FR211 halogen-free flame retardant is a phosphorus and nitrogen as the flame retardant element of environmentally friendly polyolefin flame retardant. Designed for a variety of flame-retardant polypropylene products can also be used for other polyolefin flame retardant products. FR211 acid source, gas source, carbon source, in order to charcoal, expansion mechanism plays a role in flame retardant. FR211 flame retardant PP, flame retardant to UL94-V0 (1.6mm).

　　As well as fire-retardant products, small density, low smoke, mold corrosion is small, excellent cost performance characteristics. Compared to other expansion of flame retardants, this product has a higher flame retardant effect and more excellent processing performance. When the combustion interval time is 10-15s, adding 30-35 parts can realize 0.8V0. And in the addition of 35 parts, 3.2mm spline for 30s Shi Yan, V0 still maintain the excellent results. The flame-retardant material will appear true color semi-permeable perfect appearance effect.
