Features Of INOVOL C 303 Polyether polyols

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

  2. Consistent hydroxyl value (OHV) and narrow molecular weight distribution ensure reproducible foam performance.

  3. Excellent compatibility with common isocyanates and auxiliary additives in flexible polyurethane systems.

  4. Low monool content and controlled unsaturation support high reactivity and crosslink density.

  5. Stable storage characteristics with minimal color development over time under recommended conditions.

Typical Applications Of INOVOL C 303 Polyether polyols

  1. Flexible slabstock polyurethane foams for bedding and furniture.

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

  3. Integral skin foams for automotive armrests and dash components.

  4. Carpet underlay and acoustic damping composites.

  5. Specialty elastomers requiring balanced resilience and compression set resistance.
