Antimony Base Flame-retardant Synergist ST-FS-A390T
2023/4/20
Product Profile
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.
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.
