Ketron® PEEK

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.

Ketron® PEEK 1000

This general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. The newly available black PEEK 1000 is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important.

    Ketron® PEEK GF30 (30% Glass-Reinforced)

    The addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness or stability, especially at temperatures above 300°F (150°C).

      Ketron® PEEK CA30 (30% Carbon Fiber-Reinforced)

      The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides more thermal conductivity than unreinforced PEEK -- increasing heat dissipation from bearing surfaces improving bearing life and capability.

          Ketron® PEEK CA30 improves centrifugal pump efficiency by permitting closer running tolerances and eliminating corrosion, galling and wear problems. (Prior material: Bronze)

        Ketron® PEEK LSG (Life Science Grade) Family of Products

        This series of PEEK materials were developed specifically for Life Sciences applications and are pre-qualified biocompatible materials, helping to save precious time and money.  Approved for both the United States Pharmacopeias (USP) and ISO 10993-1 by successfully passing a series of biocompability tests these products are implantable for up to 24 hours with Ketron PEEK CLASSIX up to 30 days.  

          Ketron® PEEK IM

          Injection Molded Ketron® PEEK advanced polymers shapes are ideal for machined back-up rings and v-seals.  Ketron® PEEK offers excellent chemical and wear resistance across a broad range of operating temperatures.  In addition to the widely used Ketron 1000 PEEK grade, several specific grades are available that incorporate glass or carbon fibers, or wear resistant additives that increase the wear life of machined parts.

          • Unfilled Ketron 1000 PEEK performs to 320F (160C)
          • Excellent chemical resistance
          • Excellent combination of thermal resistance and high compressive strength
          • 30% glass fiber filled and 30% carbon fiber filled grades are available
          • Injection molded shapes for thin-wall rings, extruded rods and sheets for machined parts, compression molded tubes, rods and sheets for heavier cross-section parts

          Ketron® PEEK HPV (Bearing Grade)

          Carbon fiber reinforced with graphite and PTFE lubricants, our newest grade of PEEK offers the lowest coefficient of friction and the best machinability for all PEEK grades. An excellent combination of low friction, low wear, high LPV, low mating part wear and easy machining, make it ideal for aggressive service bearings.

          Product Details

          The new PEEK metal detectable material is best suited for applications where high line speeds require good wear resistance, or where operating temperatures in use are higher than 130 °C. Further key characteristics:

          • Good material solution for machine parts which undergo multiple sterilization, mainly in equipment with CIP (cleaning in place) or SIP (sterilisation in place)
          • Suitable for food approved parts requiring high stiffness without reinforcement
          • High dimensional stability for high precision parts
          • Good impact/stiffness ratio
          • Color blue

          Materials & Processing

          • Wide range of high temperature operating materials
          • NORSOK M-710 and ISO 23926 compliance

          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)
