XS-PPSH Halogen Free Flame Retardant For Polyolefin

2016-10-22 15:47
XS-PPSH is a kind of intumescent halogen free and mixed P&N based flame retardants for polyolefin, it can meet the requirements of ROHS. Once it is used in polyolefin materials,the materials will form a charring layer with so many holes when fire occurs,such charring layer can insulate oxygen and heating, then delay the process of burm and extinguish gradually and avoid dropping effectively. It has the property of smoking suppression, doesn’t release toxic and abrasive gases, no immigration and insoluble in water. It can pass the water-resistance test for 168 hours, and it has excellent thermal stability and processing perfofmance.
