High-performance waterproof PIR foam insulation boards with excellent fire resistance and structural strength for industrial applications.
Polyisocyanurate (PIR) is a high-performance foaming material created through the polymerization of isocyanate and polyether. Offering superior physical and fire resistance properties compared to polyurethane, PIR features minimal thermal conductivity and exceptional dimensional stability as an organic rigid thermal insulation material.
