Polyisocyanurate (PIR) is a foaming material created through the polymerization of isocyanate and polyether. With superior physical and fire resistance properties compared to polyurethane, PIR offers excellent thermal insulation with minimal conductivity and outstanding dimensional stability, making it an ideal organic rigid insulation material.
- B1 fire resistance rating
- Operating temperature range: -196℃ to +120℃
- Exceptional dimensional stability
- Customizable as panels or pipes to meet specific requirements
