PEEK seals: a well-deserved all-rounder

PEEK seals stand out with high performance, play an important role in aerospace, automotive, chemical and other fields, high temperature, corrosion and wear resistance, the future to high performance, lightweight, customized development, a broad prospect.

In the modern industrial field, a variety of seals play a vital role, they ensure the normal operation of the equipment and prevent leakage and failure. Among the many sealing materials, PEEK (polyether ether ketone) seals stand out for their excellent performance and have become a worthy all-rounder. Next, let us explore the PEEK seals in different areas of the big role.

I. Performance Advantages of PEEK Seals

PEEK is a high-performance special engineering plastics, with excellent mechanical properties, high temperature resistance, chemical resistance, wear resistance and self-lubricating properties. These excellent properties make PEEK seals in a variety of harsh working environments can maintain a good sealing effect.

Outstanding Mechanical Properties

PEEK has high strength, high rigidity and good toughness, and its tensile strength, bending strength and impact strength are much higher than general engineering plastics. This makes PEEK seals able to withstand greater pressure and impact, not easy to deformation and rupture.

For example, in high-pressure hydraulic systems, PEEK seals are able to maintain sealing performance under pressures of up to thousands of pounds, ensuring the safe operation of the system.

Excellent High Temperature Resistance

PEEK has a long term service temperature of 260°C and a short term service temperature of 300°C or more. This high-temperature resistance allows PEEK seals to maintain good sealing performance in high-temperature environments, such as aerospace and automotive engines, without softening, deforming, or losing elasticity due to high temperatures.

Good Chemical Resistance

PEEK has good resistance to most chemicals, including strong acids, strong bases, and organic solvents. This makes PEEK seals in the chemical industry, petrochemical industry and other fields can resist the erosion of various corrosive media, to extend the service life of the seal.

For example, at the piping connections in chemical plants, PEEK seals can effectively prevent the leakage of chemical substances and protect the environment and the safety of personnel.

Excellent wear resistance

PEEK has a low coefficient of friction and good abrasion resistance, and is able to maintain good performance under prolonged friction and wear conditions. This enables PEEK seals to effectively reduce wear and improve sealing reliability in equipment that requires frequent movement and friction, such as valves and pumps.

Self-lubrication

PEEK itself has a certain degree of self-lubrication, without the need to add additional lubricants, reducing the contamination of the lubricant on the working medium, but also reduces the maintenance costs.

Second, PEEK seals in the aerospace field applications

The aerospace industry requires a high level of performance from its components, as any small failure can lead to serious consequences, and PEEK seals play an important role in the aerospace industry.

Engine Seals

The working environment inside the aviation engine is extremely harsh, with high temperature, high pressure and strong corrosiveness. PEEK seals can effectively seal various interfaces and connections of the engine in such an environment, preventing the leakage of fuel, lubricating oil and gas and ensuring the normal operation of the engine.

Hydraulic system sealing

The hydraulic system of an aircraft needs to work under high pressure and high temperature conditions, PEEK seals can withstand pressures up to thousands of pounds, while maintaining good sealing performance at high temperatures to ensure the stable operation of the hydraulic system.

Fuel System Seals

The sealing of the fuel system is critical to the safety of aircraft, PEEK seals can resist fuel corrosion, ensure the sealing of the fuel system, prevent fuel leakage and cause fire and other dangerous situations.

Third, the application of PEEK seals in the automotive industry

With the continuous development of the automobile industry, the performance requirements of the parts are getting higher and higher, PEEK seals have a wide range of applications in the automobile field.

Engine parts sealing

Automobile engine will produce high temperature and high pressure when working, PEEK seals can be used for engine valve oil seals, cylinder gasket and other parts of the seal, to improve the performance and reliability of the engine.

Transmission Seal

The complex working environment inside the transmission requires seals that can withstand high speed rotation and high temperature, PEEK seals can meet the sealing requirements of the transmission and extend the service life of the transmission with their excellent performance.

Battery Sealing for New Energy Vehicles

In new energy vehicles, the sealing of the battery is very important, PEEK seals can effectively prevent the electrolyte inside the battery from leaking, to ensure the safety and service life of the battery.

Application of PEEK seals in chemical industry

Chemical industry involves a variety of corrosive media and high temperature and high pressure working conditions, the requirements for seals are very harsh, PEEK seals in the chemical industry applications mainly include the following aspects:

Pipeline sealing

The medium transported in the chemical pipeline is often highly corrosive and toxic, PEEK seals can ensure that the pipeline connections are sealed reliably, to prevent the leakage of the medium caused by environmental pollution and safety accidents.

Reactor sealing

Reaction kettle plays a key role in chemical production, need to work in high temperature, high pressure and strong corrosive environment, PEEK seals can provide good sealing performance for the reaction kettle, to ensure the smooth progress of the production process.

Valve sealing

Chemical valves need to be opened and closed frequently, which requires high abrasion and corrosion resistance of the sealing ring, PEEK seals can meet the sealing requirements of the valve and improve the service life and reliability of the valve.

Fifth, PEEK seals in the field of electrical and electronic applications

In the electrical and electronic field, PEEK seals also have unique application value.

Connector sealing

Connectors in electronic equipment need good sealing performance to prevent dust, moisture, etc. from entering and affecting the normal operation of the equipment, PEEK seals can provide reliable sealing to protect the performance of the connector.

Transformer Sealing

Transformer will generate heat when working, need good heat dissipation and sealing, PEEK seals can ensure the sealing at the same time, has good thermal conductivity, help transformer heat dissipation.

Sixth, PEEK seals in the medical field applications

The medical industry requires high biocompatibility and safety of materials, PEEK seals also have certain applications in the medical field.

Medical equipment sealing

Such as medical syringes, infusion pumps and other equipment, the need for seals to ensure that the liquid leakage-free delivery, and at the same time to meet the health standards of the medical industry, PEEK seals to meet these requirements.

Artificial Joint Seals

In artificial joints, PEEK seals can be used for sealing joint parts, providing good motion performance and stability.

The development trend and prospect of PEEK seals

With the continuous progress of science and technology and the increasing demand for high-performance seals in various fields, the development prospect of PEEK seals is very broad. In the future, PEEK seals will develop in the following directions:

High performance
