Abstract: HOE 85/H 025 JK FLAME-RETARDANT AGENTS STABLE TO HYDROLYSIS, BASED ON AMMONIUM POLYPHOSPHATE A flame-retardant agent based on free flowing, pulverulent ammonium polyphosphate of the general formula H(n-m)+2(NH4)mPnO3m+1 in which n stands for an integer with an average value of: about 20 to 800 and the ratio of m/n is about 1, consists substantially of a) about 75 to 99.5 mass % ammonium polyphosphate and b) about 0.5 to 25 mass % of a reaction product of a polyisocyanate and a trimerization catalyst, the resulting polyisocyanurate encapsulating the individual ammonium polyphosphate particles.

Abstract: DIFFICULTLY FLAMMABLE EXTRUDED ARTICLES, ESPECIALLY EXTRUDED BOARDS, AND DIFFICULTLY FLAMMABLE VENEERED OR COATED EXTRUDED BOARDS, A PROCESS FOR MAKING THEM AND THEIR USES The disclosure relates to difficultly flammable wooden articles, especially chip boards comprising solid and pipe boards, prepared by extrusion from wooden chips and/or woody fibrous materials. The articles contain as a flame-retarding addend a product of a) 50 to 99.5 weight % of a flame-retarding agent physi cally and chemically stable under extrusion conditions, preferably 75 to 99.5 weight % of a pulverulent, freeflowing ammonium polyphosphate of the general formula H(n-m)+2(NH4)mPnO3n+1 in which n stands for a whole number with an average value of about 20 to 800 and the ratio of m/n is about 1, and b) about 0.5 to 50 weight % of a cured water-insoluble artificial resin encapsulating the individual particles of the flame-retarding agent or ammonium polyphosphate. The disclosure also relates to difficultly flammable boards veneered with wood or a laminate.

Abstract: Self-extinguishing polymeric composition based on a polyolefin, especially polypropylene, of improved thermal stability containing an intumescent fire-retardant system comprised of a phosphorus constituent and a carbonaceous nitrogen constituent. The composition contains more particularly, as the phosphorus constituent, a product consisting substantially of (a) 75-99.5 wgt % pulverulent free flowing ammonium polyphosphate of the following general formula H(n-m)+2(NH4)mPnO3n+1 in which n stands for an integer having an average value of from about 20 to 800 and the ratio of m/n is about 1, and (b) about 0.5-25 wgt % of a water-insoluble, optionally cured artificial resin encapsulating the individual ammonium polyphosphate particles.

Abstract: The disclosure relates to a process for making a particulate agent stable to hydrolysis based on free-flowing, pulverulent ammonium polyphosphate by treating the ammonium polyphosphate with a thermosetting, artificial resin being water-insoluble when cured. More specifically, the disclosure provides for the ammonium polyphosphate, an aliphatic alcohol as a diluent, and a melamine/formaldehyde-resin or phenol/formaldehyde-resin to be placed in an autoclave and intimately mixed at room temperature; for the mixture to be heated to a temperature of about 80 DEG to about 180 DEG C. and allowed to remain over a period of 15 to 240 minutes at that temperature and under the pressure corresponding to the vapor pressure of the diluent; for the diluent to be separated and for the product so obtained to be dried.
