Polyiso (PIR) foam panels are en evolution of traditional polyurethane panels, based on a different ratio among the main raw material, and on significant plant innovations. PIR foam is mainly distinguished by the highest number of chemical links and the wider curing with high stabilization energy. These characteristics form macromolecules made of stronger chemical links, compared to the polyurethane ones.
The main performance advantages with respect to PIR foams are:
- Fire reaction;
- Dimensional stability;
- Compressive strength;
- Dampening effect;
- Resistance to solvents;
- Resistance to UV rays and oxidation.
All the STIFERITE insulation products, including ISOCANALE brand, are made of polyiso foam.
