Thixotropic jelly for fiber optic cable
- Satisfaction guarantee
- Fast delivery
- Quality assurance
Description
Application:
Thixotropic jelly is a water-blocking compound specifically designed for filling optical fiber cable loose tubes at high line speeds.
Features:
It is a non-sticky, silicon-free water-blocking filling compound. It remains soft at -50 ºC and does not drip at 80 ºC.
It is thixotropic and suitable for cold filling process. It inhibits mold growth, has extremely low hydrogen generation, zero oil separation,
and has excellent antioxidant properties and long-term stability.
