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

摘要

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.
