Properties of PEEK

High-Temperature Stability: PEEK exhibits excellent thermal stability, retaining its properties at high temperatures. Its melting point is around 343 degrees C, and it can continuously operate at temperatures up to 260 degrees C.

Mechanical Strength: This material is known for its high mechanical properties, such as stiffness, strength, and toughness, which it maintains even under stressful conditions.

Chemical Resistance: PEEK is resistant to a wide range of chemicals, including organic and inorganic substances. Its robustness extends to resistance against hydrolysis, even against superheated steam.

Wear Resistance: PEEK exhibits excellent wear resistance in both standard and demanding applications.

Fire Resistance: Due to its aromatic structure, PEEK is inherently flame retardant.

The unique combination of properties makes PEEK a material of choice in a wide range of industrial applications. Below are some noteworthy applications.

Aerospace: Due to its excellent strength-to-weight ratio, PEEK is often used in the aerospace industry for components such as seals, gears, and bearings.

Medical: Its excellent biocompatibility and ability to be sterilized make PEEK an excellent choice for medical implants and surgical instruments.

Electronics: PEEK’s electrical properties and flame resistance are critical in the production of cable insulation, connectors, and semiconductors.

Automotive: In the automotive industry, PEEK is used for parts such as pistons, valves, and bearings, contributing to weight reduction and fuel efficiency.

Oil and Gas: PEEK’s high temperature and chemical resistance properties make it suitable for seals, compressor rings, and other components in the oil and gas industry.
