Core Features

1. Excellent thixotropy: Its viscosity decreases under shear stirring with good fluidity, facilitating pouring and filling on production lines. It quickly reverts to a gel state at rest, resisting dripping and flowing at high temperatures and avoiding hardening at low temperatures, ensuring long-term retention inside the cable core.

2. Dual functions of water blocking and buffering: It fills the gaps between the cable core and loose tubes to physically block the longitudinal penetration of moisture. The gel provides elastic buffering to absorb compression and vibration impacts, reduce optical fiber microbending loss and protect optical fibers.

3. Stable performance over a wide temperature range: The normal operating temperature range is -40℃ to 80℃. It does not crack or harden at low temperatures, and no oil separation or delamination occurs at high temperatures. It features strong oxidation resistance and is resistant to aging during long-term service in buried and pipeline environments.

4. Chemical inertness and low hydrogen evolution: It has a low acid value and stable chemical properties. Its low hydrogen evolution property prevents hydrogen-induced damage to optical fibers. It shows good compatibility with all optical cable materials including optical fiber coating, PBT loose tubes, FRP, PP binding tapes and metal armoring, without corroding or swelling other components.

5. Insulation, mildew and microorganism resistance: It possesses favorable electrical insulation performance. It can inhibit the growth of mold and microorganisms, maintaining stable performance for a long time in humid soil and underground pipeline environments.
