Polyamide Flame Retardant - MCA-50



Phoniton MCA-50 is a kind of high effective nitrogen halogen free flame retardant. It is very stable when the temperature is lower than 300℃. However, sublimation will happen when the temperature is above 350℃. The decomposition temperature of MCA-50 is 440℃~450℃. MCA-50 is in high content of nitrogen, it will release N₂, CO₂ and water while burning. The flame retardancy takes effect through absorbing heat and releasing incombustible gases after sublimation and  decomposition. 


MCA-50 is especially suitable for PA6 and PA66 without filler. PA6 and PA66 with MCA-50 can pass the tests of UL 94 V-0(0.75mm), GWFI 960℃ and GWIT 750℃.
