Product Advantages
1. Ultra-Low Friction: PTFE coating reduces friction by 50% compared to standard graphite braiding.
2. Broad Chemical Resistance: PTFE protects graphite from aggressive corrosive media.
3. Self-Lubricating: Graphite and PTFE work synergistically for automatic lubrication, minimal shaft wear.
4. Anti-Stick: PTFE surface prevents material adhesion to the shaft or gland box.
5. Easy Installation: High flexibility makes it easy to install in narrow gaps or complex surfaces.
