Ketron Peek Rod | Plastic Stockist

Ketron Peek Rod (natural/brownish grey or black)

A unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making it the most popular advanced engineering material. Available in Ketron PEEK 1000, Ketron Peek HPV, Ketron Peek GF30 and Peek CA30 grades in Rod.

Ketron Peek Rod is often used to replace PTFE when higher mechanical load bearing capacity, or when superior wear resistance is needed. Ketron Peek Rod is widely selected as a replacement for metal components. Examples of components made from Ketron 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 Rod

Ketron Peek rod typical applications are Valve Seat, Dosing Valves and Pump Wear rings. Below are some examples on why Peek plastic was chosen for the applications.

Peek valve seat was adopted due to premature replacement of a glass-filled PTFE seat, causing 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 was an ideal choice for this filling operation. During the process, 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 offers the requested chemical resistance against foodstuffs and cleaning agents, as well as excellent wear resistance and dimensional stability. Ketron Peek offers a food contact compliant composition in line with the EU & US regulatory requirements. The benefits with using Peek plastic are the part lifetime is increased and maintenance significantly reduced. Furthermore, Ketron Peek is easily machined.

Ketron Peek Pump Wear Rings replaced the original bronze parts. The bronze parts shipped with the original units were changed to Ketron Peek CA30 parts instead as the centrifugal pump wear parts were failing due to corrosion and galling. 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.
