PEEK, or Polyether Ether Ketone, is a high-performance thermoplastic known for its excellent mechanical properties, 

chemical resistance, and high temperature resistance. Since it was first commercialized by Victrex in the UK in 1978, 

PEEK has been widely used and developed in many fields due to its unique properties. PEEK is a linear aromatic 

semi-crystalline polymer with a very high melting point (about 343°C) and glass transition temperature (about 143°C).

 It not only has good mechanical strength and toughness, but also maintains its physical properties such as corrosion 

resistance, fatigue resistance, and low friction coefficient in extreme environments. These properties make PEEK an 

ideal engineering material for manufacturing parts that need to withstand high temperature, high pressure, and high 

wear environments.

Applications

1. Aerospace industry: PEEK is widely used in aircraft internal structural parts, fasteners, and engine components due 

to its light weight, high strength, and corrosion resistance.

2. Medical industry: PEEK is often used to make artificial joints, spinal implants and other medical devices because 

of its good biocompatibility with human tissue and its elastic modulus similar to that of bone.

3. Automobile manufacturing industry: PEEK can be used to produce engine peripheral parts, brake system components 

and interior parts to reduce weight and improve fuel efficiency.

4. Electronic and electrical industry: With its excellent insulation performance and heat resistance, PEEK is used as 

connectors, switches and circuit board supports.

5. Chemical industry: In strong acid and alkali environments, PEEK can work stably for a long time and is suitable for 

the manufacture of equipment such as pumps, valves and seals.

In recent years, with the development of the global economy and the advancement of technology, the demand for 

high-performance materials has increased, and the PEEK market has also shown a steady upward trend. Especially in 

the aerospace, medical and automotive industries, the application of PEEK has continued to expand, driving the rapid 

development of the market. According to the latest market research report, the global PEEK market is expected to reach 

billions of dollars by 2025. Among them, the Asia-Pacific region will become one of the fastest growing markets, mainly 

due to the rapid economic development and accelerated industrialization process in China, India and other countries. 

At the same time, the European and North American markets will continue to maintain a steady growth trend due to their 

high technological maturity and wide application areas. In the future, with the improvement of production processes and 

the reduction of raw material costs, PEEK is expected to be popularized in more fields and further expand its market share.
