High-Activity Blowing Catalyst for Optimal Flow and Cell Expansion

MXC-5 (Pentamethyldiethylenetriamine, PMDETA) is a highly active, high-purity liquid tertiary amine. Specifically designed as a powerful blowing catalyst, it offers extraordinary selectivity for the water-isocyanate reaction, making it the premier choice for manufacturing low-density rigid insulation, pour-in-place appliances, and high-resilience (HR) flexible molded foams
Molecular Architecture & Targeted Blowing Catalysis

The fundamental tridentate molecular structure of MXC-5 is engineered to maximize gas generation and optimize foam expansion:
Tridentate Amine Architecture: Featuring three highly active nitrogen centers within its C9H23N3 structure, it delivers intense catalytic power even at minimal dosage levels (e.g., 1.5 php in MDI systems).
FHighly Selective CO_2 Generation: It exhibits a strong, targeted preference for the water-isocyanate (blowing) reaction over the gelling reaction. This guarantees rapid, uniform carbon dioxide gas generation, which is essential for creating flawless, low-density cellular structures.
Exceptional Flowability & Structural Integrity
For production managers handling complex molds or large appliance cavities, MXC-5 resolves critical processing bottlenecks during the initial expansion phase:
Superior Liquid Flowability: It drastically improves the flow characteristics of the reacting polyurethane mixture. This ensures the expanding foam smoothly reaches every intricate corner of the mold before premature curing occurs.
Density Reduction: By accelerating the blowing phase, it allows factories to efficiently lower the overall foam density without sacrificing the dimensional stability or compressive strength of the rigid panels.
Process Versatility & Factory Reliability
We maintain rigorous manufacturing standards to ensure MXC-5 integrates seamlessly into your automated production lines across various foam systems:
Broad System Compatibility: While highly effective in MDI-based appliance systems, it also performs flawlessly across TDI and TDI/MDI blends for HR flexible molded foams, microcellular elastomers, and integral skin applications.
Guaranteed High Purity: A strict minimum purity of 98.5% ensures predictable reaction kinetics, eliminating the risk of batch-to-batch variations.
Strict Moisture Control: Maintained at a water content of $< 0.5\%$, it prevents unwanted side reactions and formulation spoilage during storage, securing your supply chain stability.
