Antimony Trioxide (Sb2O3) CAS1309-64-4 White Powder Industrial Grade PVC Flame Retardant

Product Description

Antimony trioxide

Antimony trioxide(Diantimony trioxide) is a Inorganic compound with chemical formula Sb2O3. The Natural product, known as antimony white, is a white crystalline powder with a melting point of 655 ℃ and a boiling point of 1550 ℃.

Antimony trioxide is a kind of high dispersed superfine granular material, made from antimony trioxide powder of which surface is treated through chemical method that make the powder slightly moisturizes to avoid any fine powder suspending in the air and bringing out harm to human body, meanwhile the antimony trioxide can resist fire and enhance the plastic features.
