I. Product Introduction: 

1. Excellent flame retardant effect. Achieves the effect of extinguishing as soon as the fire source is removed: V2 (0.8-3.2mm). 

2. High flame retardant efficiency. And there is no need to add synergists such as antimony trioxide. 

3. Good compatibility of the flame retardant. The final product has a high gloss, no precipitation, and no blooming. 

4. Outstanding mechanical properties. It does not change the original impact resistance, tensile strength, bending resistance and other properties of the product. 

5. Fillers such as calcium carbonate, barium sulfate, and talcum powder can be added. 

6. Complies with the environmental protection requirements of ROHS and REACH. It can be exported. 

III. Scope of Application
