PEEK (Polyetheretherketone) material is widely used in the automotive manufacturing field, primarily leveraging its comprehensive advantages such as lightweight, high-temperature resistance, wear resistance, corrosion resistance, self-lubrication, and excellent mechanical properties. It serves as a replacement for metals and traditional plastics to achieve weight reduction, enhance reliability, and improve performance. Specific applications can be divided into two main directions: traditional internal combustion engine vehicles and new energy vehicles.
I. Applications in Traditional Internal Combustion Engine Vehicles Primarily used for manufacturing critical components with demanding performance requirements:
1. Engine System: Engine inner covers, bearings, gaskets, seals, cylinder head gaskets, turbocharger compressor blades, vacuum pump blades, etc., utilizing its high-temperature and wear resistance.
2. Transmission and Braking Systems: Clutch gear rings, ABS brake valves, sealing rings, brake pads, etc., utilizing its wear resistance and self-lubricating properties.
3. Other Systems: Steering system components, bushings, electric seat gears, and various standard parts.
II. Core Applications in New Energy Vehicles (Key Growth Driver) New energy vehicles are the core driver of PEEK demand growth, with main applications including:
1. Power Battery Systems: Used as insulation material for battery packs, which can increase the volumetric energy density of modules (e.g., BYD's Blade Battery achieved an 18% improvement after adopting PEEK) and enhance safety.
2. High-Voltage Fast-Charging Systems: The enameled wire for 800V high-voltage motors is a clear future growth point. Due to its bendability, hydrolysis resistance, and high insulation, PEEK is an ideal insulation material for 800V high-voltage environments, potentially replacing traditional polyimide (PI).
3. Thermal Management Systems: Used for motor sealing gaskets, thermal management system seals, tire pressure monitoring sensors, and other high-temperature sealing components.
4. Electric Drive Systems: Used in bearings, gears, and other transmission components to achieve lightweighting and reduce noise.
Market Outlook: According to report data, the automotive sector consumed approximately 25% (about 1250 tons) of China's total PEEK consumption in 2024. It is projected that by 2027, the demand for PEEK from 800V motor enameled wire alone could reach 2630 tons, with an estimated market size of about 886 million RMB.
