无味交联剂BIPB 40
无味交联剂泛称BIPB无味架桥剂,可作为氯化聚乙烯、三元乙丙橡胶、EVA乙烯—醋酸乙烯共聚物、硅橡胶、丁晴橡胶等 塑料和橡胶的交联剂, 也可作为 PP 降解剂。在同等交联效果的情况下,操作过程中及制成的制品中刺激性臭味小。
BIPB is a bifunctional peroxide which is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins.

Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the self-accelerating decomposition temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test. The SADT is 80℃.
