Features Of TMG 232 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for polyol-isocyanate reaction kinetics.

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

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

  4. Enables balanced reactivity—promotes gelation without excessive blowing—ideal for structural foam and elastomer systems.

  5. Stable under ambient storage conditions; non-corrosive to standard processing equipment.

Typical Applications Of TMG 232 Polyurethane Catalyst

  1. Flexible molded polyurethane foams for automotive seating and interior components.

  2. Slabstock flexible foams used in bedding and furniture manufacturing.

  3. Reaction injection molding (RIM) and reinforced RIM (RRIM) elastomers.

  4. Microcellular polyurethane sealants and gasketing compounds.

  5. High-resilience (HR) foam formulations requiring precise cure profile control.
