Acoustic damping material with improved adhesion at low temperatures

An acoustic damping material comprising:

• a) ≥0.75 wt.-%, based on the total weight of the acoustic damping material, of at least one polybutadiene PB comprising monomer units derived from 1,3-butadiene
• wherein the proportion of monomer units of the formula (I) in the entirety of the monomer units derived from 1,3-butadiene present in the polybutadiene is 25 to 75 mole percent, the proportion of units of the formula (II) in the entirety of the monomer units derived from 1,3-butadiene present in the polybutadiene is 0 to 10 mole percent and the proportion of monomer units of the formula (III) in the entirety of the monomer units derived from 1,3-butadiene present in the polybutadiene is 25 to 75 mole percent, wherein the entirety of the monomer units (I), (II) and (III) add up to 100 mole percent;
• b) ≥10 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;
• c) ≥3 wt.-%, based on the total weight of the acoustic damping material, of at least one butyl rubber BR;
• d) ≥3 wt.-%, based on the total weight of the acoustic damping material, of at least one natural or synthetic polyisoprene PI;
• e) 4-15 wt.-%, based on the total weight of the acoustic damping material, of at least one hydrocarbon resin HR;
• f) at least one solid particulate filler FM.
