The ignitability (by the oxygen index method) and smoke generation (in NBS chamber) by glass-polyester laminates based on maleic-fumaric-phthalic-epichlorohydrin resins with incorporated Cl and Br atoms (Polimal 160 and Polimal 161) and containing added melamine diphosphate (DFM), AI(OH)3 or Mg(OH)2 have been determined. It has been found that DFM reduces ignitability and prolongs the period to initiation of smoke generation in a much higher degree than the remaining two additives. DFM also increases the total amount of generated smoke and the maximum rate of its generation. The investigated GRP laminates meet the fire-protection requirements in public transportation means both in Poland and in the U.S.A.
