Product Detail
Properties

HP-669B

Composition:A mixture of Bis-[3-(triethoxysilyl)-propyl]-tetrasulfide and EPDM

Physical Properties:Light yellow rubber pellet.

Specifications:

Application:

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

•HP-669B 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 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 four 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.
