MXFR-TCPP

MXFR-TCPP is a cornerstone halogenated phosphorus-based flame retardant (FR) widely utilized in the polyurethane (PU) industry. For technical engineers and factory procurement teams, the chemical efficacy of this additive lies in its phosphorus-chlorine synergy, which provides robust fire suppression through both gas-phase and condensed-phase mechanisms. The phosphorous content (min. 9.4%) acts as a char-forming agent, creating a protective barrier that inhibits heat transfer, while the chlorine content (min. 32.4%) releases halogen radicals to quench the flame.

One of the most critical operational benefits of MXFR-TCPP is its low viscosity (60-70 CPS at 25°C). This low-viscosity profile is essential for high-pressure dosing systems and automated production lines, as it ensures thorough mixing with polyol blends without requiring significant pre-heating or causing excessive pump wear. Furthermore, its high decomposition point (min. 200°C) ensures that the flame retardant does not volatilize or degrade during the exothermic reaction of PU foam formation, particularly in high-density rigid board and spray insulation.

From a quality assurance perspective, MXFR-TCPP demonstrates excellent hydrolysis stability, which is vital for the long-term aging performance of insulation materials. Its low acid value (max. 0.05%) and extremely low water content (max. 0.05%) prevent interference with the delicate isocyanate-water-catalyst balance, ensuring that the final foam maintains consistent cell structure and dimensional stability. By integrating MXFR-TCPP into flexible or rigid systems, manufacturers can achieve stringent fire safety compliance while maintaining the mechanical integrity and thermal resistance of their finished products.
