Rigid Foam Polyols for Polyurethane Insulation Systems
Enviol manufactures high-performance rigid foam polyols for polyurethane insulation systems including PIR and PUF foam applications.
Our rigid polyurethane foam formulations are engineered for superior thermal insulation, dimensional stability, low thermal conductivity, and long-term structural performance.
These insulation systems are widely used in sandwich panels, cold storage insulation, refrigeration systems, insulated roofing panels, and industrial thermal insulation applications.
How Rigid Foam Systems Work
Rigid polyurethane foam is formed through a controlled reaction between polyol and polymeric MDI to create a closed-cell insulation structure.
In PIR systems, higher isocyanate index improves thermal stability, fire resistance, and dimensional performance at elevated temperatures.
In PUF systems, formulations are optimized for efficient insulation, processing stability, and cost-effective thermal insulation performance.
