AP766 flame retardant ProFlame® PNPO-766 (AP766) PNPO-766 is a kind of Halogen-Free flame retardant , which develops its effectiveness through phosphorus/nitrogen synergism.When the polyolefine on exposure to flame, the carbon foam layer formed protects the polymer through its heat insulating effect to reduce further oxygen access and prevent dripping of the polymer. At the sam…
