Ketron PEEK (Polyetheretherketone) is a type of organic polymer thermoplastic that is utilized in various engineering applications. It is recognized as a very advanced type of plastic, and its frictional and wear behavior is considered to be outstanding, even when compared to other advanced plastics.
Ketron is available in different grades, but overall the features you can expect from this particular thermoplastic include:
- Exceptionally high maximum allowable service temperature in air (482° F for continuous periods of time and as much as 590° F for short periods of time)
- Superb hydrolysis and chemical resistance
- Remarkable wear and frictional behavior
- Great dimensional stability
- High creep resistance, mechanical strength, and stiffness, even when exposed to high temperatures
- Incredibly resistant to X-rays, gamma rays and other high energy radiation
- Inherent low flammability and minimal levels of smoke evolution when combustion occurs
As for the different Ketron grades, they are as follows:
PEEK 1000 – Unreinforced material that delivers the highest level of toughness and elongation of all the grades, and is utilized in instrument components where appearance is important (i.e. vacuum wand handles).
PEEK GF30 – 30% glass reinforced, this grade offers better stiffness and strength at higher temperatures.
PEEK CA30 – 30% carbon reinforced, it enhances the compressive stiffness and strength of the Ketron material.
PEEK LSG – This is the life science grade that has been purposely developed for applications related to life science with the intention of saving money and time within this particular industry.
PEEK TX – This features an internally lubricated material that has a composition that is food contact compliant, and provides far superior frictional and wear performance.
PEEK HPV – This is the bearing grade and has the lowest coefficient of friction and is especially suited for friction and wear applications.
As you can see, Ketron is a highly versatile and useful advanced group of plastics.
