Key Benefits of PEI Sheet / Plate (Polyetherimide Board)

🔥 High Heat Resistance
Typical glass transition around ~217 °C; suitable for hot-work fixtures and thermally demanding assemblies.
🛠️ Clean Machinability
Cut, drill, chamfer and CNC mill with sharp carbide tools to achieve accurate, burr-free edges.
📏 Dimensional Stability
Low creep and consistent flatness help maintain tolerances in precision plastic components.
⚡ Dielectric Reliability
Polyetherimide boards are widely used for electrical insulation plates, spacers and covers.

Available Sizes (Metric & Inch)

Specifications

Material: PEI (Polyetherimide), unfilled
Surface: As-sawn; ready for sanding/polishing
Color: Amber / translucent (batch variance is normal)
Nominal cut tolerance: ±0.5 mm (tighter machining on request)
Units: Dimensions listed in mm and inch
Customization: Tight tolerances, countersinks and edge rounding available

Typical Properties (Guide Values)

  • Glass transition, Tg ~217 °C
  • High stiffness with good wear performance
  • Good chemical resistance; low moisture uptake
  • Excellent electrical insulation characteristics

* Values are typical guide data only. For specification-critical applications, please contact us for application-specific recommendations.

Processing & Finishing Tips

  • Use sharp carbide (or diamond-coated) tools; step feeds help control heat.
  • For drilling, use peck cycles or air assist to avoid chip welding.
  • Sanding suggestion: P240 → P400 → P600/800; optionally polish for higher gloss.
  • Degrease surfaces before bonding; select adhesives rated for engineering plastics.

Common Applications of PEI Sheet / Plate

  • Electrical insulation boards & covers, insulating spacers and brackets
  • High-temperature fixtures, tooling plates and support pads
  • Precision plastic components requiring tight dimensional stability
  • Laboratory & workshop parts that need heat-resistant, machinable plastic
