Catalytic Antimony Trioxide
Antimony trioxide is a kind of white fine powder and the main crystal structure is of cubical shape.
Product Description:
This product used is made from high quality refined antimony by our unique iso-ion refining technique. Its characteristic are: fine size, high whiteness, pure few impurities, pure crysta pattern, high activity, easy to disperse.
Application:
1. Mainly used as polyester catalytic in the synthetic fiber industry. It is the product with high solubility in ethylene glycol and this allows the products to be introduced into the PET reactor as a solution or suspension instead of powder form.
2. used as a fire retardant in the membranes of plastic industry ,the enclosures of electric devices and household electric appliances,such as PVC, PP, PE, PS, ABS and PU, etc..
3. Used as filling, covering agents and retardants for rubber, ceramics, enamels, fabrics and fiber products.
4.Used as catalytic agent in organic synthesis.
