Specifications
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
