Description of PIR Polyisocyanurate Foam

PIR polyisocyanurate foam is a foaming material made by the reaction of isocyanate with polyether through the action of a catalyst. It has the advantages of low thermal conductivity, wide operating temperature range, excellent dimensional stability, and free cutting of pipes and plates according to customer requirements. It is widely used in exterior wall and roof insulation, pipe insulation, industrial equipment and machinery.

Excellent thermal insulation.
Fire resistance.
Chemical stability.
High compressive strength.
