Siperox® Organic peroxide

Siperox® BIBP 40%

Siperox® BIBP can be used as a crosslinking agent for rubber and plastics, such as silicone rubber, ethylene-vinyl acetate copolymer (such as EVA foam), chlorinated polyethylene rubber (CPE), ethylene propylene diene rubber (EPDM), chlorosulfonated poly Ethylene, tetrapropylene fluorine rubber (TP-2), saturated hydrogenated nitrile (HNBR). In the case of the same cross-linking effect, the addition amount is about 2/3 of other organic cross-linking agents. There is no irritating odor during operation and in the finished products. It is especially suitable for flexible cord insulation cross-linking and EVA foam products in silicone rubber molding vulcanization chambers, such as rubber sheathed cables for air conditioners, EVA foam toys, etc.

Usage: It can be used by adding rubber material during mixing. When the crosslinking effect is required, the addition amount of 3 parts can completely crosslink the high molecular polymer.
