Features Of WANOL R 8345 Polyether polyols

  1. Highly consistent hydroxyl functionality (f ≈ 3.0) for predictable crosslink density in rigid PU foams.

  2. Optimized molecular weight distribution delivering excellent flow properties and cream-to-gel time control.

  3. Low monool content (<0.5%) ensuring superior polymer network formation and dimensional stability.

  4. Excellent compatibility with common isocyanates (e.g., PMDI, TDI) and flame retardants used in construction insulation.

  5. Stable viscosity profile across storage temperatures (15–35 °C), minimizing process variability in continuous foam lines.

Typical Applications Of WANOL R 8345 Polyether polyols

  1. Rigid polyurethane insulation boards for building envelope systems.

  2. Spray-applied foam for roofing and cavity wall insulation.

  3. Structural insulated panels (SIPs) core material.

  4. Refrigeration cabinet and cold storage panel fillers.

  5. Industrial pipe insulation with enhanced thermal resistance.
