Product name
optical fiber cable filling compound
Feature:
XF-400 is silica free, soft, non-sticky hydrophobic compound, flexible down to 50°C, non-draining at 80°C and thixotropic for controlled filling at ambient temperature.
POLYGEL 400N-SF is non nutritive to fungus, exhibits low hydrogen generation, zero oil separation with excellent resistance to oxidation for long-term stability.
POLYGEL XF-400 is compatible with most cable grade polymers. Tests on typical acrylate coated optical fiber shows no reaction
but it is recommended that compatibility tests are made with all materials likely to come into contact with the gel.
Application
XF-400 is a water-blocking compound specifically designed for filling optical fiber buffer loose tubes at high line speeds.
