MAIN CHARACTERISTICS
* Very high max. allowable service temperature in air
(250°C continuously going up to 310°C for short periods)
* High mechanical strength, stiffness and hardness, also at elevated temperatures
* Excellent chemical and hydrolysis resistance
* Excellent wear & frictional behaviour
(particulary 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 KETRON PEEK-CA30)
* Excellent resistance against high energy radiation (gamma and X-rays)
KETRON PEEK-GF30 natural (brownish grey) [PEEK - GF30]
This 30% glass fibre reinforced grade offers a higher stiffness and creep resistance than KETRON PEEK-1000 and has a much better dimensional stability. This grade is ideal for structural applications supporting high static loads for long periods of time at elevated temperatures. The suitability of KETRON PEEK-GF30 for sliding parts, however, is to be carefully examined since the glass fibres tend to abrade the mating surface.
