Product details

HONYPLAS®Polyimide(PI) Polyimide is a non melting high temperature polymer. Strength, dimensional stability, and creep resistance remain high even at temperatures above 260°C. Low wear rates combined with the ability to work under unlubricated conditions and high pV-rates makes it the ideal material for challenging friction and wear applications, extending lifetime and reducing maintenance costs. Its high purity and low outgassing are needed for applications in the vacuum, space and semiconductor industry.

Special properties of Polyimide PI
Long-term thermal stability 300 °C (short-term up to 400 °C)
Good cryogenic properties down to -270 °C
High strength, modulus and stiffness also at high temperatures over 260 °C
Excellent wear resistance under high surface pressure and high sliding speeds
Excellent thermal and electrical insulation
Minimal thermal conductivity
High purity, low outgassing in vacuum conditions in accordance
Good machinability
Good chemical resistance to acids, fats and solvents
Highest flame retardant grade UL-94 V-0
Irradiation resistance
Aging resistance
Polyimide PI is ideal for electrical and thermal insulating applications. More ductile than ceramics, and lighter weight than metals, and lighter weight than metals, Polyimide PI sheet plate is an excellent choice for structural parts in aerospace and other applications where metal replacement is desirable.

In Semiconductor Wafer Processing applications, Polyimide PI sheet plate can be machined as Polyimide PI wafer handling tools (wafer tips).

For IC Test Sockets & Probe Test Heads, Polyimide PI sheet plate is also an excellent replacement for Vespel® SP-1. Polyimide PI sheet plate feature Continuous Operational Temperatures up to 550ºF (260ºC) and Intermitting Operation up to 900ºF

Polyimide PI sheet plate is Compression Molded.

Description Grades of SNC Polyimide PI
HONYPLAS®PI Unfilled – Natural (Unfilled) PI Highest elongation and purity. Equivalent of Vespel SP-1

HONYPLAS®PI-G15- self-lubricating grade with 15% graphite. Equivalent of Vespel SP-21

HONYPLAS®PI-Bearing bearing and wear grade, superior thermal stability. Equivalent of Vespel SCP-5050

Typical Applications of Polyimide PI
Semiconductor Industry: semiconductor manufacturing process equipment with high purity, high resistance. Such as wafer clamping rings, wafer carries, wafer guides, wafer tips, die-pickup collets, vacuum pads, bearings, centering pins, alignment pins, insulators, screws & fasteners, Semicon Insulator Bushing，Plasma Torch Tips，IC Test Sockets & Nests
Automotive industry: thrust washer or piston rings in transmission and pumps replacing traditional metals
Aero space industry: Jet engine parts such as pads, bumpers, seals and bearings
Industrial machinery: nozzle tip insulators for hot runner nozzles used for injection molding of thermoplastic products such as PET preforms, PET caps
Polyimide PI in the glass industry. The use of polyimide PI can enhance productivity in the manufacture of glass bottles for container glass, the pharmaceutical and cosmetics industry. Polyimide PI excellent temperature resistance and low thermal conductivity lend these high-performance plastics key benefits, particularly for hot-glass handling, compared to components made of graphite. They also help extend the service life of components and improve the rate of the production. In addition, Polyimide PI materials are economical to process, making them an ever more popular alternative for the production of take-out inserts and bottle grippers.

Machining Polyimide PI Vespel equivalent
Polyimide PI Vespel offers ease of machining and tight tolerances due to its inherent mechanical strength, stiffness and dimensional stability. Machining Polyimide PI Vespel isn’t too different from machining metals as a result of this; pretend you’re machining brass. Unlike metal, though, Polyimide PI Vespel (like all thermoplastics) will deform if you hold it too tightly.

We generally recommend Tungsten Carbide Alloy Tooling, although we recommend diamond tooling for large volume runs or work requiring close tolerances. Be wary of overheating Polyimide PI Vespel when you machine it. It shouldn’t become so hot that you can’t grasp it with your bare hands.
