Antimony Trioxide [Powder]｜PRODUCT

Antimony Trioxide is widely used as flame retardant synergist for various plastics.

Flammability standard for industrial and consumer products such as plastics, rubber, textile, etc. becomes stringent yearly. Along with the tightening, flame retarding of new material and expansion of the application needs for flame retardants are sophisticated and diversified. We line up four grades of antimony trioxides depend on the production and finishing sites.

Hsikwangshang Twinkling Star

Raw material antimony
Antimony ore

AT3 is finished at Moriya plant and its quality management is highly reputed.
AT-3^CN is co-developed product with Hsikwanshang Twinkling Star in Hunan, China, worldwide antimony marketer. They produce AT-3^CN based on our processing technology and quality management system. We guarantee the stable quality as well as AT3.
AT-3TL is product finished in Thailand. Raw material antimony ore is mined in Myanmar. We market it as non-China product. We control less than 500ppm each of lead (Pb) and arsenic (As) as impurity and it has higher whiteness.
AT-3LT has bigger particle size and gives high transparency. AT-3LT is mainly used for high gloss ABS and PVC pigment.
