Fremgangsmåde til fremstilling af varmeisolerende strukturelle elementer og derved opnåede produkter

摘要

A process for preparing heat-insulating structural elements is described, which comprises the following steps: (a) applying to the convex portion of a first half-shell a layer of beads of semi-foamed or foamed thermoplastic polymer, so as to form a layer of substantially uniform thickness; (b) sintering the beads; and (d) applying to the composite thus obtained a second half-shell which matches the shape of the sintered layer.
