Features Of TMG 225 Polyurethane Catalyst

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

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

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

  4. Compatible with a broad range of polyols, isocyanates, and co-catalysts including DABCO® and TEDA derivatives.

  5. Enables fine-tuned control over cream time, rise profile, and gelation—ideal for high-resilience and slabstock foam formulations.

Typical Applications Of TMG 225 Polyurethane Catalyst

  1. Flexible polyurethane slabstock foams for bedding and furniture.

  2. High-resilience (HR) molded foams used in automotive seating and premium upholstery.

  3. Integral skin foams for steering wheels, armrests, and dashboard components.

  4. Water-blown and low-VOC foam systems requiring reduced emissions and odor.

  5. Multi-component spray polyurethane foam (SPF) sealants and insulation systems.
