Product Detail
Properties

HP-669C

Composition:Mixture of Bis-[3-(triethoxysilyl)-propyl]-tetrasulfide and Carbon Black 

Equivalent Product Name: Z-6945(Dowcorning)

Physical Properties:It’s black small pellet with light odor of alcohol.

Specifications:

Application Range:

•HP-669C is a kind of multifunctional poly sulfur-silane coupling agent that has been used successfully in the rubber industry.

•HP-669C 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 to be used as rubber additive---vulcanizing agent and activator in polymers such as NR, IR, SBR, BR, NBR and EPDM.

•In the process of vulcanization, the crosslinking rate of poly sulfur alkyl is the same as deoxidizing rate of sulfur, so it act to resist deoxidizing of vulcanization of sulfur, and then improve dynamic bending properties such as heat build up and cracks expansion .The sulfur atoms can act as activator for vulcanization.

•In dynamic and static conditions, It is used for producing these rubber products: tire, hose, rubber roll, belting, cable, shoe and mechanical founding products. It can improve abrasive resistance, cutting resistance and pressure resistance, reduce hysteresis loss and hygroscopicity, improve mechanical and adhesive properties, and increase thermal ageing performance, modulus and flex life.

•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.
