Working with PEEK-ESD CF30-ESD
Is PEEK-ESD easy to machine?
Machines like unfilled PEEK but the carbon filler is abrasive — use polished-flute carbide or PCD tooling, sharp positive rake, high speed/low feed, air or clean coolant, and stress-relieve thick stock before finish cuts.
Can PEEK-ESD be welded?
Hot-plate, ultrasonic, IR and spin welding work with reduced joint strength; laser transmission welding is impossible because the part is opaque black — mechanical fastening or adhesive bonding after plasma treatment is common.
Can PEEK-ESD be formed, bent or molded?
Inject at 370–400 °C melt with 180–200 °C mold and slow decompression to keep the conductive network intact; hot runners and high shear can break carbon-black/CNT chains and raise resistivity, so gate and screw design are checked against target Ω/sq.
What surface finishes work on PEEK-ESD?
Cannot be plated or painted usefully in ESD service; specify machined or bead-blasted matte surfaces, deburr carefully to avoid loose carbon particles, and verify surface resistivity per ANSI/ESD STM11.11 after any surface treatment.

What is PEEK-ESD CF30-ESD used for?
PEEK-ESD CF30-ESD is typically used for wafer handling components, electronics fixtures, ESD-safe tooling and cleanroom parts. In short: controlled surface resistivity; cleanroom-compatible PEEK; opaque black only.
What is the yield strength of PEEK-ESD CF30-ESD?
PEEK-ESD CF30-ESD has a typical yield strength of 180 MPa (26.1 ksi) and a tensile strength of 185 MPa (26.8 ksi) — stronger than 100% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is PEEK-ESD CF30-ESD easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 78% of polymer grades). Machines like unfilled PEEK but the carbon filler is abrasive — use polished-flute carbide or PCD tooling, sharp positive rake, high speed/low feed, air or clean coolant, and stress-relieve thick stock before finish cuts.
Can PEEK-ESD CF30-ESD be welded?
With care — weldability is rated fair (40/100). Hot-plate, ultrasonic, IR and spin welding work with reduced joint strength; laser transmission welding is impossible because the part is opaque black — mechanical fastening or adhesive bonding after plasma treatment is common.
What surface finishes work on PEEK-ESD CF30-ESD?
Cannot be plated or painted usefully in ESD service; specify machined or bead-blasted matte surfaces, deburr carefully to avoid loose carbon particles, and verify surface resistivity per ANSI/ESD STM11.11 after any surface treatment.

Inject at 370–400 °C melt with 180–200 °C mold and slow decompression to keep the conductive network intact; hot runners and high shear can break carbon-black/CNT chains and raise resistivity, so gate and screw design are checked against target Ω/sq.
What is the maximum service temperature of PEEK-ESD CF30-ESD?
PEEK-ESD CF30-ESD is rated for continuous use to about 260°C (500 °F), and briefly to 310°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
