Overview :

PEEK (polyether ether ketone) is a semi-crystalline thermoplastic. As a special polymer material, PEEK has high temperature resistance and good chemical resistance, excellent electrical properties, and flame retardant ( UL94 V-0). PEEK maintains its excellent dimensional stability and good mechanical properties in a long time under high temperature steam environment.  The good comprehensive performance of PEEK makes it possible to replace traditional materials such as metals and ceramics in some fields to improve the comprehensive performance of products, and make the products lighter. PEEK can be used to a wide range of applications such as: high-precision aircraft parts, auto parts, and bearings in the industrial field, gaskets, sealing rings, surgical instruments in the medical field, extrusion into sheets and bars, etc. Shop for PEEK Rods & Sheets >>. All of our products are proven to be perfectly compliant with FDA, REACH and RoHS safety regulatory, and so on. If you need, you can contact us to check the relevant documents.

PEEK Material Applications

PEEK polymer is now used globally in industries ranging from aerospace, automotive, oil and gas, fiber optics, alternative energy, to medical. Thought of as one of the best performing materials, this relative newcomer to the thermoplastics industry can be extruded, injection molded, or used as a coating.

Automobile Industry



These are just a few examples of the extensive range of applications for Polyether Ether Ketone (PEEK). Its unique combination of properties makes it a preferred choice in industries that require high-performance materials to withstand challenging environments and demanding conditions.


What Is Polyether Ether Ketone?

Polyether Ether Ketone, commonly known as PEEK, is a top-tier thermoplastic polymer categorized under polyaryletherketones. PEEK is a high-performance, semi-crystalline thermoplastic renowned for its remarkable resistance to high temperatures, chemicals, wear, and creep, as well as its exceptional strength. It falls within the broader category of polyaryletherketone (PAEK) polymers, including variants like polyether ketone (PEK), polyether ether ketone ketone (PEEKK), and polyether ketone ketone (PEKK). However, PEEK is the most well-known polymer among variants.


What Is the Difference Between Polyether Ether Ketone (PEEK) and Polyether Ketone (PEK)?

Both PEEK and PEK belong to the polyaryletherketone family and offer high-performance properties. The main difference lies in their specific chemical structures and the presence of the "ether ether" linkage in PEEK.


What Are the advantages and Disadvantages of Polyether Ether Ketone (PEEK) in Plastic Injection Molding?

Polyether Ether Ketone (PEEK) offers exceptional properties for plastic injection molding applications, its advantages are countered by its higher cost, processing challenges, and some limitations in terms of color options and surface finish. Careful consideration of these factors is crucial when deciding whether to use PEEK in injection molding projects.


Is PEEK safe in the body?

Polyether Ether Ketone (PEEK) is considered to be safe for use in the human body. PEEK's biocompatibility makes it suitable for a range of medical and healthcare applications, including implants, surgical instruments, spinal devices, and dental components. It has been extensively used in orthopedic, spinal, and dental surgeries, among others.

What Are the Grades of Polyether Ether Ketone (Peek)?

Polyether Ether Ketone (PEEK) is available in various grades, each tailored to specific applications and requirements. Here are some common grades of PEEK: Unfilled PEEK, 30% glass filled PEEK, 30% carbon filled PEEK, Bearing grade PEEK (also known as PTFE PEEK, carbon fiber-reinforced with graphite PEEK, Ketron® HPV, etc.)


How much does PEEK plastic cost?

PEEK plastic price per pound is generally higher than other high-temperature thermoplastics but it also offers benefits that other resins lack.


Are you manufacturer or trading company?

We are integral part of industry and trade. Both the agency of some products, but also a factory for product development and production.


About bulk order leading time?

It will take about 15~30 working days from order confirmation to production completion. Specific communication can be coordinated to the time acceptable to both side.
