Physical Properties:
Silane coupling agent Crosile – 69 is a pale yellow transparent liquid.It has light odor of ethyl alcohol .
Silane Si69 can be soluble easily in ethyl alcohol, acetone, benzene, toluene etc .It is insoluble in water.
Synonyms:
Silane coupling agent Si 69,TESPT,Polysulfide Tetrasulfide
Specification:
Sulfur silane coupling agent is a kind of multi functional silane coupling agent.
Crosile-69 can be used in rubber industry because silanol group can combine with white carbon black fillers
Sulfur silane imparts many properties ,such as greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic .
And it could improve physical and mechanical properties of vulcanization when mix with the polymer.
tetrsulfide sulfur could reduce the viscosity and improve the processability when rubber productsprocess .
Crosile – 69 reacts with silanol groups of white fillers and then vulcanization under formation of covalent chemical bonds.
Silane coupling agent is especially suitable to improve the reinforcing properties of fillers ,because it contains hydroxyl groups in all unsaturated polymers and having double bonds or their blends.
ECOPOWER APPLICATION
Crosile 69 is successfully applied in the rubber industry,such as Low rolling resistance tyre, mechanical rubber products, Shoe Sole,rice roller
Also include Silica, talc powder, mica powder and clay when combination .
In addition silane coupling agent can be applied in polymers, such as NR, IR, SBR, BR, NBR and EPDM.
