The invention relates to a polyol mixture which comprises as components These polyol mixtures can be employed to produce polyurethane-based embedding compositions. The invention additionally relates to embedding compositions based on the polyol mixtures (A) described at the outset and at least one modified isocyanate (B) and to the use of the embedding compositions as potting material. The invention further relates to a process for producing the embedding compositions as described at the outset. The invention additionally relates to dialysis filters which comprise the embedding compositions described at the outset. Finally, the invention relates to the combination of components (A) and (B) which are present separately but are to be used together.

Casting compounds based on polyurethane

The invention relates to a process for the preparation of polyurethanes by reacting polyisocyanates a) with compounds having at least two hydrogen atoms reactive with isocyanate groups b), wherein a polyisocyanate a) used is at least one polyisocyanate ai) having an average functionality of greater than 2, a content of diisocyanates of not more than 2% by weight and a content of uretonimines of not more than 4% by weight, based in each case on the weight of the polyisocyanate ai).

Process for preparing polyurethanes

The present invention relates to a process for producing a polyurethane lamination resin, by mixing a) an isocyanate prepolymer based on diphenylmethane diisocyanate having a difunctionally started polyether, b) polyphenylene polymethylene polyisocyanate, c) trifunctionally started polyetherpolyol with an average molar mass of from 350 to 600 g/mol, d) a thermoactivatable capped catalyst, e) if appropriate, chain extender and/or crosslinking agent, f) if appropriate, water-absorbent substances, and g) if appropriate, other additives to give the polyurethane lamination resin. The present invention further relates to a polyurethane lamination resin, obtainable via a process of this type, and to the use of this type of polyurethane lamination resin for producing laminates, and also to skis or snowboards, comprising this type of laminate.
