High Temperature Resistance: PEEK can operate continuously at temperatures up to 260°C (500°F) without losing its mechanical strength, making it suitable for extreme environments.

Chemical Resistance: It is highly resistant to aggressive chemicals, including acids, bases, and solvents, which allows its use in harsh chemical environments.

Mechanical Strength: PEEK retains excellent mechanical properties under high temperatures and pressure, providing durability and reliability in critical applications.

Wear Resistance: Its excellent wear resistance makes PEEK ideal for use in applications involving friction and movement, such as bearings and seals.

Low Smoke and Toxic Gas Emissions: PEEK produces very low levels of smoke and toxic gases when exposed to fire, making it safe for use in confined or sensitive environments.

Lightweight: PEEK is lighter than metals but can offer comparable strength, which is beneficial in applications requiring weight reduction.

Aerospace: PEEK is used in components that require high strength, light weight, and resistance to extreme temperatures and chemicals.

Automotive: It is used in engine components, transmission parts, and other high-performance automotive parts due to its high temperature and chemical resistance.

Medical: PEEK is biocompatible, making it suitable for implants and medical devices such as spinal implants and dental components.

Electronics: PEEK is used in insulation, connectors, and other electronic components that need to withstand high temperatures and chemicals.

Chemical Processing: PEEK components such as pumps, valves, and seals are used in environments involving aggressive chemicals and high pressures.
