Introduction
BX FR PVC ST series is a new type of flame retardant compounded with activated environmentally friendly flame retardant and environmentally friendly antimony trioxide. It is a white powder and has an excellent flame-retardant effect when used in PVC. It has the advantages of high-temperature resistance, fine particle size and good dispersibility. Widely used in PVC cables, wire materials, PVC coatings, PVC artificial leather, etc.
Product Features:
- Excellent flame retardant effect. Adding 3-6 parts to PVC can reach UL94-V0 (2mm);
- Reduce the generation of molten droplets during combustion;
- whiteness can reach the whiteness of antimony trioxide ≥95%;
- Meet environmental protection requirements.

Differences between PVC-ST3/PVC-ST4/PVC-ST6:
- Addition amount: 3 parts of PVC-ST3, 4 parts of PVC-ST4, and 6 parts of PVC-ST6 can reach UL94-V0 (2mm) in PVC;
- Price: PVC-ST6 is better than PVC-ST4 and PVC-ST3, but both are much lower than the price of antimony trioxide
- These products do contain antimony ingredients inside.
