The application of PEEK material in the field of electronic and electrical products
PEEK (Polyetheretherketone) is a key high-end material in the electronics and electrical field due to its outstanding comprehensive properties, primarily used in scenarios demanding high performance, reliability, and precision. Its applications in this sector are mainly reflected in the following aspects:
1. Semiconductor Manufacturing and Packaging
· Wafer Manufacturing and Processing: Used for critical components such as wafer carriers, wafer chucks, and CMP (Chemical Mechanical Polishing) retaining rings. PEEK offers high purity, low outgassing, high-temperature resistance (withstanding process temperatures ≥260°C), plasma corrosion resistance, and excellent dimensional stability. This helps reduce wafer contamination, cooling time, and electrostatic discharge risk, thereby improving yield and production efficiency.
· Packaging and Testing: Used for connectors, insulating films, printed circuit boards (PCBs), and high-temperature connectors. Its excellent electrical insulation, high-temperature resistance, and dimensional stability ensure reliability in high-density, high-frequency signal transmission.
2. Consumer Electronics and Communication Equipment
· High-Frequency Connections and Antennas: Leveraging its low dielectric constant, low loss factor, and stable high-frequency performance, PEEK is an ideal material for manufacturing 5G base station antenna brackets and built-in mobile phone antennas (e.g., in Apple phones), replacing traditional materials like LCP, PI, and metals to provide more stable signal transmission.
· Micro Speakers and Receivers: Used for acoustic components like speaker diaphragms and mobile phone microphone spacers. Its high rigidity, lightweight nature, and excellent acoustic properties enhance sound quality and durability.
· Precision Structural Parts: Used to manufacture tooling fixtures, bearings, gears, and screws. Its wear resistance, self-lubrication, fatigue resistance, and dimensional stability ensure precision assembly and long-term operational accuracy.
3. Other Electronic and Electrical Components
· Cables and Insulation: PEEK-coated cables feature high-temperature resistance, flame retardancy, and radiation resistance, making them suitable for applications like new energy vehicle high-voltage motor winding wires (e.g., 800V systems), aviation ultra-high-temperature wires, and robotic joint cables.
· Capacitors and Connectors: Used for aluminum capacitor housings to enable lead-free soldering and for manufacturing high-performance electrical connectors that meet demanding requirements in high-temperature, high-humidity environments.
Core Driving Factors: This sector accounts for a high consumption share (27% of the Chinese market in 2024). Growth is primarily driven by: 1) 5G infrastructure deployment boosting demand for high-frequency components; 2) Accelerated semiconductor supply chain localization (e.g., increased procurement of domestic PEEK carriers by SMIC); 3) Consumer electronics innovation (e.g., applications of biodegradable PEEK).
