Features Of WANOL F 3128 Polyether polyols

  1. Low-viscosity, trifunctional propylene oxide–initiated polyether polyol for improved processability.

  2. Consistent hydroxyl number (OH#) and narrow molecular weight distribution ensure batch-to-batch reliability.

  3. Excellent compatibility with common isocyanates (e.g., MDI, TDI) and formulation additives.

  4. Low volatile organic compound (VOC) content, supporting sustainable manufacturing and regulatory compliance.

  5. Hydrolytically stable backbone structure enhances shelf life and long-term formulation integrity.

Typical Applications Of WANOL F 3128 Polyether polyols

  1. Flexible slabstock polyurethane foams for bedding and upholstered furniture.

  2. High-resilience (HR) molded foams used in automotive seating and premium cushioning.

  3. Integral skin foams for steering wheels, armrests, and dashboard components.

  4. Water-blown or low-blowing-agent foam systems requiring balanced reactivity and cell structure control.

  5. Adhesives and sealants where moderate crosslink density and flexibility are required.
