Vulcanizing agents (crosslinking agents)
Chemical name: di-tert-butylperoxydiisopropylbenzene Molecular formula: C6H4[C(CH3)2OOC(CH3)3]2 Molecular weight: 338 CAS NO: 025155-25-3 or 2212-81-9 Chemical Structure: Properties: insoluble in water; partially soluble in organic solvents such as ethanol, ether, benzene, carbon tetrachloride. The theoretical active oxygen content is 9.45%, the decomposition temperature is 182 ° C (half-life 1 minute), 118-120 ° C (half-life 10 hours), self-accelerating decomposition temperature: (SADT) 80 ° C, activation energy: 36.1 kcal / mol. Uses: This product can be used as a crosslinking agent for plastics and rubbers such as chlorinated polyethylene, EPDM rubber, ethylene-vinyl acetate copolymer, silicone rubber, nitrile rubber, fluororubber, etc., and also as a PP degradation agent. In the case of the same cross-linking effect, the amount added is about 2/3 of the DCP, and the irritating odor in the operation process and the finished product is small. Packing, storage and transportation: PE plastic bags in inner packaging, net weight 5kg per bag; outer carton packaging, net weight 20kg per carton. Storage temperature is normal temperature, this product is not easy to deteriorate. Avoid exposure and severe vibration during transportation. Avoid heat, and it is strictly forbidden to store and transport with strong acid and reducing agent. |
