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 foamforming 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 and curing the faced foam-forming mixture to produce an insulation board having an exceptional hardness and puncture resistance.
