Core Features

1. Rapid swelling upon contact with water for longitudinal water blocking. When exposed to moisture, the superabsorbent resin on the surface quickly absorbs water and swells to form a dense gel, filling the gaps in the cable core. It prevents water from spreading longitudinally along the optical cable and protects optical fibers from water erosion and freeze damage; the gel is stable and not prone to leakage.

2. Excellent mechanical properties suitable for high-speed cabling. The base material is high-strength polyester filament, featuring high tensile strength, minimal powder shedding and low fuzz. It boasts good thermal stability and can withstand the short-term high temperature during sheath extrusion. The yarn will not easily break during cabling winding.

3. Dry and clean without grease contamination. It contains no grease and is cleaner compared with grease filling. No grease cleaning is required during optical cable joint construction. It reduces the weight of optical cables and facilitates processing and subsequent operation and maintenance.

4. Good chemical compatibility with neutral and non-corrosive property. It has a neutral pH value and will not corrode optical fibers, loose tubes, FRP strength members, PP binding tapes and other optical cable components. It is acid and alkali resistant, mildew-proof and anti-microbial aging, maintaining stable performance under long-term buried and humid environments.
