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)

Pack Content

  • 2 pcs PEI plate, 120×40 mm (4.72×1.57 in) each

Thickness Options

4 mm (0.157") 5 mm (0.197") 6 mm (0.236") 8 mm (0.315")

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

CUSTOM FABRICATION

Can't Find the Right Size or Specification?

Send your drawing or dimensions, material grade if known, quantity and intended use. We review feasibility and confirm the specification for each quoted project.

Project Requirements

Identify the critical dimensions, tolerances, surface finish and inspection requirements. Any required food-contact, ESD, flame-retardant or other compliance documents should be specified so availability can be checked. Material names alone do not establish these properties.

Custom Order Process

Submit the requirements for review. The quotation will identify the agreed specification, quantity, production lead time and inspection requirements. Shipping method, shipping charges and tax responsibilities are confirmed separately from production timing. Approve the final quotation and specification before ordering.

Send Your Drawing or Requirements

Use the enquiry form to send your project details and a file link, or email drawings to beeplastic@beeplastic.com. Include the product and specification. If the material grade or tolerance is uncertain, describe the intended use for review.
