摘要：
Syntactic polyurethanes are obtainable by reacting a polyisocyanate component a) with a polyol component, the polyol component b) comprising a polyetherpolyol based on a difunctional initiator molecule b1), a polyetherpolyol based on a trifunctional initiator molecule b2) and a chain extender b3), in the presence of hollow microspheres c). Furthermore, the syntactic polyurethanes are used for insulating offshore pipes and other parts and equipment used in the offshore sector, and the insulated offshore pipes as such are described.
