Antimony Trioxide

Synonyms: Antimony (III) oxide; Antimony white; biantimony trioxide; flowers of antimony; Antimonius Oxide; Antimony Peroxide; Antimony Sesquioxide; Antimony oxide; diantimony trioxide; senarmontite; exitelite; weisspiessglanz;

Antimony trioxide is produced in many forms such as:
High Tint: (micron sizes from 0.2 to 1.8) CAS No.1309-64-4
Low tint: (micron sizes from 2.0 to 13.0) CAS No.1309-64-4
Granulated with DOP (master-batch)
Granulated with DIDP (master-batch)
Wetted:, with selected elements such as chlorinated paraffin, DOP, etc to make it, Dust free
Low lead (lead below 0.04%)
PET Catalyst grade, has high reactivity and high solubility in ethylene glycol

Uses of Antimony Trioxide:
Flame retardant in Plastic Resins, Rubber, Adhesives, Paint, Fiberglass, paper, glass, Porcelain, Textile, Oil field additives, cars and aircraft seat covers, Hydroseeding, Intumescents.

It is an ideal synergist with good physical properties and translucency.

The main different chemical families of flame retardants are:

(1) Inorganic Chemicals (Antimony, aluminum and tin compounds),
(2) Bromine and chlorine based flame retardants,
(3) phosphorous based and
(4) Nitrogen (melamine) based flame retardants.

It is proved (times and times) that Antimony trioxide is the best quality and economical flame retardant.
