Durable Black ESD PEI Sheet - ideal for extreme structural applications in semiconductor and electronics markets
Product Introduction
ESD PEI (Electrostatic Discharge Polyetherimide) is a high-performance thermoplastic material modified by adding conductive fillers (such as carbon black, carbon fiber or metal oxide), combining the high temperature resistance, high mechanical strength and antistatic properties of PEI (polyetherimide).
Durable Black ESD PEI Sheet
Why choose ESD PEI?
Adaptation to electrostatic sensitive environments: Semiconductor packaging and electronic assembly lines need to remove static electricity to prevent chip breakdown.
Metal replacement and lightweighting: Replace aluminum alloy in automotive sensors and aerospace components to reduce weight and maintenance costs.
Extreme temperature stability: Suitable for high-temperature welding scenarios or engine peripheral components.
Processing efficiency: Supports injection molding, molding and CNC processing, and adapts to the needs of precision structural parts.
Scope of application and specific applications
Electronic manufacturing: semiconductor packaging molds, anti-static workbenches, chip carriers, high-frequency connectors.
Automotive industry: sensor housings, wiring harness sheaths, ignition system brackets (resistant to 130°C+).
Medical equipment: surgical instrument handles, sterilization-resistant parts (certified by ISO 10993).
Aerospace: lightweight structural parts, fuel system connectors, high-temperature resistant gaskets.
Precautions
Processing temperature: Avoid exceeding 380°C to prevent PEI degradation or conductive filler failure.
Conductive path design: The conductive area needs to be controlled by surface plating or coating to avoid accidental conduction.
Recycling: It cannot be melted and regenerated, and can only be crushed for filler or industrial waste treatment.
Safety protection: Carbon fiber dust is generated during processing (long-term inhalation is harmful to the lungs), and dust masks must be worn.
Summary
ESD PEI achieves a balance between antistatic performance and high-performance engineering plastics by combining conductive fillers with PEI substrates. Its core advantages are high temperature resistance, lightweight and antistatic functions, and it is especially suitable for precision parts in the semiconductor, automotive and medical fields. Compared with metal materials, it has lower costs and can be formed in complex shapes; compared with ordinary PEI, its functions are more suitable for electrostatic sensitive environments. Choosing ESD PEI can improve equipment reliability while meeting lightweight and cost control requirements.
