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.
