MATERIAL GUIDE
PEEK
CF30 / GF30 / ESD / Lubriloy®
We specialize in PEEK machining — custom CNC machining of PEEK and filled PEEK grades (CF30, GF30, ESD, Lubriloy®) for applications that demand strength, heat resistance and chemical stability.
Key Properties
High strength and stiffness
Continuous service to 260°C (500°F)
Excellent chemical resistance
Low wear and low friction
ESD and lubricated grades available
Typical Applications
Seal rings and bushings
Semiconductor wafer handling parts
Pump and valve components
Electrical insulators
Medical instrument parts
Machining Capabilities
PEEK is machined on CNC mills and lathes to tight tolerances. We offer prototypes and production runs, with dimensional inspection before shipping.
FAQ
Q: Can you machine filled PEEK grades?
A: Yes — CF30, GF30, ESD (static dissipative) and Lubriloy® (lubricated) grades are available.
Q: What is the continuous service temperature of PEEK?
A: 260°C (500°F) for unfilled PEEK; filled grades may vary.
