Identification & Functionality


Features & Benefits

Product Overview
  • Excellent chemical resistance
  • Very low moisture absorption
  • Inherently good wear and abrasion resistance
  • Unaffected by continuous exposure to hot water or steam

Ketron® PEEK grades offer chemical and hydrolysis resistance similar to PPS, but can operate at higher temperatures. PEEK 1000 offers steam and wear resistance, while carbon-reinforced PEEK provides excellent wear capabilities. Our latest grade, PEEK HPV, offers outstanding bearing performance. PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.

Applications & Uses

Product Applications
  • Structural Parts - Ketron® PEEK is used for vacuum wand handles during semiconductor manufacturing. They typically contact heat and common process chemicals in use (Prior materials: Nylon, Acetal).
  • Bushings, Bearings, Seals, Back Up Rings - In applications ranging from aircraft to oil field drilling, components machined from Ketron® PEEK improve performance and reliability (Prior materials: Reinforced PTFE, PPS, Bronze).

Technical Details & Test Data

Engineering Notes

The stiffness of all PEEK grades drops off significantly and expansion rate increases above its glass transition temperature (Tg) of 300°F (150°C). A material like Torlon* PAI would be better suited for close tolerance bearings or seals operating at temperatures higher than 300°F (150°C)

  • Thermal Properties -  The figures given for these properties are for the most part derived from raw material supplier data and other publications.
  • (2) Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI, PAI & PI). DMA settings, oscillation amplitude of 0.20 mm; a frequency of 1 Hz; heating rate of 2°C/min
  • (3) Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on the duration and the magnitude of the mechanical stresses to which the material is subjected.
  • (4) Impact strength decreasing with decreasing temperature, the minimum allowable service temperature is practically mainly determined by the extent to which the material is subjected to impact. The value given here is based on unfavorable impact conditions and may consequently not be considered as being the absolute practical limit.
  • (5) These estimated ratings, derived from raw material supplier data and other publications, are not intended to reflect hazards presented by the material under actual fire conditions. There is no ‘UL File Number’ available for these stock shapes.
  • Mechanical Properties -  Most of the figures given for the mechanical properties are average values of tests run on dry test specimens machined out of rods 40-60 mm when available, else out of plate 10-20mm. All tests are done at room temperature (23° / 73°F)
