PEEK - Polyetheretherketone 

TECAPEEK Ensinger Plastics

PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining. It is extruded in sheet, rod and tube that may use Victrex® PEEK 450G or Solvay KetaSpire® KT-820 polymer. PEEK is a unique semi crystalline, engineering thermoplastic that also offers excellent chemical compatibility.

Parts manufactured from high temperature plastic PEEK polymer can also operate at temperatures up to 260°C (480°F) and have a melting point around 341°C (646°F). PEEK plastic is often used in hot water or steam environments because it maintains physical properties such as flexural and tensile strength at a high level despite the severe environment. Polyetheretherketone is often viewed as one of the engineering thermoplastics that tends to command a high price, however experienced users have come to realise the added value that PEEK materials bring by offering the possibility of manufactured parts that are lighter, stronger and able to survive longer periods under harsh conditions.


Decades of expertise

We have 3 decades of experience in the field of PEEK extrusion, and were in fact one of the first companies to ever extrude PEEK successfully. Over the years we have developed a distribution network with more than 20 subsidiaries, and are supplying PEEK all over the world. 

Huge portfolio

As one of the largest PEEK manufacturers in the world, Ensinger is able to provide a comprehensive portfolio of stock shapes via several different manufacturing processes. In addition to our standard PEEK natural, we also offer several grades for specific industries such as medical, semiconductor, electronics and mechanical engineering. Furthermore, we offer an exceptionally broad range of dimensions for PEEK plates, PEEK rods and PEEK tubes.

Custom size products

In order to meet individual processing requirements of a designed component, we offer various finishing options, such as cutting and planing, or grinding and fabrication. These operations can add value to the user by bringing you closer to your final part configuration, thus, saving time and resources.

properties and characteristics of PEEK

PEEK polymer is a high performance plastic material with an excellent balance of physical properties. It has one of the highest levels of heat resistance and mechanical strength available among plastics. It is also one of the best choices when looking for good chemical resistance, as well as radiation resistance. Click on the list below for detailed PEEK characteristics.

Extensive product range - more than 50 peek variations

Ensinger is a manufacturer of various PEEK modifications. All PEEK plastics are supplied as:
  • PEEK rod
  • PEEK sheet and plate
  • PEEK tube

Metal replacement with TECAPEEK natural inside a carbon fiber composite robotic arm

In high speed moving components, saving weight is crucial to reducing inertia and improving efficiency. In this case study, a composite robotic arm used for high-speed picking and handling Delta Robots was enhanced by replacing a metal insert with TECAPEEK natural high performance thermoplastic material.
