Inovia CR-M5575 is a new halogen-free flame retardant developed for PA66. Adding about 8% would reach UL94 V0 at 0.4mm. The flame retarding performance is quite stable, which is different from traditional MCA. And the impact strength property of the obtained PA66 is obviously improved, compared to similar products on the market.
