Paste compsns. for clamping of vibration and noise contain >=1 polyglycol ether and for ester, ground graphite, >=1 wetting agent and opt. an organophilic Al silicate. In contrast to compsns. claimed in DT2647697, they do not cause swelling of elastomers, e.g. natural rubber. The pastes do not foam in service, have good heat conductivity and are self-sealing. They show a constant clamping action at high and low temps. and during prolonged loading, and absorb impact loads of high amplitude, making them suitable for sound-deadening, esp. for body shell vibrations. |
