Nylon flame retardants

PA66 Retardant CR-M5575

Inovia CR-M5575 is a new halogen-free flame retardant developed for PA66. Adding about 8% can get UL94-V0 at 0.4mm. The flame retardant performance is quite stable, which is different from traditional MCA FR. The mechanical and thermal properties of the obtained PA66 flame retardant plastics remain excellent.

1. Materials
