A process for preparing oil and petroleum-resistant cellular to solid (polyurea)polyurethanes (PURS) with improved physical properties in which a polyether polyol component having a number average molecular weight of from 1000 to 8000 and a polyester polyol component having a number average molecular weight of from 1000 to 6000 are reacted with a polyisocyanate and the (polyurea) polyurethanes produced by that process. The (polyurea)polyurethanes are particularly useful for personal safety equipment and in the construction of automobiles.

Polyurea polyrethanes having improved physical properties

The invention provides polyurethane elastomers (PU elastomers), a process for their production using special catalyst mixtures and their use in particular for the manufacture of shoe soles.

Polyurethane elastomers, process for their production and use thereof

Safety clothing is produced by molding polyether-based plastic-forming compositions. Particularly preferred articles of safety clothing produced by this process are safety shoe soles.

Use of polyether-polyurethane for safety clothing

A process for the CFC-free production of cellular polyurethane molded parts/articles with solid surfaces by reacting a reaction mixture of per se known starting materials in sealed molds, to yield polyurethane foams. Carbamates obtainable from aliphatic aminoalcohols and carbon dioxide are used as blowing agents, optionally in conjunction with other blowing agents. The process is suitable for producing foam coverings on steering wheels, spoilers and protective upholstery in car interiors, and for producing soles of shoes or shoe components.

Process for the CFC-free production of cellular polyurethane molded parts

The present invention is directed to an integral skin foam prepared by reacting a specific isocyanate, a specific isocyanate reactive component and water as the only blowing agent.

Water-blown integral skin polyurethane foams

The instant invention is directed to a process for the production of a cellular polyurethane elastomer having a density of 0.45 to 0.8 g/cm.sup.3, comprising:
