Raw materials / Resources / Recycling
raw materials
Antimony trioxide is a white-colored powder that is, like tin and bismuth, a byproduct of lead smelting.
Chemical Products Business
Main products（Chemical Products）
We manufacture and sell zinc oxide as well as lead oxide and zinc sulfate, which we are the only company to manufacture in Japan. Zinc oxide is used as a vulcanizing accelerator to strengthen rubber products. Lead oxide meanwhile is used as a vinyl chloride stabilizer, in paints and in electronic materials such as ceramic condensers. Zinc sulfate is used as a raw material in fabrics, paper, animal feed and health food products.
