有機 過酸化物 are not only suitable for crosslinking rubber elastomers, but also for crosslinking thermoplastic plastics. in industry, they are mainly used for crosslinking polyethylene and its copolymers. Polyethylene products crosslinked with peroxides not only maintain excellent insulation, but also have high heat resistance and mechanical and physical properties. in industry% resistance and external externals. substitute insulation, but also have high heat resistance and mechanical and physical properties. . ... . . 従って, over 90% の the insulating plastics used for wires and cables are styrene and its copolymers crosslinked with peroxide. At present, the most widely used type of organic peroxide crosslinking agent is dicumyl peroxide (DCP), which has high crosslinking efficiency, low volatility, and good transparency and heat resistance of products. しかし, due to the decomposition of DCP during the crosslinking process, which produces harmful acetophenone to human health, there is an environmental pollution problem during use and operation, and the-cross-linked products have residual odor.
BIBP cross-linking agent is a high-end and new environmentally friendly cross-linking agent. The application field and performance of the product are basically equivalent to DCP. This product has high cross-linking efficiency, good heat resistance, low-temperature flexibility, and pressure deformation resistance of the product. BIPB crosslinking agent can be used as a crosslinking agent for rubber and plastics such as polyethylene (PE), ethylene vinyl acetate copolymer (such as EVA foam), chlorinated polyethylene rubber (CPE), ethylene propylene diene monomer (EPDM), chlorosulfonated polyethylene, tetrafluoroethylene rubber (TP-2), saturated hydrogenated nitrile rubber (HNBR), silicone rubber, etc. Under the same crosslinking effect, the amount of BIPB crosslinking agent added is about 2/3 of dicumyl peroxide (DCP). There is no irritating odor during the operation and in the finished products. Especially suitable for silicone rubber molded vulcanization indoor flexible wire insulation cross-linking and EVA foam products, such as rubber sheathed cables for air conditioning, EVA foam toys, etc.
biggest advantage of BIBP as a crosslinking agent compared to DCP is that during crosslinking, DCP will produce phenylethyl ketones with an unpleasant odor. The odor will remain in the-cross-linked product, and BIBP cross-linking agent does not have this disadvantage. Therefore, it is known as "odorless DCP".
