PEEK - Polyetheretherketone For Dummies. AKA, For The BeginnerAmerican Made Plastics

***

Why use PEEK:

  • it has Excellent Chemical Resistance
  • has Extremely High Continuous Temperature – to 480ºF
  • is Outstanding Wear Resistance and Low Moisture Absorption
  • has Good Dimensional Stability

PEEK - Polyetheretherketone For Experts

*This materials is…

an excellent machining material – a favorite of machinists. Works like a soft brass, and has exceptional dimensional stability.

  • Excellent Machining
  • Low co-efficient of Friction / Superior Wear Resistance
  • Dimensionally stable
  • Very low moisture resistance
  • Outstanding Wear Resistance and Excellent Dimensional Stability
  • Is USP Class VI approved – upon factory request (per batch)

PEEK is a highly crystalline thermoplastic with excellent properties making it an ideal material for medical, electrical and electronic industries. Also makes great pump, compressor, valve seat, and housing applications. Rated as ‘Best’ or nearly the best in all mechanical properties of plastic materials. It carries UL 94-V-0 flammability rating and is FDA approved for food contact.
VICTREX® is the leading supplier of this specialty resin. This range of materials also includes: Avaspire PAEK and PEKK grades which offer similar but improved property ranges in either impact, heat or stress applications.

Some popular applications are:

  • Steam Valves, Seals and Equipment
  • Semi-Conductor Machine Components
  • Autoclave applications – Resists Hydrolysis Under Super Heated Steam/Water
  • Chemical Pump Gears and Wear Plates
  • Medical, Surgical and Aerospace parts
  • High Temperature Insulation, Bearings and Rollers
  • Plasma Arc Torch Bodies

Contact us for more information on all the other grades in the Ketone family. While it solves many demanding engineering requirements, it is also rather expensive. Most clients choose these resins as a last resort, but if your design calls for high heat, high chemical resistance, excellent dimensional stability, excellent wear resistance and/or USP certification, these are an excellent solution. VICTREX® has been at the forefront of high performance plastic materials, with PEEK being their flag-ship product line. Mil-P-46183 is most common specification associated with PEEK, call for additional information.
