Hits: 729 img

DCP is dicumyl peroxide, also known as vulcanizing agent DCP. It is a strong oxidant. It can be used as initiator of monomer polymerization and is often used as vulcanizing agent, crosslinking agent, curing agent, flame retardant additive and so on.

It is mainly used as vulcanizing agent of natural rubber and synthetic rubber, initiator of polymerization reaction, and crosslinking agent of polyethylene resin. Crosslinked polyethylene is used as cable insulation material, which not only has excellent insulation and processing properties, but also can improve its heat resistance. Vulcanizing agent dcp2 is used for 100 parts of polyethylene 4 copies. The vulcanizing agent DCP can make the ethylene vinyl acetate copolymer (foam) foam form a fine and uniform foamed hole, at the same time, improve the heat resistance and weatherability of the product. In addition, it is also used as a curing crosslinking agent for unsaturated polyester.

Vulcanizing agent bis-25, i.e. 2,5-dimethyl-2,5-di (tert butyl peroxy) hexane, referred to as AD. Light yellow oily liquid. There is a special smell. The relative molecular weight is 290.45. Relative density 0.8650. Melting point: 8 ℃. Boiling point 55 ~ 57 ℃ (0.9333) × 103Pa)。 Decomposition temperature 140 ~ 150 ℃. Refractive index: 1.4230, 1.4185 (28 ℃). Insoluble in water. Flash point 41 ℃. Toxic and explosive. Vulcanizing agent for silicone rubber, polyurethane rubber, ethylene propylene rubber and other rubber;, It can be used as crosslinking agent for polyethylene and curing agent for unsaturated polyester. The tensile strength and hardness of the products are high.

Vulcanizing agent, used for silicone rubber, polyurethane rubber, ethylene propylene rubber and other rubber, can improve the tensile strength and hardness of products, while the elongation and compression deformation are low, and the smell after vulcanization is the smallest among alkyl peroxides. Its usage can be added to the compound during mixing. Crosslinking agent, which can be used for polyethylene; Unsaturated polyester curing agent. The tensile strength and hardness of the products are high
