Features Of TMG 315 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for polyurethane foam gelation control.

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

  3. Excellent compatibility with common polyols, isocyanates, and auxiliary catalysts in PU systems.

  4. Enables balanced reactivity—promotes early gelation without excessive blow reaction interference.

  5. Stable liquid formulation with extended shelf life under recommended storage conditions.

Typical Applications Of TMG 315 Polyurethane Catalyst

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

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

  3. Semi-rigid automotive interior foams including headrests, armrests, and dash pads.

  4. Water-blown or low-VOC PU foam formulations requiring reduced emissions compliance.
