Features Of WANOL POP 3630 Polyether polyols

  1. Highly reactive tertiary amine-functionalized polyether polyol for enhanced urethane/urea kinetics.

  2. Excellent compatibility with aromatic and aliphatic isocyanates in both flexible and semi-rigid foam systems.

  3. Delivers superior load-bearing capacity and dimensional stability in molded and slabstock foams.

  4. Low volatility and favorable handling characteristics—non-hygroscopic and easy to pump and meter.

  5. Enables reduced catalyst demand while maintaining consistent cell structure and processing window.

Typical Applications Of WANOL POP 3630 Polyether polyols

  1. Automotive seating foams (driver/passenger seats, headrests, armrests).

  2. Industrial packaging foams requiring high resilience and crush resistance.

  3. Commercial furniture cushioning for office chairs and sofas.

  4. Semi-rigid automotive interior parts (dashboards, door panels, pillar trims).

  5. High-performance bedding and mattress comfort layers.
