Features Of TMG 234 Polyurethane Catalyst

  1. Highly selective tertiary amine catalyst optimized for balanced gelling and blowing reactions in flexible slabstock foams.

  2. Low volatility and reduced amine odor, supporting improved workplace safety and compliance with industrial hygiene standards.

  3. Excellent compatibility with polyether polyols and common isocyanates (e.g., TDI, MDI), ensuring stable formulation performance.

  4. Enables precise control over cream time and rise profile, facilitating consistent foam density and cell structure.

  5. Non-corrosive to processing equipment and compatible with standard metering and mixing systems.

Typical Applications Of TMG 234 Polyurethane Catalyst

  1. Flexible polyurethane slabstock foams for bedding and furniture.

  2. Automotive seating and interior trim foams requiring low-emission profiles.

  3. High-resiliency (HR) foams with enhanced comfort and durability.

  4. Conventional and water-blown molded foams for cushioning applications.

  5. Composite foam systems where co-catalyst synergy with tin-based or other amine catalysts is required.
