PEEK (Polyether ether ketone )

PEEK, also known as polyether, is a high-performance engineering thermoplastic. PEEK is a fantastic lightweight alternative to most soft metals in applications involving high stress and high temperature.

The substance is highly durable and resistant to wear and resistant to abrasion. PEEK, with a melting point of 343°C, can withstand high temperatures: it can be used continuously up to 250°C in hot water or steam without permanent loss of physical properties.

Glass-filled PEEK is a high-performance plastic with high rigidity, strength, and toughness. Even in hostile thermal and chemical environments, its capacity to maintain dimensional stability is improved by including glass fibers. This material is frequently used in the aerospace, automotive, medical, chemical, semiconductor, and microwave industries.

PEEK plastic is usually divided into two categories: industrial and medical.

Features of PEEK:

  • Corrosion resistance, anti-aging
  • Anti-dissolution
  • Both toughness and rigidity
  • High-temperature resistance
  • Good wear resistance, antistatic and electrical insulation performance
  • High strength

Applications of PEEK Plastics

It has been widely used in automotive manufacturing, aerospace, electrical and electronic, medical and food processing, and other industries.

In the aerospace, automotive, chemical, electronics, and energy industries, industrial-grade PEEK plastic is used, whereas medical-grade PEEK plastic is used in healthcare and dentistry.

Automotive

The market’s increased use of PEEK resin, especially in the auto parts market, is the fastest, particularly in engine parts, transmission parts, steering parts, and so on., which use PEEK plastics instead of some traditional expensive metals as manufacturing materials. PEEK resin demand will increase as the automotive industry adapts to miniaturization, lightweight, and cost reduction. A European model has 44 parts that use PEEK plastic instead of traditional metal products.

Medical Instruments

PEEK can be used to create dental descaling devices and endoscope parts for medical equipment because it can resist repeated autoclaving. Additionally, because of its high strength and low dissolution, PEEK has been employed in liquid chromatography columns, tubes, accessories, etc. Furthermore, because PEEK is biocompatible with the human body, it has successfully replaced titanium metal as an artificial bone material.

Office Machinery Parts

Special heat-resistant bearings, chains, gears, and so on are used for the separation claws. Because PEEK resin is used instead of metal as their material, the parts can be lightweight, fatigue-resistant, and oil-free.
