Applications: Applied in the production of foam product which has fine and uniform cell structure, and is odorless, pollution-free and nondiscolouring. Also applied in the production of elastomer under room pressure or bulging pressure (such as styrene-butadiene rubber (SBR), neoprene, natural ruber), and of thermoplastic products (such as polyvinyl chloride(PVC), polyethylene(PE), polystyrene(PS), ABS engineering plastics), or used together with the blends of resin and rubber. It has great ascendancy for manufacturing wire and cable with its good insulatibity. In some conditions, it can react as foaming agent while also reac as crosslinking agent in the curing reaction. It can work with other foaming agents.
