Features Of TMG 220 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst for balanced reactivity in polyol–isocyanate reactions.

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

  3. Excellent compatibility with common polyether and polyester polyols, as well as aromatic and aliphatic isocyanates.

  4. Enables precise control over cream-to-gel timing in flexible slabstock and molded foam systems.

  5. Stable under standard storage conditions with no significant decomposition over 12 months at room temperature.

Typical Applications Of TMG 220 Polyurethane Catalyst

  1. Flexible polyurethane foam for mattresses and furniture cushioning.

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

  3. Integral skin (self-skinning) foams for steering wheels, dashboards, and decorative trim.

  4. Slabstock foam production requiring consistent cell structure and dimensional stability.

  5. Water-blown low-density foams where reduced emissions and processing safety are critical.
