PEEK gasket

PEEK (polyetheretherketone) is a highperformance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water. PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170oC). This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, and semiconductor.

Characteristics:
1. Excellent dimensional stability
2. Low coefficient of linear thermal expansion
3. Good mechanical properties at elevated temperatures
4. Good resistant to hot water and steam
5. Bearing grade PEEK has excellent wear characteristics
6. UL 94 V-0 flammability rating (0.059" thickness)
7. Very low smoke and toxic gas emissions when exposed to flame
8. Outstanding mechanical properties even at high temperatures
9.Optimized balance of stiffness, tensile strength and impact strength.
10.Continuous operating temperature up to + 260°C and briefly even up to +300°C

PEEK Filament Typical Applications


Used in the production of various aircraft components, PEEK reduces the overall weight of aircraft, subsequently reducing fuel consumption. As a result of its exceptional thermal properties, PEEK can also be used to protect sensitive devices from heat generated by the jet engines. With such durability, combining PEEK with FFF printing will result in lower operating and manufacturing costs.
