Filling Compound for Optical Fiber Cable
XF-400 is specifically designed for optical fiber loose tube at high line speeds. Its best working temperature is room temperature, with the temperature rises, its viscosity will gradually decrease.
XF-400 is silica free, soft, non-sticky hydrophobic compound. It can remain soft at -50℃,and doesn’t drip at 80℃. It is thixotropic,suitable for cold filling. It can inhibit the growth of mold, very low hydrogen evolution, zero oil separation , with excellent oxidation resistance and long-term stability .
