Features of PEEK
Mechanical Properties
PEEK is a plastic that balances both toughness and rigidity. Notably, its excellent fatigue resistance under alternating stress is the best among all plastics and is comparable to that of alloy materials.
Self-Lubricating Property
PEEK exhibits outstanding sliding properties among plastics, making it ideal for applications requiring a low coefficient of friction and high wear resistance. In particular, PEEK modified with a specific proportion of carbon fiber and graphite offers even better self-lubricating performance.
Chemical Resistance (Corrosion Resistance)
PEEK demonstrates excellent resistance to chemicals. Among commonly used chemicals, only concentrated sulfuric acid can dissolve or degrade it. Its corrosion resistance is comparable to that of nickel steel.
Flame Retardancy
PEEK is a highly stable polymer. A sample with a thickness of 1.45 mm can meet the highest flame retardant standards without the need for any added flame retardants.
Peeling Resistance
PEEK has strong resistance to peeling, allowing it to be used for thin coatings or electromagnetic wires, even in harsh environments.
Fatigue Resistance
PEEK offers the best fatigue resistance among all plastic resins.
Radiation Resistance
It has excellent resistance to high radiation levels, outperforming polystyrene (the best among general-purpose resins). PEEK can be used to produce high-performance components that maintain good insulation properties even under gamma radiation doses up to 1100 Mrad.
Hydrolysis Resistance
PEEK and its composites are chemically stable when exposed to water and high-pressure steam. Products made from PEEK retain excellent performance even after continuous use in high-temperature, high-pressure water environments.
PEEK Applications
Automobile Industry
Used in engine inner covers, automotive bearings, gaskets, seals, clutch gear rings, and other components. Also applied in rotating parts, brake systems, and air conditioning systems.
01
Aerospace
Used for wire harness clips, impeller blades, radar radomes, fairing brackets, rocket battery tanks, bolts, nuts, and components of rocket engines.
02
Mechanical and Chemical Industry
Applicable in the manufacture of chemical pumps, valves, compressor valves, piston rings, impellers, and other related components.
03
Electronics and Electrical Appliances
Used in wafer carriers, electronic insulation films, various connectors, solar energy components, cartridge products, printed circuit boards, and high-temperature connectors.
04
