FOAMABLE TWO-COMPONENT POLYURETHANE MATERIAL

摘要

The invention concerns a foamable two-component polyurethane material which can be used for instance to produce freely foamed seals on a surface or in a groove. The invention also concerns certain individual components of this material and articles made from the material. A significant aspect of the invention is the fact that a two-component material of this kind is designed in such a way that one component (A) is a polymeric polyol with essentially only two hydroxy groups per molecule and the other component (B) is an essentially bifunctional isocyanate, the material also optionally including the usual additives.
