PEEK is a high-temperature thermoplastic, with a high glass transition temperature (143℃) and melting point (334℃), load thermal deformation temperature up to 316℃(30% glass fiber or carbon fiber reinforced), can be durable utilization at 250℃, compared with other high-temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., The upper limit of service temperature exceeds about 50℃.
Main application areas of PEEK
The automotive (including aviation) transportation market accounted for about
50% of PEEK resin consumption, semiconductor manufacturing equipment accounted
for 20%, general machinery parts products such as compressor valves accounted
for 20%, and other markets such as medical equipment and analytical instruments
accounted for 10%.
1. Transportation machinery, such as automobiles
The growth of PEEK resin in The European market is especially rapid in the
automotive parts market, especially in the parts around the engine, transmission
parts, steering parts and so on, PEEK plastic is used instead of some
traditional high-priced metals as manufacturing materials. Demand for PEEK resin
will continue to grow as the automotive industry ADAPTS to miniaturization,
lightweight, and cost reduction requirements. One European model uses PEEK
plastic instead of metal for 44 parts.
2. IT manufacturing industry
Semiconductor manufacturing and the electronic appliance industry are
expected to be another growth point for PEEK resin application. In the
semiconductor industry, in order to achieve high function and low cost, the size
of silicon chip is required to be larger, and the manufacturing technology is
more advanced. Low dust, low gas release, low ion dissolution and low water
absorption are the special requirements for various equipment materials in the
semiconductor manufacturing process, which will be the place where PEEK resin
will show its talent.
3, office machinery parts field
For separation claws, special heat-resistant bearings, chains, gears, etc. of
photocopiers, PEEK resin can be used instead of metal as their material to make
parts lightweight, fatigue resistant, and oil-free lubrication.
4. Wire covering the field
PEEK coating has excellent flame retardant, without any flame retardant, its
flame retardant class can reach UL94 V-0. PEEK resin also has peel resistance,
irradiation resistance (109 rad) and other advantages, so it is used in special
wires and nuclear-related fields.
5, plate, bar, and other fields
In the application process of PEEK in some special fields, it often meets the
phenomenon of less quantity and more varieties, so it is very advantageous to
use bars, plates and other profiles for mechanical processing and
6. Fiber field
PEEK fiber (including monofilament) industrial press cloth, industrial brush
products. In the field of composite materials, PEEK fiber's appeal lies in its
thermoplastic and high temperature resistance. In addition to the heat
resistance of industrial press cloth and industrial brush, its charm also lies
in its chemical resistance and wear resistance.
7. Medical analytical devices
Because PEEK is resistant to repeated autoclaving, it can be used in medical
devices to manufacture endoscope parts, dental descaling devices, etc. In
addition, PEEK has been used in instrumental analysis of liquid chromatography
columns, tubes, accessories, etc., due to its high strength and low solubility.
PEEK has successfully replaced titanium as an artificial bone material because
of its good compatibility with the human body.
