Features Of YOKE TEDA-33 Polyurethane Catalyst

  1. Highly efficient tertiary amine catalyst specifically optimized for flexible slabstock polyurethane foam production.

  2. Excellent balance of cream, gel, and tack-free times for consistent foam cell structure and dimensional stability.

  3. Low volatility and reduced odor profile compared to conventional DABCO®-type catalysts, supporting safer handling and improved workplace air quality.

  4. Good compatibility with common polyol systems and low-reactivity isocyanates (e.g., MDI prepolymers), enabling formulation flexibility.

  5. Stable performance across a broad temperature range (15–35 °C), minimizing batch-to-batch variability in industrial manufacturing.

Typical Applications Of YOKE TEDA-33 Polyurethane Catalyst

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

  2. Automotive interior foams including seat cushions, headrests, and armrests.

  3. Carpet underlay and acoustic insulation foams requiring controlled rise kinetics.

  4. Industrial packaging foams where consistent density distribution and surface integrity are critical.

  5. Composite laminates and spray-applied foam systems utilizing slow-reacting polyol blends.
