulfide
Synonym: Pre-Dispersed Polymer Bound Chemical Si69-50; Rubber Coupling Agent Si69
CAS: 40372-72-3
EIENCS: 254-896-5
Molecular Formula: C18H42O6S4Si2
Properties:Si69 reaction & bonding with highly dispersed filler such as white smoke and other chemical, meanwhile bonding with the rubber, make its produce after vulcanization excellent dynamic and static properties. Significantly reduced the viscosity when mixing; improve the rubber compound of wear resistance and modulus.
Dosage: Mixing with reinforcing agent, 5-20% of the white smoke, 1.0-2.0% of clay and mica.
