PEI films - resistant to high temperatures
Ultem™
Ultem™ 1000 is a flame-retardant PEI film which offers an excellent combination of a performance at high temperatures with low moisture absorption and dielectric strength. It has been used in high voltage internal insulation, high-temperature PSA tapes, motor slot liners and wedges, transformer wraps, layer and phase insulation, and speaker cones. ULTEM™ 1000B film is a thermoformable material and can be heatsealed to a wide variety of metals and thermoplastics. Ultem™ 1000 is available in different thicknesses on demand and is offered in rolls and sheets.

FAQ
What are PEI films?
PEI films are high-performance films made from the thermoplastic polyetherimide (PEI), which are characterised by high temperature resistance, flame retardancy, low moisture absorption and good electrical insulation. They are used in electronics, electrical engineering and for technical applications.
What material are PEI films made from?
PEI films are made of polyetherimide (PEI), an amorphous high-performance polymer. Brands such as Ultem™ offer particularly temperature-stable variants with excellent chemical resistance and thermal properties.
What are the characteristics of PEI films?
PEI films combine high heat resistance, flame retardancy (UL 94 VTM-0), low moisture absorption, good dielectric resistance, chemical resistance and thermoformability. They can be laminated, heat sealed, welded and metallised.
What are the typical applications of PEI films?
PEI films are used for internal high-voltage insulation, transformer windings, motor insulation, high heat-resistant adhesive tapes, printed circuit board base material, loudspeaker membranes and layer or phase insulation.
In what thicknesses and formats are PEI films available?
PEI films are available in rolls or cut-to-size sheets, typically in thicknesses from 0.125 mm. Widths and lengths can be requested individually, suitable for industrial processing and prototypes.
What is the temperature resistance of PEI films?
PEI films are extremely heat-resistant and can be processed at temperatures of up to 200 °C without losing their shape or properties, making them ideal for high-temperature applications.
How can PEI films be processed?
PEI films are thermoformable, weldable and heat sealable. They can be punched, cut, deep-drawn, laminated and metallised without special accessories and retain their mechanical and electrical properties.
Can PEI films be cleaned?
PEI films with a smooth surface can be cleaned, but a compatibility test should be carried out beforehand on an inconspicuous area to avoid surface changes caused by cleaning agents.
