Ketron® PEEK-GF30
Brand: 
- Extremely high maximum operating temperature in air
- High mechanical strength, creep resistance and stiffness, even at elevated temperatures
- Excellent chemical and hydrolysis resistance
- Excellent behaviour under wear and friction
- Low intrinsic flammability and extremely low emission of fumes during combustion
Interested in this product?
This grade, which is reinforced with 30% fibreglass, offers greater stiffness, dimensional stability, and creep resistance than KETRON® PEEK-1000.
It is the ideal material for structural applications intended to support heavy static loads for long periods of time at high
temperatures.
The adaptability of KETRON® PEEK-GF30 to moving parts, however, must be tested thoroughly as the fibreglass in the material tends to abrade the contact parts.
