Features Of DY-1 Strong Foaming Catalyst

  1. Highly efficient nitrogen-based foaming activation for rapid and uniform cell nucleation in polyurethane systems.

  2. Excellent compatibility with aromatic and aliphatic isocyanates, ensuring stable foam structure across diverse formulations.

  3. Low odor and low volatility, supporting safer handling and reduced VOC emissions during processing.

  4. Thermally stable up to 180°C, enabling consistent performance in high-temperature molding and continuous slabstock production.

  5. Precise reactivity tuning—delivers adjustable cream time and rise profile without compromising final foam density or mechanical integrity.

Typical Applications Of DY-1 Strong Foaming Catalyst

  1. Flexible polyurethane slabstock foam for mattresses and upholstered furniture.

  2. High-resilience (HR) molded foam components in automotive seating and interior trim.

  3. Integral skin foams used in steering wheels, armrests, and dashboard pads.

  4. Fire-retardant PU foams requiring balanced reactivity and char-forming additive compatibility.

  5. Water-blown eco-friendly foam systems targeting low-GWP manufacturing standards.
