Carlock Sealing's 40% Bronze filled PTFE is the premier choice for high-demand hydraulic and mechanical applications. By reinforcing Virgin PTFE with a high percentage of bronze powder, we dramatically increase the material's compressive strength and thermal conductivity. This compound is specifically engineered by Carlock Sealing to resist extrusion and wear under extreme pressures where pure PTFE would fail.
- Maximum Extrusion Resistance: 40% Bronze reinforcement provides the highest load-bearing capacity among PTFE compounds.
- Enhanced Heat Dissipation: Improved thermal conductivity prevents localized overheating at the sealing interface during high-speed motion.
- Minimal Wear & Friction: Offers an ideal balance of durability and low friction for long-stroke hydraulic cylinders.
- Dimensional Stability: Significantly reduced "cold flow" (creep) ensures consistent sealing performance under constant heavy load.
Disclaimer: The addition of 40% Bronze increases the material's weight and alters its chemical resistance profile compared to Virgin PTFE. This material is conductive and may not be suitable for applications requiring electrical insulation. Carlock Sealing recommends consulting our technical team for high-acid or food-grade applications.
FAQ:
Q: When should I choose 40% Bronze filled PTFE over Virgin PTFE?
A: Carlock Sealing recommends 40% Bronze filled PTFE for high-pressure hydraulic applications, piston seals, and wear rings where Virgin PTFE is too soft to resist extrusion or cold flow.
Q: Is Bronze-filled PTFE compatible with all fluids?
A: While highly resistant, the bronze filler can be affected by certain corrosive chemicals (like strong acids). Carlock Sealing advises checking chemical compatibility if used outside of standard hydraulic oil environments.
Q: Does Carlock Sealing provide custom-size wear rings in this material?
A: Yes. We use precision CNC turning to manufacture custom wear rings, guide strips, and piston seals up to 4000mm in diameter with no mold fees.
