XAP-01 is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. XAP-01differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access. Intumescent coatings.
XAP-01 may be used in a range of thermoset resins, especially unsaturated polyester resin, acrylic resins, epoxy or phenolics. It is suitable both for coatings and reinforced materials. In addition to primary effects of fire such as spread of flames and residual length, secondary effects such as smoke density and formation of toxic smoke is of interest. Using XAP-01 a low smoke density is achieved. By the addition of XAP-01 in polyester gel coats important. In composites XAP-01 can be used alone or in combination with synergists like aluminium hydroxide.
