Features Of TMG 129 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for balanced reactivity in polyurethane foam systems.

  2. Low volatility and minimal odor, supporting improved workplace safety and reduced VOC emissions.

  3. Excellent compatibility with common polyols, isocyanates, and auxiliary additives in flexible and semi-rigid formulations.

  4. Enables precise control over cream time and rise profile without compromising final foam density or cell structure.

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

Typical Applications Of TMG 129 Polyurethane Catalyst

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

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

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

  4. Water-blown low-emission foam systems compliant with indoor air quality standards.

  5. Two-component spray-applied polyurethane insulation foams.
