PEEK (Polyether Ether Ketone) is a high-performance thermoplastic polymer that is known for its exceptional mechanical, thermal, and chemical properties. Here are some of the key properties of PEEK:
- High Resistance at High Temperatures: PEEK has excellent thermal stability and can withstand high temperatures up to 260°C (500°F) without losing its mechanical properties. This property makes it a suitable material for high-temperature applications in industries such as aerospace, automotive, and electronics.
- Biocompatibility: PEEK is a biocompatible material that is commonly used in medical and dental applications such as implantable devices, orthopedic implants, and dental implants. Its biocompatibility is due to its inertness and resistance to degradation in the human body.
- Resistance to Ultra-High Vacuum: PEEK is also known for its high resistance to ultra-high vacuum environments. Its low outgassing rate makes it a suitable material for use in space and vacuum applications, where contamination is a concern.
- Exceptional Chemical Resistance: PEEK has excellent resistance to a wide range of chemicals, including acids, bases, solvents, and fuels. Its chemical resistance makes it a suitable material for use in harsh chemical environments, such as chemical processing and oil and gas industries.
- High Strength and Stiffness: PEEK has a high strength-to-weight ratio, making it stronger and stiffer than many other thermoplastics. This property makes it a suitable material for high-stress applications, such as aerospace and automotive parts.
- Excellent Electrical Properties: PEEK has excellent electrical properties, including high dielectric strength, low dielectric constant, and low dissipation factor. These properties make it a suitable material for electrical and electronics applications, such as connectors and insulators.
