Features Of TMG 250 Polyurethane Catalyst

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

  2. Low volatility and reduced odor profile, supporting improved workplace safety and compliance with VOC regulations.

  3. Excellent storage stability—remains effective for ≥12 months when stored under recommended conditions (dry, cool, sealed).

  4. Compatible with a wide range of polyols and isocyanates, including MDI- and TDI-based formulations.

  5. Enables precise control over cream, gel, and rise times—ideal for fine-tuning flexible slabstock and molded foam processing.

Typical Applications Of TMG 250 Polyurethane Catalyst

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

  2. Molded flexible foams used in automotive seating and interior components.

  3. High-resilience (HR) foam production requiring consistent cell structure and rebound performance.

  4. Water-blown and low-emission PU foam systems targeting sustainability certifications.

  5. Hybrid elastomer and semi-rigid foam applications demanding controlled reactivity and dimensional stability.
