Our High Closed-Cell Polyisocyanurate (PIR) foam is a rigid insulation material formed by the precise polymerization of isocyanate and polyether. The exceptionally high closed-cell content of ≥95% creates a structure of isolated cells, which translates directly into extremely low thermal conductivity, outstanding dimensional stability, and minimal water vapor permeability. With overall performance that surpasses standard polyurethane (PU), it is the ideal choice for demanding industrial applications.
