Highly consistent hydroxyl functionality (f ≈ 3.0) for predictable crosslink density in rigid PU foams.
Optimized molecular weight distribution delivering excellent flow properties and cream-to-gel time control.
Low monool content (<0.5%) ensuring superior polymer network formation and dimensional stability.
Excellent compatibility with common isocyanates (e.g., PMDI, TDI) and flame retardants used in construction insulation.
Stable viscosity profile across storage temperatures (15–35 °C), minimizing process variability in continuous foam lines.
Rigid polyurethane insulation boards for building envelope systems.
Spray-applied foam for roofing and cavity wall insulation.
Structural insulated panels (SIPs) core material.
Refrigeration cabinet and cold storage panel fillers.
Industrial pipe insulation with enhanced thermal resistance.
