PEEK Flat Washer

The PEEK flat washer is a high-performance engineering washer meticulously manufactured by JINGHONG FASTENERS using special polymer material, polyetheretherketone. This product demonstrates outstanding reliability and durability under extreme conditions such as high temperature, corrosion, high load, and electrical insulation. It covers conventional and special thread requirements from M2 to M20, meeting diverse tightening and protection needs ranging from precision microelectronics to heavy industrial equipment.

Compared to traditional metal or ordinary plastic washers, PEEK flat washers possess comprehensive characteristics including lightweight, high strength, heat stability, insulation protection, chemical corrosion resistance, self-lubrication, and dimensional stability. They have become the core auxiliary components in semiconductor, medical devices, aerospace, chemical equipment, new energy, and precision instruments, for achieving insulation isolation, corrosion prevention connections, resistance to high-temperature aging, and impact wear resistance. Their performance advantages significantly enhance the operational stability and service life of equipment in harsh environments, and are important functional components that promote modern high-end manufacturing to achieve lightweight, precision, and high reliability.

Product Feature

The PEEK flat gasket is suitable for various extreme working conditions. Its long-term operating temperature range is from -50℃ to 260℃, and it can withstand a short-term temperature of 310℃. It will not deform or soften in high-temperature environments. The product has excellent chemical stability, capable of resisting the erosion of most acids, bases, organic solvents and oils. Its anti-corrosion ability is superior to that of ordinary metals and plastics. It also has good strength, toughness and wear resistance. It can replace metal gaskets in high-load scenarios. It has a low water absorption rate and excellent insulation performance. Even in a humid environment, it can maintain a stable size and have a lasting and reliable insulation effect.
