XS-FR-3300

XS-FR-3300 series is a phosphorus and nitrogen compound halogen-free flame retardant, which is a white powder. When the polyamide resin added with this product is thermally cracked or burned, a porous carbon layer is formed on the surface of the resin by foaming and expanding, which plays the role of heat insulation, oxygen insulation and prevention of molten droplets. This product also has a certain effect of inhibiting smoke generation, and does not generate toxic or corrosive gases.


In addition, this product does not absorb water and does not precipitate, has excellent thermal stability and processing performance, and is a popular and efficient environment-friendly flame retardant.
