Application:
It is used as chemical raw material in rubber、plastic、paint、medicine、printing ink、cable、electron、cosmetics. It can be the activating agent and heat transfer thermal conduction in producing the sole of rubber and plastic. It also help the decomposition of AC when finished products are
made by using AC foaming agent.
