Electronics and Electrical Appliance Field

• Connectors: A large number of connectors are required inside electronic devices to achieve circuit connections. PPS has excellent dimensional stability, electrical insulation, and soldering resistance, which can ensure that connectors maintain precise dimensions and good electrical performance during long - term use and soldering processes. It is widely used in the manufacture of connectors for various electronic devices such as computers, mobile phones, and smart home devices.
• Sockets: As frequently used electrical components in daily life, sockets need to have good flame retardancy and mechanical properties. PPS itself has excellent flame - retardant characteristics and can meet high - level flame - retardant standards. It also has high mechanical strength, which can ensure the structural stability of sockets during plugging and unplugging processes and guarantee electrical safety.
• Coil formers: In electronic components such as transformers and relays, coil formers play a role in supporting and insulating. The high insulation and dimensional accuracy of PPS can effectively prevent coil short - circuits and maintain the stability and reliability of components, ensuring the normal operation of electronic components.
• Circuit boards: As electronic products continue to develop towards miniaturization and high - performance, the requirements for circuit board materials are getting higher. The low dielectric constant and loss factor of PPS, as well as its good heat resistance and chemical stability, make it an ideal material for manufacturing high - frequency and high - speed circuit boards.

Automotive Industry Field

• Engine peripheral components: When the engine is working, it generates high temperatures and various corrosive substances, so the material performance requirements for peripheral components are extremely high. The high temperature resistance of PPS allows it to withstand the high - temperature environment of the engine, and its corrosion resistance enables it to resist the erosion of engine oil, coolant, etc. Components such as throttle bodies, intake manifolds, and spark plug seats are mostly made of PPS materials.
• Electronic control system components: The electronic control systems of modern cars are becoming increasingly complex, with strict requirements for the reliability and accuracy of components. The dimensional stability and good electrical performance of PPS can ensure that electronic control system components such as sensor housings and connectors accurately transmit signals in different working environments, ensuring the stable operation of the automotive electronic system.
• Automotive interior parts: PPS materials have low volatility and good flame retardancy, which can be used to manufacture automotive interior parts such as dashboards and seat frames. They can not only meet the aesthetic and comfort requirements of interior parts but also improve the safety of the vehicle.

Aerospace Field

• Aircraft internal structural parts: In the aerospace field, there are extremely high requirements for material lightweight and high strength. PPS has a high strength - to - weight ratio, which can reduce the weight of the aircraft structure while ensuring its strength and stability. It can be used to manufacture internal supports, partitions, and other structural parts of aircraft.
• Electronic device housings: Various electronic devices on aircraft need to work in harsh environments. The high temperature resistance, corrosion resistance, and electrical insulation of PPS can provide reliable protection for electronic devices, ensuring their normal operation under extreme conditions such as high altitude, high temperature, and high pressure.
• Engine components: The working conditions of aircraft engines are extremely harsh. The high temperature and chemical corrosion resistance of PPS make it suitable for manufacturing some non - critical but high - requirement engine components, such as engine heat shields and oil pipe connectors.

Mechanical Industry Field

• Gears and bearings: PPS has good wear resistance and self - lubrication properties, which can reduce friction and wear during the operation of gears and bearings, lower noise, and improve mechanical efficiency and service life. It can be used to manufacture transmission gears and bearings in various mechanical equipment.
• Pump bodies and valves: In the fluid transportation systems of industries such as chemical engineering and petroleum, pump bodies and valves need to withstand the erosion of various corrosive media. The excellent chemical corrosion resistance of PPS makes it an ideal material for manufacturing pump bodies, valves, and other components, ensuring the long - term stable operation of equipment.

Environmental Protection and Medical Fields

• Environmental protection field: In environmental protection equipment such as waste incineration and sewage treatment, filter materials made of PPS fibers have good high - temperature resistance, corrosion resistance, and filtering performance, which can effectively filter harmful substances in waste gas and sewage and improve the treatment efficiency of environmental protection equipment.
• Medical field: PPS has good biocompatibility and disinfection resistance, and can be used to manufacture some medical equipment and instruments, such as surgical instrument handles and dental equipment components. At the same time, PPS materials can also be used to manufacture medical packaging materials to protect drugs and medical devices from contamination.
