Antimony - Flame Retardants

Antimony trioxide has been used as a white pigment since ancient times. The pigmentation from antimony oxide in plastics can be controlled and adjusted by the judicious selection of a Sb 2 O 3 grade having a specific particle size. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity.

Antimony Oxide - an overview | ScienceDirect Topics

Burning time and limiting oxygen index depend on plasticizer type and amount. They are not greatly affected by addition of antimony oxide, aluminum trihydrate, or zinc borate. 177, 179, 181, On the other hand, addition of antimony oxide, aluminum trihydrate, or zinc borate in combination with phosphate plasticizers reduces the peak heat of ...

DynaSil™ - Have Freedom In Formulation - Polymer Dynamix
