Product description: FR-NP300 is a non-halogenated flame retardant based on phosphorus/nitrogen synergism. When incorporated into thermoplastics, in shows good processing stability and non-hydroscopic. FR-NP300 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The thermoplastic material foams on exposure to flame, the carbon foam layer so formed protects the polymer through its heat-insulating effect, reduces further oxygen access and prevents dripping of the thermoplastic. FR-NP300 does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), or polybrominated diphenyl ethers (PBDEs). It is compliant with the requirements of RoHS & WEEE Directive and halogen-free specification IEC 61249-2-21
