Antimony trioxide is a pure white powder with cubic crystal structure.

Purpose:

It is widely used as flame retardant in PVC, PP, PE, PS, ABS, PU and other plastics. It has high flame retardant efficiency and little influence on the mechanical properties of the base materials (such as fire-proof work and gloves, shell of flame-retardant electronic equipment, fire-retardant carriage, flame-retardant wire and cable, etc.). It is used as filler and flame retardant in rubber industry.
