Properties and Uses of PEEK (Polyetheretherketone)

In the ever-evolving world of manufacturing, the quest for materials that blend strength, versatility, and durability has been relentless. One such material that has risen to the occasion and left an indelible mark in various industries is Polyetheretherketone, or simply, PEEK. As Plastic Service Centers, your trusted partner in high-performance plastics, we're excited to take you on a journey to explore the incredible properties and myriad applications of PEEK.

The Power of PEEK

PEEK, short for Polyetheretherketone, is a high-performance thermoplastic polymer known for its exceptional mechanical, thermal, and chemical properties. It's no wonder that PEEK has become the material of choice for manufacturers across a wide range of industries.

Outstanding Mechanical Properties

PEEK boasts a remarkable combination of high tensile strength, excellent stiffness, and superior fatigue resistance. This makes it an ideal candidate for applications where mechanical integrity is paramount. Whether it's in the aerospace sector for lightweight yet sturdy components, automotive manufacturing for engine components, or medical devices requiring strength and biocompatibility, PEEK shines.

Exceptional Thermal Stability

Another standout feature of PEEK is its outstanding thermal stability. With a melting point of around 343°C (649°F), PEEK can endure high-temperature environments without losing its mechanical properties. This property is invaluable in applications such as seals, gaskets, and electrical components in demanding conditions.

Chemical Resistance

PEEK's resistance to a wide range of chemicals, including acids and organic solvents, sets it apart from many other plastics. This makes it an excellent choice for chemical processing equipment, where exposure to aggressive substances is commonplace.

Insulating Properties

In the electrical and electronics industry, PEEK is prized for its electrical insulating properties. It provides excellent dielectric strength, making it an essential material for various electrical components, connectors, and insulators.


The medical and pharmaceutical sectors have embraced PEEK due to its biocompatibility. It's used in medical implants, dental instruments, and various medical device components.

The Versatility of PEEK

PEEK's versatility extends across a spectrum of industries:

  • Aerospace: PEEK's lightweight and high-performance characteristics make it a go-to choice for aircraft components.
  • Oil & Gas: Its resistance to high temperatures and harsh chemicals makes it indispensable in downhole and subsea applications.
  • Automotive: PEEK finds its place in engine components, transmission parts, and more.
  • Semiconductor: Its excellent electrical insulating properties are highly valued in cleanroom environments.
  • Food Processing: PEEK's FDA-compliant grades are used in machinery and equipment for food and beverage processing.
