  • Cellular elastomer with little tendency toward creep at high temperatures
    Patent number: 8927613
    Abstract: The present invention relates to cellular polyisocyanate polyaddition products whose density to DIN EN ISO 845 is from 200 to 800 kg/m3, and also to prepolymer composed of at least one diisocyanate (a) and of at least one polyether alcohol (b), where the at least one polyether alcohol (b) comprises the following components: (b1) aliphatic polyether alcohols whose number-average molar mass is from 300 to 1000 g/mol, (b2) aliphatic polyether alcohols whose number-average molar mass is from 2000 to 10 000 g/mol, and (b3) aliphatic polyether alcohols whose number-average molar mass is from 10 000 to 100 000 g/mol, to a process for its production, to a cellular polyisocyanate polyaddition product thus produced, and to its use as damping elements in vehicle construction.
    Type: Grant
    Filed: July 14, 2009
    Date of Patent: January 6, 2015
    Assignee: BASF SE
    Inventors: Frank Prissok, Joern Duwenhorst, Michael Harms, Sven Lasai
  • Anisotropic cellular elastomers
    Patent number: 8282851
    Abstract: The invention relates to a cellular elastomer which is anisotropic, with anisotropy being defined by the compressive modulus in one of three orthogonal directions being greater than that in the other two directions by a factor of at least 1.5. The invention also relates to a cellular elastomer containing magnetizable particles which have a chain-like alignment along one spatial direction. The invention also relates to a process for producing a cellular elastomer containing magnetiable particles and the use of such elastomers in articles of manufacture.
