High-temperature resistance (up to 260°C)
PEEK does not lose its mechanical strength and dimensional properties at steady-state operating temperatures that go up to 260°C.
It is not easy to soften and deform it, which explains why it is perfect for environments where there is a lot of exposure to heat.
Applications are engine parts, high-heat industrial equipment, tools, and sterilizable medical equipment.
Excellent strength-to-weight ratio
Despite its being a lightweight material, PEEK possesses the same tensile strength as certain metals.
Its strength-to-weight advantage permits a lower material consumption and lighter assemblies.
This is popular in the aerospace and automotive industries, with minimal weight, giving efficiency and performance.
High chemical resistance
PEEK withstands a wide variety of chemicals, in particular, acids, bases, and organic solvents, even under high temperatures.
This guarantees high durability and reliability under severe chemical processing conditions or for biomedical uses.
It is great for seals, gaskets, valves, and lab equipment, which come under the influence of aggressive substances.
Low dielectric constant (electrical insulation)
PEEK is a good electrical insulator with stability over the range of frequencies and temperatures.
It has low dielectric loss, making it an appropriate material for high-performance applications in electronics and aerospace industries.
You will find it in connectors, cable insulations, and in sensitive electrical housings.
Biocompatible and FDA-approved (medical-grade)
Medical-grade PEEK is non-toxic and can be compatible with human body tissue; it is not harmful for implants and surgical instruments.
It is capable of withstanding sterilization cycles (steam, gamma, or EtO) without degrading.
Sanctioned by the FDA and in compliance with the ISO 10993, it is commonly employed in orthopedic, dental, and spinal implants.
