Product Introduction:
HF-401D flame retardant is a halogen-free flame retardant for PA, mainly composed of phosphorus
and nitrogen as flame retardant elements. It has excellent flame retardant properties and good thermal stability.
Compared with bromine antimony flame retardant system, it has the advantages of halogen-free
environmental protection, low smoke density and low smoke toxicity. The flame retardant grade of
polyamide flame- retarded with HF-401D 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
