Features Of TMG 218 Catalyst

  1. Highly selective for low-temperature urethane formation without side reactions.

  2. Thermally stable up to 180°C, enabling robust performance in demanding processing conditions.

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

  4. Compatible with common polyols, isocyanates, and blowing agents used in flexible and rigid foam systems.

  5. Non-corrosive to standard stainless steel and aluminum process equipment.

Typical Applications Of TMG 218 Catalyst

  1. Flexible polyurethane slabstock foam for mattresses and furniture cushioning.

  2. Rigid polyurethane and polyisocyanurate insulation foams for construction and refrigeration.

  3. Integral skin (self-skinning) foams for automotive seating and medical device components.

  4. Coating and adhesive formulations requiring controlled reactivity and extended pot life.

  5. Reaction injection molding (RIM) systems requiring precise gel–rise balance.
