PRODUCT DETAILS
PI (Polyimide) Rod – High-Temperature Engineering Plastic
Brown polyimide (PI) round rod for parts that must keep their strength, shape and low wear at temperatures where most plastics soften. Polyimide does not melt, has very low outgassing and keeps good dimensional stability, which is why it is used for high-temperature insulators, seals, bushings and precision parts in aerospace, electronics and semiconductor equipment.
Material note: this is generic PI stock. It is not DuPont™ Vespel®, and BeePlastic is not affiliated with DuPont. If your drawing specifies a branded grade (for example Vespel® SP-1), please contact us before ordering so we can confirm what we can supply and with which certificates.
Available sizes
- Diameters: 1.8, 3, 4, 5, 6, 8, 10, 12, 13, 15, 16, 18, 20, 22, 25, 30, 35, 40, 45, 50, 55 and 60 mm
- Length: 307 mm
- PI sheet, other sizes and finished machined parts: request a quote
Typical properties (unfilled PI)
| Density | approx. 1.4 g/cm³ |
| Melting point | none – does not melt |
| Long-term service temperature (air) | approx. 260–290 °C, grade dependent |
| Outgassing | very low |
| Electrical insulation | very good |
Typical values for unfilled polyimide, for reference only and not a specification. Ask us for the supplier datasheet before using the material in a critical application.
Key advantages
- Keeps strength and stiffness at very high temperature
- Low wear and friction in dry running, good creep resistance
- Resists most oils, fuels and organic solvents
- Low outgassing, suitable for vacuum and clean environments
Note: polyimide can be attacked by strong bases and by prolonged hot water or steam. Check chemical compatibility before use.
Typical applications
High-temperature insulators and spacers, valve seats and seals, thrust washers and bushings, wafer-handling and test-socket parts, and components for vacuum, aerospace and electronics equipment.
Machining tips
- Use sharp carbide tools and light finishing passes; PI is hard and can chip on exit.
- Dry machining or air cooling is preferred.
- Dry the material before high-precision machining if it has been stored in a humid environment.
Ordering, cutting and lead time
For custom sizes, sheet or machined PI parts, send your drawing or dimensions to beeplastic@beeplastic.com. We reply within 1 business day, and the lead time is confirmed with your quote.
