Applications of PEEK
Polyetheretherketone (PEEK) material, with its various performance advantages, has become one of the indispensable key materials in modern high-tech fields. Based on our company's years of production and application experience, we will deeply explore the specific applications of PEEK materials in core industries such as healthcare, new energy vehicles, petrochemical and natural gas, and electronic semiconductors.
Healthcare
In the medical field, PEEK has become a preferred material for human implants due to its high biocompatibility, sterilization resistance, and X-ray translucency. It is widely used in spinal fusion cages (its elastic modulus of about 3.8 GPa is close to that of human bone, reducing stress shielding and promoting bone healing), trauma fixation plates, and dental implants. The material's transparency to X-rays allows for clear post-operative observation. Furthermore, it can withstand repeated high-temperature sterilization, ensuring patient safety and a smooth recovery.
New Energy Vehicles
The new energy vehicle industry has high demands for lightweight and high-performance materials. PEEK has become a primary alternative to metal, thanks to its high strength, wear resistance, heat resistance, and chemical inertness. It is often used to manufacture engine piston rings, transmission gears, fuel system seals, and electrical connectors. PEEK not only increases the service life of components but also improves fuel efficiency.
Petrochemical and Natural Gas
PEEK material excels in petrochemical and natural gas applications due to its high resistance to chemical corrosion, high temperatures and pressures, and its self-lubricating properties. It is widely used to manufacture seals, valve seats, bearings, and pump components for downhole oil equipment. PEEK can effectively withstand hydrocarbons, corrosive fluids, and high-pressure environments, which reduces maintenance costs and extends the lifespan of equipment.
Electronics and Semiconductors
In the electronics and semiconductor industries, PEEK's high-temperature resistance, low moisture absorption, high purity, and low particle generation are crucial for its applications. It is used to manufacture wafer carriers and test sockets, among other components. The use of PEEK effectively improves wafer yield and production efficiency, meeting the stringent material requirements of the semiconductor industry.

PEEK Films
Advanced Film Solutions for Modern Technology
Applications in Electric Vehicles
PEEK film is mainly used in electric vehicles for battery separators, motor insulation layers, cable sheaths, etc. Due to PEEK material's excellent electrical insulation and high temperature resistance, it can ensure safety during operation and prevent loss of control due to excessive temperature.
As insulation film in motor windings, PEEK can provide reliable electrical isolation. PEEK film is used as insulation layer for high-voltage cables to prevent high-voltage breakdown.

High-Performance Bundling for Extreme Environments
Water-Lubricated Bearings
Water-lubricated bearings are critical components of pumps. They bear the axial force of the pump's rotating parts and stabilize the rotation of the impeller. If the bearing wears excessively or is severely damaged, it can lead to increased axial play in the unit, severe vibration, and even impeller rubbing.
Most pump failures during operation are due to water-lubricated bearing failures. Therefore, these bearings are a key controlling factor for a pump's reliability, service life, and planned overhaul cycle.
Plunger Pumps
Our company's modified PEEK materials offer a range of advantages, including high mechanical strength, high-temperature resistance, self-lubricating properties, corrosion resistance, and excellent dimensional stability.
When our modified PEEK is paired with stainless steel as a plunger and slipper pad, the pump operates with high efficiency and stability while minimizing wear.
