PP-400 is a water-blocking compound specifically designed for interstitial filling between ribbons, open slot optical fiber cable designs and exhibits excellent compatibility with Polypropylene



PP-400 is a soft, non-sticky hydrophobic compound, flexible to -40oC, non-draining at 80oC and thixotropic for controlled filling at ambient temperature. PP-400 is non nutritive to fungus, exhibits low hydrogen generation, zero oil separation with excellent resistance to oxidation for long-term stability. 400-PP also offers excellent compatibility with the matrix used in ribbon fiber.

Filling Compound For Optical Fiber Cable


PP-400 is compatible with most cable grade polymers including Polypropylene. 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.



PP-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.
