Features Of TMG 233 Polyurethane Catalyst

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

  2. Low volatility and minimal odor, supporting safer handling and improved workplace air quality.

  3. Excellent compatibility with common polyols, isocyanates, and auxiliary additives across flexible and rigid formulations.

  4. Enables precise control over cream, rise, and gel times—ideal for molded and slabstock foam production.

  5. Non-corrosive to processing equipment and stable under standard storage conditions (25°C, dry environment).

Typical Applications Of TMG 233 Polyurethane Catalyst

  1. Flexible slabstock polyurethane foam for bedding and furniture.

  2. Rigid polyurethane and polyisocyanurate (PIR) insulation foams for construction and refrigeration.

  3. Automotive seating and interior trim foams requiring consistent cell structure and low emissions.

  4. Integral skin and microcellular foams used in automotive dashboards and armrests.

  5. Water-blown and low-VOC foam systems compliant with global environmental regulations.
