Highly consistent hydroxyl functionality (f ≈ 3.0) for predictable crosslink density in rigid PU foams.
Optimized molecular weight distribution to enhance foam dimensional stability and thermal insulation performance.
Low monool content (<0.5%) ensuring improved polymer network integrity and reduced shrinkage.
Excellent compatibility with common isocyanates (e.g., PMDI) and flame retardants used in construction-grade formulations.
Stable viscosity profile across storage temperatures (20–40 °C), supporting reliable metering and processing in continuous line operations.
Rigid polyurethane insulation boards for building envelope systems (walls, roofs, cold storage).
Spray-applied rigid foam for industrial pipe insulation and tank jacketing.
Structural sandwich panels in prefabricated construction and refrigerated transport.
High-efficiency appliance insulation (refrigerators, freezers, water heaters).
Fire-retardant PU formulations meeting EN 13501-1 Class B-s1,d0 or ASTM E84 Class A requirements.
