1. Product Introduction
PIR foam VFOAM-01 is a rigid insulation material, produced through the reaction of isocyanate and poly. It has better fire resistance performance than polyurethane foam. In addition, PIR foam has low thermal conductivity, wide service temperature range, and excellent dimension stability properties. It can be cut into a pipe cover and flat or board easily. PIR foam insulation meets the standards of ASTM C591 and CINI 2.7.01.
