What is poly sulfur silane coupling agent?

poly sulfur silane coupling agent. SI-69 can be used in the vulcanized rubber system with fillers such as silica, fiberglass, talc powder, mica powder and clay as reinforcing agent. It can improve the reinforcing properties of fillers and rubber abrasive resistance properties.It is suitable

What is Si-69 coupling agent?

Si-69 is a functional rubber additive that reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds.

What is silane coupling agent?

The silane coupling agent improves the surface functionality of the bamboo fibers and enables the fibers to bond chemically with the rubber matrix. The treatment provides better wetting and dispersion of fibers in the rubber matrix. Navin Chand, Mohammed Fahim, in Tribology of Natural Fiber Polymer Composites (Second Edition), 2021

What is Si 69 used for?

SI-69 is used successfully in the rubber industry as a dual functional organic poly sulfur silane coupling agent. SI-69 can be used in the vulcanized rubber system with fillers such as silica, fiberglass, talc powder, mica powder and clay as reinforcing agent. It can improve the

What is sulfur-silane coupling agent?

Add sulfur-silane coupling agent in the industry of rubber tire, it’s not only debase the risk of puncture as temperature too high running on the high speed road or long time, but also reduce roll resistance of tire, then reduce the consume of gasoline, the emissions quantity of CO₂ as to accord the environmental protection of carbon reduction.

How does Si 69® react with white fillers?

Applications and propertiesSi 69® reacts with silanol groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. This imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and o
