2-HYDROXYPROPYLTRIMETHYLAMMONIUM FORMATE TMR-2 POLYURETHANE CATALYST
URL: /2-hydroxypropyltrimethylammonium-formate-tmr-2-polyurethane-catalyst
Product Summary
2-Hydroxypropyltrimethylammonium formate (CAS 62314-25-4) is a quaternary ammonium salt specifically formulated as a polyurethane catalyst. Marketed as TMR-2, it is a trimerization catalyst that promotes the formation of isocyanurate structures in polyurethane foam, enhancing thermal stability and flame retardancy. Ideal for rigid foam applications in construction, appliances, and insulation.
Key Selling Points
- Highly Active Trimerization Catalyst: General amine value ≥160 mgKOH/g ensures strong catalytic activity for efficient isocyanurate formation, leading to foam with improved dimensional stability and heat resistance.
- Low Acid Value for Consistent Performance: Acid value ≤20 mgKOH/g minimizes side reactions, providing predictable processing and consistent foam properties.
- Controlled Moisture Content: Water ≤2% prevents premature reactions and ensures stable foam density and cell structure.
- Good Color Stability: Color ≤100 APHA maintains product clarity, reducing potential discoloration in foam applications.
- Blendable Raw Materials: Made from PO, TMA, and formic acid, it is compatible with standard polyurethane formulations.
- ISO-Certified Production: Produced by a factory with ISO 9001, ISO 14001, and ISO 45001 certifications, ensuring quality and reliability.

Models and Options
This product is available under the model TMR-2, which is a standard trimerization catalyst. Custom packaging options can be arranged upon request.
Materials and Structure
The catalyst is synthesized using propylene oxide (PO, CAS 75-56-9), trimethylamine (TMA, CAS 75-50-3), and formic acid (CAS 64-18-6). The resulting quaternary ammonium salt features a hydroxypropyltrimethylammonium cation paired with a formate anion, which is key to its catalytic activity in polyurethane foam.
Applications
TMR-2 is widely used in the production of rigid polyurethane foams for:
- Construction insulation panels
- Refrigeration and cold storage
- Pipe insulation
- Household appliance insulation
- Exterior wall insulation
