Melamine Cyanurate (MCA) is a nitrogen-based, halogen-free, environmentally friendly flame retardant self-assembled from melamine and cyanuric acid through hydrogen bonding. It appears as a white fine powder and features economical use, highly efficient flame retardancy, excellent electrical and mechanical properties, no discoloration, low smoke, and low corrosivity. Its flame retardant mechanism is as follows: upon heating, MCA sublimes and absorbs heat to lower the material surface temperature, while simultaneously catalyzing polymer dehydration and carbonization to form a dense intumescent carbon layer that isolates oxygen and heat, and releasing non-combustible gases such as nitrogen to dilute the concentration of combustible substances, achieving dual flame retardancy in both the condensed phase and the gas phase.<\/p>\n
The most core and mature application field of MCA is the flame retardant modification of unfilled nylon 6 and nylon 66. Adding an appropriate amount of MCA enables the material to easily meet the UL94 V-0 (1.6mm) flame retardant standard. MCA exhibits good compatibility with the nylon matrix, imparting excellent flame retardancy to the material while maximally preserving its electrical and mechanical properties, and is not prone to mold sticking, foaming, or exudation. In glass fiber reinforced nylon systems, MCA can likewise achieve gas-phase flame barrier through its own endothermic decomposition and the generation of non-combustible gases.<\/p>\n
Beyond nylon, the application landscape of MCA has expanded to multiple fields. In rubber, MCA can be compounded with synergists such as aluminum hypophosphite for halogen-free flame retardant modification of EPDM rubber. In fire retardant coatings, MCA can be added as a flame retardant and matting auxiliary, significantly reducing the smoke density of coatings during combustion. In thermoplastic elastomers (TPE), MCA is increasingly widely used due to its environmental friendliness and substrate compatibility advantages. In addition, MCA is also widely used in materials such as polyurethane, phenolic resin, epoxy resin, acrylic emulsion, polyethylene, and polypropylene.<\/p>\n
Dongguan Hongtaiji Flame Retardant Materials Co., Ltd. has been deeply engaged in the research and development of environmentally friendly flame retardants for more than 20 years. The particle size of its independently developed nano-scale MCA can be finely controlled to 400\u2013600nm. The high specific surface area resulting from nanonization increases the catalytic charring efficiency by 40%. Adding 8\u201312% in PA6\/PA66 can achieve UL94 V-0 grade. The products are widely used in high-end fields such as lithium battery separator coatings, high-end nylon spinning, electronic and electrical components, automotive parts, and ultra-thin flexible copper clad laminates, and comply with the ROHS Directive and REACH regulation standards.<\/p>","protected":false},"excerpt":{"rendered":"
