CAS No. 1309-64-4 Flame Retardant Antimony Trioxide Sb2o3

Antimony Trioxide



Description: is made by antimony metal as raw material. It is white powder with wide range of applications.
More than 80% of antimony trioxide is used as a flame retardant additive for various type of plastics, rubbers, and fiber.

Antimony trioxide also used for polyester polymerization catalysts, variable resistors, decolorizing and fining of optical lenses, and as pigments. 

Name: Antimony Trioxide / ATO
Formulation: Sb2O3
Processing: It is made by antimony metal as raw material through reaction furnace after high  temperature and cool down processing.

Antimony Trioxide Dust Free

Description: Antimony trioxide dust free grade, a kind of product with special chemical treatment on the surface base on antimony trioxide powder.

Dust free technique make the powder in slight wet condition.
So, it can not only avoid human inhalation and touch possibility, but also can achieve the high efficiencyof flame retardancy and plasticing.

It is very good protection for downstream factories worker and friendly to environment.

Specification:

Main Material	Antimony Trioxide (99.5%/ 99.8% 99.9%)
Wetting agent	EG, DOP, DIDP, DINP, CP
Contents	Antimony Trioxide: 99.5%-97%(Weight), Wetting agent: 3%-5%(Weight)

Package:
1. Standard packing: 25KG draft bag with plastic bag, shrink-wrapped and pallettized per 1 metric ton,
2. Big packing: 500KG bag or 1000KG sack. shrink-wrapped and pallettized per packing.
3. Tailor requests

Antimony Trioxide MASTERBATCH

Description: Antimony masterbatch is one kind of mixed product with polymer resin, antimony trioxide powder.
It is granule type with better flowablity and dispersion in compound process.

Ingredient:

Main materials	Antimony Trioxide (99.5%-99.8%)
Carriers:	PE, PP, PS, PA6/66, PBT, EVA, PVC, EMA, etc.

Appliations:
Antimony trioxide masterbatch can entirely replace antimony trioxide powder in plastics, rubbers flame retadant compounding process.
It is mainly used into Polyolefin, PVC, Engineering plastics, rubbers as FR synergist.
