Weihai cloud Qing Xu Cong ---PP dedicated environmental flame retardant properties: PP special environmentally friendly flame retardant is a nitrogen and phosphorus flame retardant is designed for polypropylene and halogen free, expansive flame retardant. It is by a synergistic effect of phosphorus containing nitrogen chemical polymerization, in polypropylene has good compatibility, of plastic impact on the mechanical properties is very small, and is excellent in processing stability during processing. The PP dedicated environmental protection flame retardant is different to halogen containing flame retardant, in the combustion process through dense expansion carbon layer achieve adiabatic isolation air flame retardant without irritating gaseous hydrogen halides and black smoke, is a kind of environmental friendly flame retardant. The
