Antimony Oxide Families, Products and Uses.
It is proved (times and times) that Antimony trioxide is the best quality and economical flame retardant. Other Antimony products:
Antimony Pentaoxide or Antimony Pent oxide)
Antimony Potassium Tartrate
Potassium Pyro antimonate
Sodium Antimonate (for glass industry)
25 kg bags (40 bags per pallet)
1000 kg and 500 kg super-sacks (in this size it becomes hazardous chemical by DOT and UN)
In Pre-weighed EVA bags of: 1 kg, 3.3. kg, 10 kg. (this bags is dropped with the bags into the batch)
Pneumatic track purity and impurities of standard 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.
