Working with PEEK-ESD ESD-COND

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.

PEEK-ESD ESD-COND — frequently asked

What is PEEK-ESD ESD-COND used for?

PEEK-ESD ESD-COND 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 ESD-COND?

PEEK-ESD ESD-COND has a typical yield strength of 88 MPa (12.8 ksi) and a tensile strength of 72 MPa (10.4 ksi) — stronger than 90% of polymer grades. Strength varies by condition: see the 6 listed tempers.

Is PEEK-ESD ESD-COND easy to machine?

Reasonably — machinability is rated good (55/100, worse than 64% 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 ESD-COND 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 ESD-COND?

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 ESD-COND?

PEEK-ESD ESD-COND is rated for continuous use to about 250°C (482 °F), and briefly to 310°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
