Antimony Trioxide（AT3,AT-3ᶜᴺ,AT-3TL）

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 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.

1. AT3
