Gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of pipelines. Gaskets are usually divided into ordinary rubber gaskets and oil resistant asbestos rubber gaskets, suitable for sealing water, water vapor, oil, solvents, medium acids, and alkalis, and applied in sealing of medium and low pressure connections. PEEK (Polyether Ether Ketone) is a semi crystalline thermoplastic with excellent chemical corrosion resistance, high temperature stability, and hydrolysis resistance, making it a rising star in the gasket industry and highly favored.
The reason why PEEK (polyetheretherketone) material gaskets can stand out is inseparable from their excellent performance.
PEEK has unique strength and stiffness, and can still remain unchanged under high-intensity compression.
PEEK has the heat resistance of thermosetting plastics, with a long-term use temperature of about 260-280 ℃ and a short-term use temperature of up to 330 ℃. It can also withstand high pressure up to 30MPa and maintain dimensional stability.
PEEK has excellent resistance to chemical corrosion, whether it is oil stains or strong acids or alkalis, it can remain unchanged and is a good material for high-temperature sealing rings.
PEEK also has good formability of thermoplastic materials.
In recent years, PEEK thrust pads have been widely used in the automotive manufacturing industry for transmission systems, which can maintain stable and continuous operation in high temperature environments. Compared with metal materials, they have low creep, oil and corrosion resistance, and are more economical for mass production due to their thermoplastic nature.
