Extruded PEEK Tubing — also supplied as PEEK tube, PEEK capillary tubing, or extruded PEEK pipe — is made from 100% virgin polyetheretherketone resin. No fillers. No recycled content. Outer diameters range from 0.5 mm to 50 mm. Inner diameters from 0.25 mm to 40 mm. Standard length is 1000 mm; 2000 mm and cut lengths are available. Continuous operating temperature is -50 °C to 260 °C. Short‑term peak reaches 300 °C. Natural (tan) is stock colour. Black (carbon‑filled) is available on request.

Applications

  • HPLC and analytical chemistry fluid transfer lines
  • Semiconductor wafer processing fluid and gas lines
  • Medical catheter shafts and endoscopic components
  • High‑voltage electrical insulation sleeves and bushings
  • Oil and gas down‑hole sensor housings
  • Aircraft wire harness protection and thermal shield sleeving

Key Performance Data

  • Coefficient of friction 0.30–0.35 against steel, dry (ASTM D1894). No stick‑slip.
  • Tensile strength retains over 50 % of its room‑temperature value at 250 °C (ISO 527). Long‑term exposure at 260 °C causes no chemical degradation.
  • Resistant to steam, hot water, concentrated acids (except nitric), bases, and all organic solvents. No weight gain after 30 days in 37 % HCl at 80 °C.
  • UL 94 V‑0 at 1.5 mm. Limiting oxygen index 35 %. Smoke density Ds (ASTM E662, 4 min) below 0.05.
  • Dielectric strength 20 kV/mm. Volume resistivity above 10¹⁶ Ω·cm. Insulation resistance remains stable after 96 h at 40 °C / 95 % RH.
  • Low outgassing: total mass loss (ASTM E595) <0.5 %; collected volatile condensable material <0.1 %.

Certifications & Compliance

  • ISO 9001:2015 — certified quality management system.
  • RoHS (Directive 2011/65/EU) — compliant.
  • REACH (EC) 1907/2006 — PEEK polymer exempt; no SVHC above 0.1 %.
  • FDA 21 CFR 177.2415 — compliant for repeated food contact (natural grade only).
  • Third‑party test reports for tensile strength, HDT, and dielectric strength available upon request.

Packaging & Container Loading

  • Small‑diameter tubing (<6 mm) wound on spools → PE bag → corrugated box.
  • Straight lengths (≥6 mm OD) bundled in PE film → corrugated box.
  • Boxes stacked on ISPM 15 heat‑treated fumigated pallet (1.1 m × 1.1 m).
  • Max pallet gross weight: 800 kg.
  • 20GP container: approx. 10 pallets; 40HQ: approx. 20 pallets.

Quality Control

  • Incoming inspection: PEEK resin melt flow index and moisture content verified per batch.
  • In‑line monitoring: OD and wall thickness measured with laser micrometer on 10 % of tubes per shift.
  • Batch traceability: unique lot number laser‑marked on each tube. Traceable to resin lot and extrusion date.
