FOAM INSULATION BOARD FACED WITH A TOUGH POLYMERIC FILM OR COMPOSITE THEREOF

摘要

A method for continuously manufacturing an insulation board by facing a foam--forming composition with one or two facing sheets to form a singly or doubly faced composite, at least one sheet comprising either a tough polymeric layer or a laminate of a tough polymeric layer with at least one other facing material, the tough polymeric layer of at least one sheet facing to the outside of the composite, and foaming an d curing the faced foam-forming mixture to produce an insulation board having an exceptional hardness and puncture resistance.
