Carlock Sealing's XPU is a specialized, ultra-high hardness polyurethane with a rating of Shore A 97. It is specifically engineered to handle extreme pressures where standard polyurethanes fail, yet it retains the elastic memory that PTFE lacks. In many high-pressure hydraulic applications, XPU serves as a superior, cost-effective alternative to PTFE, providing a better seal with significantly easier installation and zero mold fees.
High-hardness polyurethane material with outstanding physical properties and excellent wear resistance. Due to its excellent anti-extrusion performance, it is very suitable for the production of sliding rings. It also meets the needs of engineering plastic components with high elastic recovery rates and can be used under high pressure and extrusion gap conditions.
- Extreme Extrusion Resistance: Shore A 97 hardness allows XPU to withstand high-pressure peaks without the need for additional back-up rings in many cases.
- Cost-Effective Solution: Offers the performance of high-end plastics at the price point of a premium elastomer, reducing overall maintenance costs.
- Simplified Installation: Unlike rigid PTFE, XPU is flexible enough to be installed into closed grooves, reducing assembly time and the risk of seal damage.
- Superior Sealing Integrity: Combines the wear resistance of PU with the stiffness of engineering plastics, ensuring zero leakage in heavy-duty cycles.
Technical Disclaimer: XPU is a high-performance alternative to PTFE but has a lower temperature limit (up to 110°C) and different chemical compatibility. Carlock Sealing recommends consulting our technical team to ensure XPU is suitable for your specific pressure, temperature, and media requirements.
FAQ:
Q: Can XPU really replace PTFE seals?
A: In many high-pressure hydraulic applications below 110°C, Carlock Sealing's XPU is an excellent replacement. It offers similar extrusion resistance but provides a better "seal" because it is more elastic and conforms better to the hardware.
Q: Is XPU difficult to install compared to standard PU?
A: While it is harder than standard 95 Shore A PU, XPU is still an elastomer. It can be snapped into grooves that would require split-designs or special tools for PTFE, making it much more user-friendly.
