ESD PEI Sheet: High-Temp Static-Safe Engineering Plastic for Demanding Industries

ESD PEI sheet is a high-performance, static-dissipative thermoplastic built for environments that need both extreme heat resistance and reliable electrostatic control. Unlike standard Ultem PEI Sheet that soften or degrade under stress, this material combines stable anti-static performance with the mechanical and thermal strength of PEI, making it ideal for high-tech, high-heat, and precision-critical applications.

Key Benefits

• Stable ESD Performance

   

  Provides consistent static dissipation without relying on surface coatings. Performance remains reliable across changing temperatures and humidity, protecting semiconductors, PCBs, and delicate electronic components during processing and assembly.
   

• Excellent High-Temperature Resistance

   

  Maintains rigidity and shape even under continuous high heat, making it suitable for SMT processes, wave soldering, and high-temperature manufacturing environments where common plastics would warp or fail.
   

• Strong Mechanical Properties

   

  Offers high tensile strength, impact resistance, and dimensional stability. It resists creep, holds tight tolerances, and performs reliably under mechanical stress.
   

• Good Chemical & Flame Resistance

   

  Inherits PEI’s natural resistance to many chemicals, oils, and solvents. It also supports flame-retardant properties without additives, supporting safer production setups.
   

• Easy to Machine & Fabricate

   

  Can be milled, drilled, turned, and precision-machined into custom components without losing ESD performance. Works well for structural parts, fixtures, and housings.
   

Typical Applications

• Semiconductor manufacturing fixtures and test components

• SMT assembly trays, carriers, and high-temperature pallets

• Electronic test equipment and cleanroom parts

• Aerospace and automotive electronic components

• High-temperature static-sensitive automation tooling
