Ketron Peek
Ketron Peek (natural/brownish grey or black)
A unique combination of high mechanical properties, temperature
resistance and excellent chemical resistance making it the most popular
advanced plastics material. Available in PEEK 1000, HPV, GF30 and CA30
grades in sheet & rod.
Ketron Peek is often used to replace PTFE when higher mechanical load
bearing capacity, or when superior wear resistance is needed. Ketron Peek
is widely selected as a replacement for metal components. Examples of
components made from PEEK grades: pump components, valve seats, bearings,
rollers, gears, high temperature insulators, components exposed to boiling
water or steam.
Ketron PEEK-1000 (PEEK) natural (brownish grey) / black
Ketron PEEK-1000 stock shapes are produced from virgin
polyetheretherketone resin and offer the highest toughness and impact
strength of all grades. The composition of the raw materials used for the
production of the natural stock shapes complies with the directives of the
European Union and the American FDA regulations concerning plastic
materials intended to come into contact with foodstuffs. These features,
added to its excellent sterilisability by means of steam, dry heat,
ethylene oxide and gamma irradiation, make this grade very popular in
medical, pharmaceutical and food processing industries.
Ketron PEEK-HPV (PEEK + CF + PTFE + graphite) black
The addition of carbon fibres, PTFE and graphite to virgin PEEK results
in a "Bearing Grade". Its excellent tribological properties (low friction,
long wear and high Pressure-Velocity capabilities) make this grade
especially suited for bearing and wear applications.
Ketron PEEK-GF30 (PEEK-GF30) natural (brownish grey)
This 30% glass fibre reinforced grade offers higher stiffness and creep
resistance than Ketron PEEK-1000 and has a much better dimensional
stability. Ketron PEEK-GF30 is very appropriate for structural parts
carrying high static loads for long periods of time at elevated
temperatures. Its suitability for sliding parts, however, is to be carefully
examined since the glass fibres tend to abrade the mating surface.
Ketron PEEK-CA30 (PEEK-CF30) black
This 30% carbon fibre reinforced grade combines even higher stiffness,
mechanical strength and creep resistance than Ketron PEEK-GF30 with an
optimum wear resistance. Moreover, the carbon fibres provide 3.5 times
higher thermal conductivity than virgin PEEK, dissipating heat from the
bearing surface faster.
Common Uses for Ketron Peek
Ketron Peek Valve Seat
Premature replacement of a glass-filled PTFE seat caused excessive warranty
expense for a manufacture of industrial cleaning equipment. The solution
was to use Ketron Peek 1000 to replace the poppet seat and allowed increased
reliability of the mixing unit in the cleaning equipment. Hydrolysis
resistant and far more stable than PTFE, Ketron Peek 1000 retains its
properties after thousand of hours of operation.
Ketron Peek Dosing Valves
During the filling operation, viscous liquids are pressed through these
valves and dosed directly into the single portion packages. Designers were
looking for a material that offered chemical resistance and dimensional
stability. Food contact compliance was also needed. Ketron Peek 1000
offers the requested chemical resistance against foodstuffs and cleaning
agents, as well as excellent wear resistance and dimensional stability.
Ketron Peek 1000 offers a food contact compliant composition in line with
the EU & US regulatory requirements. The benefits with using Peek 1000 are
the part lifetime is increased and maintenance significantly reduced.
Furthermore, Ketron Peek 1000 is easily machined.
Ketron Peek Pump Wear Rings
Centrifugal pump wear parts were failing due to corrosion and galling. The
bronze parts shipped with the original units were replaced with Ketron Peek
CA30 parts. The Peek rings eliminated the problem and increased the
efficiency of the units. The chemical resistance, temperature resistance
and good stability of the carbon fibre filled PEEK CA30 form the ideal
material for high temperature, close tolerance applications where chemicals
are present.
