发明名称 Cellular, molded polyurethane parts, process for their preparation by thermoforming of polyester-urethane foam and their use
摘要 A cellular polyurethane having a density of from 15 Kg/m3 to 400 Kg/m3 obtained by means of thermoforming, in a forming tool, at a compression factor of from 1 to 10 and temperatures of from 140 DEG C. to 200 DEG C., polyester-urethane foams having a density of from 15 Kg/m3 to 40 Kg/m3 which are based on aromatic polyisocyanates and polyester polyols. The resulting polyurethane shaped objects are suitable for use as self-supporting trim panels, headliners, engine compartment covers, or instrument panels in the automotive, aircraft or railway industries.
