Starbetter Chemical Materials Antimony Based Flame Retardant Synergist ST-FS-A390T

Starbetter Chemical Materials Antimony Based Flame Retardant Synergist ST-FS-A390T can replace ATO with good properties. This product can not only save the cost, but also has less content of Pb, As and Hg than ATO. Most formulas of soft PVC products are using antimony trioxide (ATO) as flame-retardant synergist. Meanwhile, the price of ATO is increasing rapidly and unpredictable and the antimony resource is getting less. It leads to the higher cost for most flame-retardant compounding manufacturers.

Functions: Flame Retardant

Chemical Family: Antimony & Antimony Compounds, Copper-based Compounds, Iron & Iron Compounds, Iron Oxides, Lead Compounds (Pb)

Compatible Polymers & Resins: Polyvinyl Chloride (PVC)
