An acoustic damping material with improved fire resistance

An acoustic damping material comprising:

• a) 6-25 wt.-%, based on the total weight of the acoustic damping material, of at least one at 25° C. liquid rubber LR selected from the group consisting of at 25° C. liquid polybutenes and at 25° C. liquid polyisobutylenes;
• b) 3-15 wt.-%, based on the total weight of the acoustic damping material, of at least one component CP selected from the group consisting of butyl rubber BR, natural or synthetic polyisoprene PI and polyisobutylenes PIB with a weight average molecular weight of ≥250,000 g/mol;
• c) 37.5-52.5 wt.-%, based on the total weight of the acoustic damping material, of at least one component D selected from the list consisting of ammonium polyphosphate APP and melamine compound M,
• d) 0.5-2.5 wt.-%, based on the total weight of the acoustic damping material, of at least one component E selected from phosphates, pyrophosphates, polyphosphates, organic and inorganic phosphonates, organic and inorganic phosphinates of the elements of the main groups II, III or IV or the transition group elements Fe, Zn, Ti, Mn, Zr and Mo;
• e) at least one solid particulate filler FM, preferably at least one solid particulate mineral filler FM.
