Document Type and Number:
Japanese Patent JP6193372
Kind Code:
B2
Abstract:
The present invention relates to a continuous method for the production of an insulated tube comprising at least one medium tube, a shell tube, a layer of at least one polyurethane between the at least one medium tube and shell tube and a film sleeving between the at least one polyurethane and the shell tube, comprising at least the steps (A) providing at least one medium tube and one film sleeving continuously formed from a film in a gripper-belt, wherein the at least one medium tube is arranged inside the film sleeving in such a manner that between the at least one medium tube and film sleeving a gap is formed, (B) charging a polyurethane system comprising at least one isocyanate component (a) and at least one polyol (b) into the gap, (C) foaming and curing the polyurethane system, and (D) applying a layer of at least one material to the film sleeving in order to form the shell tube, wherein the polyurethane system has thixotropic properties.
