Product Profile:
- 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 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. Click on each for more product information.
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.
Proven Applications:
Pump Wear Rings
Ketron® PEEK CA30 improves centrifugal pump efficiency by permitting closer running tolerances and eliminating corrosion, galling and wear problems. (Prior material: Bronze) |
 |
|
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) |
 |
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)
