Typical Case1:Carbon fiber reinforced PEEK gear
✅PEEK 880CA30 is Suitable for manufacturing gears, compared to metal gears, its weight is significantly reduced, making it suitable for high-speed operation and requiring frequent closing or stopping.
✅Secondly, it has lower noise and excellent shock absorption performance
Typical Case2:Carbon fiber reinforced PEEK Valve
✅ Corrosion resistant and medium resistant
Can be exposed to acids, alkalis, solvents, and vapors for a long time, unlike metal valve plates that are prone to corrosion or require surface treatment.
✅ Oil free self-lubricating+low wear
When paired with metal valve cores/bodies, it has low friction, is not easy to bite, and has a long service life, making it suitable for oil free/difficult to lubricate systems.
✅ Lightweight+anti creep
The density is only about 1.4, reducing the load on the valve stem/spring; Carbon fiber makes it less prone to permanent deformation under long-term pressure and provides better sealing reliability.
