Performance advantage and application of PEEK in automotive field
In the field of automotive manufacturing, the choice of materials is crucial to the performance, durability and safety of the vehicle. With the rapid development of the automobile industry, the requirements for material properties are also increasing. PEEK as a kind of high-performance special engineering plastics, in the "plastic instead of steel", "lightweight" under the background, with its excellent performance in the high-end field gradually replace the use of metal materials, making it become one of the indispensable high-performance materials in the modern automotive industry, in the automotive field more and more widely used.
Material characteristics 7 advantages
1: Excellent high temperature resistance
PEEK material has excellent high temperature resistance, its long-term operating temperature range can be from -100℃ to +250℃, and even in some specific conditions can withstand high temperatures of up to 260℃. This enables PEEK material to maintain stable performance in high temperature environments such as engines and exhaust systems, effectively extending the service life of auto parts.
2: Excellent mechanical properties
PEEK material has high strength, high stiffness, high wear resistance and good fatigue resistance. These excellent mechanical properties give them a significant advantage in the manufacture of key components such as seals, bearings and gears inside engines. In addition, PEEK material also has good self-lubrication, which can reduce friction and wear between parts, and further improve the performance and reliability of the vehicle.
3: Excellent chemical stability
PEEK material has excellent chemical stability and can resist the erosion of a variety of chemical substances. In the automotive fuel system, PEEK material can be used to manufacture fuel pumps, fuel injectors and fuel lines and other components, its good chemical stability makes these components can resist the corrosion of fuel, thereby extending the service life.
4: Low moisture absorption and dimensional stability
PEEK material has very low hygroscopicity and excellent dimensional stability. Even in high temperature, high humidity environment, PEEK material can maintain a stable size and performance, which is essential to ensure the accuracy and reliability of automotive parts.
5: Easy to process and shape
PEEK material has good processing properties and can be processed by extrusion and other molding processes. This makes PEEK material highly flexible and customizable in the automotive parts manufacturing process, able to meet the manufacturing needs of different parts.
6: Lightweight design
The density of PEEK material is relatively low, only about 1/7 of metal. The use of PEEK materials to replace traditional metal materials for the manufacturing of automotive parts can significantly reduce the overall weight of the vehicle, thus achieving lightweight design. The lightweight design helps to improve the fuel economy and reduce emissions of the vehicle, which is in line with the development trend of the modern automotive industry.
7: Environmentally friendly and recyclable
PEEK material has good environmental performance and can reduce environmental pollution through recycling. In the automobile manufacturing process, the use of PEEK materials to replace traditional metal materials not only helps to reduce the manufacturing cost of automobiles, but also helps to achieve environmental protection and sustainable development goals.
