General Information

Use as attenuation layer with large deflection, permanently elastic intermediate layer for sandwich constructions, spring elements, buffer, damping elements in the shop, in the laboratory, pilot plant, and factory.

High tensile strength and notch impact strength

Extremely high volume compressibility

High tearing strength

Good behavior in cold

Good resistance to aging and weather

Low compression set

Good oil resistance, limited resistance to gasoline, not recommended to acids and bases

This quality is a microcellular polyurethane elastomer. The cell structure is formed in the foaming process without blowing agent, free of pollutants.

All conventional elastomers are not volume compressible and have to be built in in such a way that an unlimited deformation to the side is possible at deflection. If this is not guaranteed, only very limited spring deflections can be realized.

The material cannot be defined using the shore hardness A. In this case, the differentiation is made by density.
