| Catalytic Antimony Trioxide |
 |
Antimony trioxide is a white fine powder and the main crystal structure is of cubical shape.
Product Description: This product used high quality antimony trioxide as the raw material and is grained by polymerization. It not only keeps special property of high quality antimony trioxide but also has no influence on the producing environment and workers' health because there is no dust in operation.
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. It is widely 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,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.
Packing: Packed in 25 kilograms multiwall paper bags, 40 bags |
