Antimony Trioxide [ Powder ]

DATA PDF

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 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.

Raw material antimony
Antimony ore

  1. AT3
    Product is selected and procured from all over the world and finished at Moriya plant. It performs stably as flame retardant synergist and corresponds to business continuity planning (BCP), so customers can use it continuously with an easy mind.
     
  2. AT-3CN
    Product is a collaboration between our company and Hsikwanshang Twinkling Star in Hunan, China, worldwide antimony marketer. They produce AT-3CN based on our processing technology and quality management system. We guarantee stable quality as well as AT3.
     
  3. AT-3TL
    Product is made from antimony ore and metal mined in Myanmar and Vietnam and is manufactured in Thailand. It is finished at our Moriya plant and is sold as a non-China product. The impurities lead (Pb) and arsenic (As) is controlled to the standard value of 500ppm or less each, and it is a product with high whiteness.
     
  4. AT-3LT
    Product has bigger particle size and gives high transparency. AT-3LT is mainly used for high gloss ABS and PVC pigment.
