Features Of INOVOL C 280 Polyether Polyols

  1. Highly consistent hydroxyl functionality (f ≈ 2.8) ensures predictable crosslink density in polyurethane networks.

  2. Low monool content (< 0.5%) enhances polymer backbone integrity and improves mechanical performance of final foams and elastomers.

  3. Controlled molecular weight distribution (PDI < 1.08) delivers excellent batch-to-batch reproducibility for industrial-scale production.

  4. Optimized ethylene oxide capping provides balanced reactivity, improved compatibility with aromatic isocyanates, and enhanced hydrolytic stability.

  5. Low residual catalyst levels (< 5 ppm K) minimize discoloration and extend pot life in sensitive formulations.

Typical Applications Of INOVOL C 280 Polyether Polyols

  1. Flexible molded polyurethane foams for automotive seating and interior components.

  2. High-resilience (HR) slabstock foams used in premium mattresses and upholstered furniture.

  3. Microcellular elastomers for gaskets, seals, and vibration-damping parts.

  4. Reaction injection molding (RIM) systems requiring fast demold times and dimensional stability.

  5. Coating and adhesive formulations where flexibility, adhesion, and low-temperature performance are critical.
