Polyetheretherketone (PEEK) is a high-performance engineering thermoplastic that offers a unique combination of properties. PEEK is known for its high-temperature resistance, excellent chemical resistance, and outstanding mechanical properties. This material is commonly used in applications that require high strength and rigidity at elevated temperatures.
PEEK is resistant to a wide range of solvents and radiation, and it has very low moisture absorption. Its exceptional wear and abrasion resistance make it suitable for demanding environments, including those with high temperatures and exposure to steam or hot water.
Due to its superior properties, PEEK is often chosen as a high-strength alternative to fluoropolymers in hostile environments. It is frequently used in industries such as automotive, aerospace, medical, oil and gas, and electronics.
