Features Of TMG 623 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for balanced gelling and blowing reactions in polyurethane systems.

  2. Low volatility and reduced odor profile, supporting improved workplace safety and regulatory compliance (e.g., REACH, VOC guidelines).

  3. Excellent solubility and compatibility with common polyols, isocyanates, and formulation additives.

  4. Enables precise control over cream time, rise time, and demold time in flexible and semi-rigid foam production.

  5. Stable under standard storage conditions with extended shelf life when kept sealed and dry.

Typical Applications Of TMG 623 Polyurethane Catalyst

  1. Flexible slabstock polyurethane foams for bedding and furniture.

  2. Semi-rigid automotive seating and interior trim foams.

  3. Integral skin foams used in steering wheels, armrests, and dash components.

  4. Reaction injection molding (RIM) and structural foam applications.

  5. Water-blown and low-VOC foam formulations requiring reduced emissions.
