syntactic polyurethanes and their use in the off shore insulation

摘要

The invention relates to syntactic polyurethanes, obtainable by reacting a polyisocyanate component (a) with a polyol component (b), in the presence of hollow microspheres (c) and encapsulated latent heat stores (d). The invention furthermore relates to the use of the syntactic polyurethanes for insulating offshore pipes, and insulated offshore pipes as such, and other parts and apparatuses used in the offshore sector.
