Abstract
Polyurethane elastomer production is claimed in which the polyisocyanate component used together with high mol. wt. polyhydroxy components and optionally also low mol. wt. chain extenders and/or crosslinkers, catalysts, foaming agents etc comprises: (A) 1,4-phenylene diisocyanate; and (B) toluene diisocyanate, diphenylmethane diisocyanate, 3,3-dimethyl-diphenyl-diisocyanate, 1,2-diphenylethane-diisocyanate and/or a 4-12C aliphatic- and/or 6-18C cycloaliphatic-diisocyanate. Also claimed are prepolymers of NCO group content 3.3-10 wt.% obtained by reaction of the polyhydroxy component and optionally the chain extender and/or crosslinker with (B) to give a urethane polyaddition product of NCO content of 0.05-8 wt.% which is then reacted with (A). The aliphatic and cycloaliphatic diisocyanates in this instance are 1,6-hexamethylene diisocyanate and 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl-cyclohexane.
