What are the properties of PEEK?

PEEK (Polyetheretherketone) is a high-performance thermoplastic polymer known for its superior mechanical and thermal properties. It is widely used in aerospace, automotive, medical, and industrial applications due to its remarkable durability and versatility.

1. High Temperature Resistance

PEEK has an exceptional ability to withstand high temperatures, with a continuous service temperature of up to 250°C (482°F). This makes it ideal for applications that involve exposure to heat, such as engine components and aerospace parts.

2. Mechanical Strength

PEEK exhibits excellent mechanical properties, including high tensile strength, stiffness, and impact resistance. It maintains its strength and shape under stress, making it a preferred material for demanding structural applications.

3. Chemical Resistance

PEEK is resistant to a broad range of chemicals, including acids, bases, solvents, and hydrocarbons. This makes it suitable for use in aggressive chemical environments, such as in the chemical processing, pharmaceutical, and food industries.

4. Wear and Abrasion Resistance

With its low friction coefficient and high wear resistance, PEEK is commonly used in applications involving moving parts, such as bearings, gears, and seals, where longevity and minimal maintenance are crucial.

5. Electrical Insulation

PEEK offers excellent electrical insulation properties, making it useful in electrical and electronic applications, including insulators, connectors, and cables.

6. Biocompatibility

PEEK is biocompatible, meaning it is safe for use in medical implants and devices, such as spinal fusion implants and dental components. It is not harmful to human tissues and can withstand the body’s physiological conditions.

In conclusion, PEEK’s combination of high temperature resistance, mechanical strength, chemical resistance, wear resistance, electrical insulation, and biocompatibility makes it one of the most advanced and versatile engineering plastics available t
