Product Introduction:
HF-400B 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. HF-400B can make the materials
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.
