Catalytic Antimony Trioxide Sb₂O₃-99.90

Antimony trioxide. It acts as a polyester catalytic agent in the synthetic fiber industry and in organic synthesis as well. It also acts as a flame retardant in the membranes of plastic industry, the enclosures of electric devices and household electric appliances, such as PVC, PP, PE, PS, ABS, PU, etc. It is used as a covering agent and as filler for rubber, fabrics, and fiber products. It appears as a white fine powder and the main crystal structure is of cubical shape. It has high solubility in ethylene glycol due to which it is allowed to be introduced into the PET reactor as a solution or suspension instead of powder form. It is also used in synthetic resin and papers. It uses high quality antimony trioxide as the raw material and is grained by polymerization.
