Antimony Trioxide Masterbatch
（Environmental Friendly）
Product Description
Antimony Trioxide Masterbatch is made of Antimony Trioxide powder, nucleating agent, dispersing agent etc. Granules are extruded by the twin-screw after effective mix.ATO content can reach 90% in the granule.
Applications
Antimony Trioxide masterbatch as the most important inorganic flame retardant synergist is not only used in the engineering plastics such as electronic industries, electrical appliances, lamps and lanterns etc., but also widely used in wire, cable, pipe and sheet. The usage method and adding amount is equal to powder(90% content). Carrier can be adjusted according to customer’s demand.

Frequently Asked Questions
What is ATO Masterbatch?
ATO Masterbatch is an antimony-trioxide flame-retardant synergist supplied pre-dispersed in a PE/EVA carrier. Its bromine content is ~90% active.
What is the CAS number and formula of ATO Masterbatch?
ATO Masterbatch is a formulated product, composed of Sb2O3 ~90% in PE/EVA.
What is ATO Masterbatch used for?
ATO Masterbatch is used for flame-retardant plastic compounds, films and cables where dust-free synergist dosing is preferred.
How does ATO Masterbatch work?
The antimony trioxide acts as a synergist for halogenated flame retardants; delivering it as a masterbatch gives clean, dust-free, uniform dispersion and safer handling than powder.
Which materials is ATO Masterbatch compatible with?
Plastics, films, cables and compounds that use halogenated flame retardants.
Is ATO Masterbatch brominated or halogen-free / is it regulatory compliant?
A masterbatch form of antimony trioxide synergist; dust-free handling reduces occupational exposure. Documentation available on request.
What is the typical dosage or concentration of ATO Masterbatch?
Let-down ratio is set to reach the target Sb2O3 loading in the compound, typically a few percent active.
How should ATO Masterbatch be stored and handled?
Store in a cool, dry, well-ventilated place away from heat, ignition sources and direct sunlight, in sealed original packaging and away from strong oxidisers. Refer to the SDS for full handling guidance.
What packaging and minimum order quantity does Haiwang offer for ATO Masterbatch?
ATO Masterbatch is supplied in bulk, typically as 25 kg bags or 500/1000 kg jumbo bags on pallets. Shandong Haiwang Chemical accommodates flexible MOQs for trial and full container-load orders – contact us for current options.
