KETRON®
PEEK /
VICTREX® PEEK™ |
The KETRON PEEK family of materials is based on polyether-etherketone
resin. This semi-crystalline advanced material exhibits a unique
combination of high mechanical properties, temperature
resistance and excellent chemical resistance, making it the most
popular advanced plastics material.
Main characteristics:
- very high max. allowable service temperature in air
(250°C continuously, up to 310°C for short periods)
high mechanical strength, stiffness and creep
resistance, also at elevated temperatures
excellent chemical and hydrolysis resistance
excellent wear and frictional behaviour (particularly
KETRON PEEK-HPV and PEEK-CA30)
very good dimensional stability
inherent low flammability and very low levels of smoke
evolution during combustion
good electrical insulating and dielectric properties
(except for KETRON PEEK-HPV and PEEK-CA30)
excellent resistance against high energy radiation

KETRON PEEK-1000 stock shapes are produced from virgin
polyetheretherketone resin and offer the highest toughness and
impact strength of all KETRON PEEK grades. Both KETRON PEEK-1000
natural & black can be sterilized by all conventional
sterilization methods (steam, dry heat, ethylene oxide and gamma
irradiation). Additionally, the composition of the raw materials
used for the manufacture of KETRON PEEK-1000 stock shapes
complies with the regulations of the European Union (Directive
2002/72/EC, as amended) and the United States of America (FDA)
for plastic materials and articles intended to come into contact
with foodstuffs.

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.

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.

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.

Important note: up to the 18th June 2010 we had the statement
that "all four KETRON® PEEK grades are based on VICTREX® PEEK
polymers" on this page of our site. We purchase KETRON® PEEK
products from Quadrant EPP. Earlier in June 2010, we placed an
order with Quadrant EPP (UK) Ltd for KETRON® PEEK LSG rod. In
addition to the standard certificate of conformity which comes
with the LSG grade, our customer requested a statement that the
rod had been extruded using VICTREX® PEEK 450G. The Order
acknowledgement we received stated that the rods to be supplied
would be manufactured from VICTREX® PEEK 450G but this could not
be guaranteed to be the case for future purchases of this
product. We sort clarification from Quadrant EPP’s UK sales
office.
This is their response received on the 11th June; “All KETRON®
Peek 1000 Grade Material previously supplied to yourselves has
been manufactured from VICTREX® 450G Resins. Moving forward, due
to supply risk management we cannot have only one resin
supplier. If we do use another resin supplier this resin will be
thoroughly tested and certified before being introduced into the
market and will be of equivalent if not superior quality. Our
material will be supplied as per our Data sheet which has not
been changed. We reserve the right to use the relevant resins to
ensure the quality of our KETRON® PEEK 1000.”
Engineering & Design Plastics Ltd have not put into stock any
KETRON® PEEK between the 11th and 18th of June 2010 and to avoid
confusion, all existing stock will be labeled VITREX® PEEK 450G.
In future, when we order KETRON® PEEK from Quadrant we will be
requesting clarification as to the manufacture of that
particular batch and the product will be labeled accordingly
before it enters our stock. We will be monitoring the situation
and if Quadrant EPP are unable to supply the products our
customer's wish to purchase, we do have other suppliers that can
currently guarantee that their products are manufactured, solely
from VITREX® 450G polymers.
