Commonly used polyolefin and rubber Vulcanization crosslinker, is also the free radicals initiator of the production of polymer. Mainly as various olefin polymer crosslinker such as polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), chlorinated polyvinyl chloride (CEP), ethylene-propylene-diene terpolymer (EPDM), ethylene-propylene rubber binary (EPR), silica rubber, polyurethane rubber.
Also as unsaturated polyester resin curing agent. After crosslinked polymer of the physical nature has some improved. Products thermo resistance, chemical resistance, pressure durability, crack resistance and mechanical strength can increase.
Also available separately as monomer polymerization initiator. As a good quality widely used in building decoration materials, polyolefin, foam, crosslinked PE, insulation wire and cable, shoes, flame retardant paint, plastic foam and various other plastics and rubber products.
