Based on phosphorus-nitrogen synergistic flame retardant mechanism and independent-developed catalytic-synergistic flame retardant technology, KINGFA developed a new flame retardant polypropylene material with high heat resistance and low specific gravity. The new material has satisfied the strict requirements of portable sockets, such as glow wire flammability index(960℃), ball pressure temperature(125℃), low temperature impact test(-20℃) and needle flame burning test(30s). The specific gravity of the material is extremely low and there is no antimony element in the formula. It also has many advantages, like short molding cycle, high thermal stability during processing, excellent long-term aging resistance and weathering resistance, etc.
