Rigid Foam Polyols
Rigid polyurethane foam systems are closed-cell polymer networks formed by the reaction of polyols with isocyanates.
These systems are engineered for high thermal insulation, structural stability, and long-term durability.
They are widely used in insulation boards, refrigeration panels, sandwich panels, and cold storage applications.
How Rigid Foam Systems Work
Rigid polyurethane foam is formed through a controlled reaction between polyol and polymeric MDI.
In PIR systems, higher isocyanate index improves thermal stability and fire resistance.
In PUF systems, formulation is optimized for cost-effective insulation and flexibility.
