Product Introduction
SF-850 is a phosphorus-based flame retardant synergist with a high decomposition temperature. When added to materials, it exhibits excellent thermal stability, good compatibility, and no blooming. It demonstrates outstanding synergistic effects with bromine-antimony systems, significantly enhancing the Glow Wire Ignition Temperature (GWIT) of the materials.
When 8% SF-850 is added as a synergist to bromine-antimony flame-retardant glass fiber reinforced PBT, the material can pass the GWIT test at 850℃/(2.5~3.0mm).
