DFR-series are used as an INORGANIC FLAME RETARDANT  (HALOGEN-free) for a thermoplastic resins. The DFR-series are designed for having a NEW CRYSTAL STRUCTURE, therefore these have superior properties and are free from the disadvantages of the conventional Magnesium hydroxide and Aluminum trihydroxide. Also, DFR-series powder is uniform and fine, that is coated with a fatty SURFACE-TREATING AGENT for the special application.
