At present, the PEEK on the market is mainly Victrex, as well as Evonik, Solvay and some domestic materials.

The material has an extremely high temperature (about 260 degrees Celsius) and has extremely high stiffness and hardness, as well as unique high tensile strength and fatigue strength. In addition, it has excellent heat resistance and chemical stability. When the temperature reaches 260 degrees Celsius, the material has excellent dielectric properties and is resistant to energy radiation.

PEEK has excellent comprehensive properties, good mechanical properties, high temperature resistance, and superior chemical resistance, making it the most versatile high-grade plastic.

Characteristics: The maximum allowable working temperature in the air is very high (can work continuously at 260 degrees, up to 310 degrees in a short time), high mechanical strength, rigidity and hardness, high temperature resistance, excellent chemical resistance and hydrolysis resistance, excellent wear and friction resistance, extremely high creep strength, excellent dimensional stability, outstanding ultraviolet resistance, excellent high-energy radiation resistance, inherent low flammability, and less smoke production during combustion.

Applications: PEEK is very commonly used in the aerospace, medical, pharmaceutical and food processing industries, such as gas analyzer structures on satellites, heat exchanger wiper blades; Because of its superior friction properties, it has become an ideal material in friction applications, such as sleeve bearings, plain bearings, valve seats, sealing rings, pump wear rings, etc.

PEEK is a high-temperature-resistant, high-performance thermoplastic special engineering plastic. It has good mechanical properties and resistance to chemicals, wear, hydrolysis and other properties; It has light specific gravity, good self-lubricating performance, and can be filled with carbon fiber, molybdenum disulfide, etc. to further improve lubrication performance and mechanical strength due to its very good processing performance. The broad application space of PEEK engineering plastics involves aviation, machinery, electronics, chemical industry, automobile and other high-tech industrial fields, and can manufacture high-demand mechanical parts, such as gears, bearings, piston rings, support rings, sealing rings (letters), valve plates, wear rings, etc.

The excellent performance of PEEK material is mainly manifested in the following aspects:

1.High temperature resistance.

PEEK has a high glass transition temperature and melting point (334), which is one of the reasons why it can be used reliably in applications where heat resistance is required. Its load thermal deformation temperature is up to 316 °C, and the continuous use temperature is 260 °C.

2.Mechanical properties.

PEEK is a plastic that balances toughness and rigidity. In particular, its excellent fatigue resistance to alternating stresses is the most outstanding of all plastics and is comparable to that of alloy materials.

3.Self-lubrication.

PEEK has excellent sliding properties among all plastics, making it suitable for applications where a low coefficient of friction and abrasion resistance are critical. In particular, carbon fiber and graphite each account for a certain proportion of mixed modified PEEK self-lubrication performance is better.

4.Chemical resistance (corrosion resistance).

PEEK has excellent chemical resistance, in the usual chemicals, only concentrated sulfuric acid can dissolve or destroy it, and its corrosion resistance is similar to that of nickel steel.

5.Flame retardant.

PEEK is a very stable polymer with thick samples and can meet the highest flame retardant standards without the addition of any flame retardants.

6.Peel resistance.

PEEK has a good peel resistance, so it can be made into very thin wires or magnet wires and can be used under harsh conditions.

7.Fatigue resistance.

PEEK has the best fatigue resistance of all resins.

8.Radiation resistance.

The ability to resist radiation is very strong, surpassing the best radiation resistance of polystyrene among general-purpose resins. It can be made into high-performance wires that maintain good insulation ability even at irradiation doses of up to 1100 mrad.

9.Hydrolysis resistance.

PEEK and its composites are not chemically affected by water and high-pressure water vapor, and products made of this material can maintain excellent properties when used continuously in high-temperature and high-pressure water.

PEEK is a kind of special engineering plastic, a special engineering plastic synthesized by the British ICI company in 1977. The word PEEK has been registered with Victrex for special engineering plastics, so the name of this material varies greatly from country to country. Because PEEK has excellent performance, as netizens best adopted and said, it is widely used in aerospace, automobile, pump and valve, petroleum, chemical and other industries.

Because it is non-toxic, it is also the best material for making human bones. PEEK has excellent performance and can be used in many different fields due to its flexible design and processing. Finished products include profiles, injection molding, compression molding, films, coatings and other forms.
