PEEK 990CA30
PRES
PEEK CF30 rods are extruded PEEK bars reinforced with 30% carbon fiber, delivering tensile strength up to 260 MPa, flexural modulus up to 24 GPa, and continuous service at 260 °C. They provide the highest stiffness, exceptional wear resistance in the PEEK family.
Flexural modulus 23–24 GPa — 3× stiffer than unfilled PEEK. Minimal deflection under high load.
Dry friction coefficient 0.28. Outperforms metals in unlubricated, high-speed bearing applications.
Volume resistivity ~10⁴ Ω·cm. Safely dissipates static in semiconductor and electronics handling.
Low CLTE and 4× higher thermal conductivity than virgin PEEK for precision-machined parts.
Our standard length is 1000mm,we can cut into the length as your need,the stardard diameter is 6-200mm,if you need bigger diameter we can custom for you.
FDA / USP Class VI compliance is required
Maximum chemical purity is critical
Easiest CNC machinability is preferred
Electrical insulation is required
Cost is a primary constraint
Moderate stiffness is sufficient
Maximum stiffness & wear resistance are required
ESD-safe performance is mandatory
Metal replacement is the design goal

Use PCD (polycrystalline diamond) tooling for production. Carbon fiber is highly abrasive and will rapidly dull carbide or HSS tools.
Use compressed air only. Liquid coolant causes moisture absorption and dimensional instability.
Anneal machined parts at 150 °C for 2 hours, followed by slow cooling, to eliminate residual stress.
