Product Introduction:
HF-400M9B is a halogen-free flame retardant masterbatch for PA, mainly composed of high
concentration of organic hypophosphite. Compared with pure powdered flame retardants, it has less dust,
uniform feeding, high production capacity, stable production process, good thermal stability, halogen-free
environmental protection, low smoke density, low smoke toxicity, etc. The flame retardant grade of HF-
400M9B flame-retardant polyamide material can reach UL 94 V-0 (0.75mm), pass GWIT 750℃ and GWFI
960℃ glow wire test, and pass 70℃×168 hours immersion test (UL746C), and fully meet the requirements
of RoHS and REACH regulations.
