PROCESS FOR PRODUCING ELASTIC POLYURETHANE MOULDINGS WITH COMPACT SURFACES AND CELLULAR CORES |
摘要 |
A process for the production of elastic polyurethane mouldings with compact surfaces and cellular cores by reacting a) modified organic polyisocyanates with b) at least one compound with at least two reactive hydrogen atoms and possibly c) chain-lengthening agents in the presence of d) blowing agents, e) catalysts and possibly f) conventional auxiliaries and/or additives, in a closed mould under compression, in which at least one reaction product of pure MDI and at least one polyether alcohol (polyoxyalkylene polyol) with an NCO content of < 15 wt.% is used as the modified organic polyisocyanate.
