The
Ketron PEEK family of materials is based on the polyetheretherketone
resin. This semi-crystalline advanced materials exhibits
a unique combination of high mechanical properties,
temperature resistance and excellent chemical resistance
making it the most popular advanced plastics material.

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 Ketron PEEK grades. The composition of the raw
materials used for the production of the Ketron PEEK-1000
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 Ketron PEEK "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.
Ketron
PEEK - TX (PEEK + solid lubricant) blue
This
new member of the Ketron PEEK family has been developed especially for the food industry. Like Ketron PEEK-1000, this new internally lubricated material has a food contact compliant composition, but offers far superior wear and frictional performance, making it especially suitable for a wide variety of bearing and wear applications in the 100 to 200°C service temperature range.
Ketron
PEEK Proven Applications
Pump wear rings
 30%
Carbon fiber-reinforced Ketron PEEK improves centrifugal pump efficiency
by permitting closer inning tolerances and eliminating corrosion, galling
and wear problems (Prior materials: Bronze)
Electrical housing
 Ketron
PEEK offers precise machinability, mechanical stability and superior electrical
insulating characteristics in this coil former that focuses an electron
beam to create detail on silicon chips. (Prior materials: Epoxy thermoset)
Bushings, bearings, seals, back up rings
 In
applications ranging from aircraft to oilfield drilling, components machined
from Ketron PEEK improve performance and reliability. ( Prior materials:
Reinforced PTFE, PPS, Bronze)
Ketron Peek Technical Notes
From 150°C onwards (above the glass transition temperature), the mechanical properties of all Ketron Peek grades drops off significantly and the coefficient of linear thermal expansion increases considerably. Consequently, a material like Torlon* PAI would be better suited for close tolerance parts operating under high loads at temperatures over 150°C.
Like most reinforced materials, Ketron Peek-HPV, Ketron Peek GF30, Ketron Peek CA30 and Ketron Peek TX exhibits a moderate toughness and impact strength. Therefore, all "imternal" corners of parts made from these materials should be radiused (R> 1mm) and edges chamfered to maximise part toughness.
