PEEK
Ketron™
PEEK grades offer chemical and hydrolisis resitance
similar to PPS, but can operate at higher temperatures.
Unreinforced PEEK offers good wear resistance, while Carbon-reinforced
PEEK provides excellent wear capabilities. PEEK can be used
continuously to 480°F (250°C) and in hot water or
steam without permenant 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 (H101)
This general purpose grade is unreinforced and offers
the highest elongation and toughness of all PEEK grades.
|
30%
Glass-reinforced Ketron™ PEEK (H301)
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
impproved strength, stiffness or stability, especially at
temperatures above 300°F (150°C).

30%
Carbon fiber-reinforced Ketron™ PEEK (H201)
The addition of carbon fibers enhances the comprehensive
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 3 1/2 times higher thermal conductivity than
unreinforced PEEK - dissipating heat from the bearing surface
faster.

Engineering
Notes:
The stifness of PEEK drops off significantly and expansion
rate increases above its glass transission 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).

Proven Applications
Pump wear rings
30% Carbon fiber-reinforced Ketron PEEK improves centrifugal
pump efficiency by permitting closer running tolerances and
eliminated corrosion, galling and wear problems. (Prior material:
Bronze)
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) |
