Zusammenfassung:	The use of flowable reaction mixtures essentially comprising A) a polyol component comprising A1) at least one linear or slightly branched polyester-polyol having an OH number of 40 to 500, A2) from 0 to 50 % by weight, based on A1), of at least one polyetherpolyol having an OH number of from 40 to 500 and A3) from 0 to 5 % by weight, based on A1), of at least one low-molecular-weight, polyhydric alcohol having an OH number of above 500, B) a polyiscocyanate component comprising a polyisocyanate mixture from the diphenylmethane series which is liquid at room temperature and has an NCO content of from 10 to 33 % by weight in such an amount that from 3 to 20 NCO groups of component B) are present per hydroxyl group from component A), C) catalysts for the trimerisation reaction of isocyanate groups, and optionally D) further auxiliaries and additives, as encapsulating or embedding compositions.
