XF-400

TECHNICAL DATA SHEET 

 

 Application
XF-400 is a water-blocking compound specifically designed for filling optical fiber buffer loose tubes at high line speeds.

 

Description

 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 XF-400 is non nutritive to fungus, exhibits low hydrogen generation, zero oil separation with excellent resistance to oxidation for long-term stability.


Product Name
Filling Compound For Optical Fiber Cable

 Compatibility

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.

 

Processing
POLYGEL XF-400 is suitable for cold pumping and processing enabling cable filling without voids created by compound shrinkage. A line-synchronized gel metering system is available comprising of a drum pump, de-aeration, filtration unit and a metering control unit for stable dosing of the gel.
