Ultem 1000B, Ultem 5000B and Ultem EXSP0023 are the first members of a family of PEI films based on X Gen resin technology and characterised by their excellent temperature performance and electrical properties. The new Ultem films offer high performance across a broad range of demanding applications, bridging the gap between lower performing and more costly materials.
They are generally well suited for use in various electronics applications where superior performance, economy and durability are required.
The PEI films are targeted at several industries where GE Advanced Materials sees promising penetration and growth for the products, particularly the global electronics industry.
Flexible circuitry, for example, is an area where GE predicts strong growth during the next three to five years and where - because of the thermoplastic self-sealing properties of the new products - there is potential to eliminate the use of adhesives.
With other strong and accelerating drivers such as component miniaturisation, moulding in increasingly thinner walls, higher heat requirements, and OEM demand for higher quality film technologies, applications for the new films in mobile phones, lap-top computers, pagers, PDAs and other electronic devices are expected to increase, as well.
"The global fit for these new products is very broad", said Nick Abbatiello, GE Advanced Materials industry manager, Global Marketing.

French distribution for high-performance films
GE Plastics Specialty Film and Sheet has appointed Saint Chamond-based Micel Industrie as a new distributor of its high-performance Ultem films for electrical and electronic applications
"They cut across a wide swath of applications where exceptional properties - especially superior high-heat and electrical performance - are key.
We're looking at everything from the electronics and electrical industries to healthcare, automotive, and others where a balanced cost/performance alternative to polyimide (PI) film is needed".
According to Abbatiello, other potential applications for the new PEI films include barcode labels, flexible heaters, stiffeners, insulating tapes, motor insulation, speaker cones, wire wrapping and a wide array of thermoformable products.
"We can't overemphasise how pleased we are to be able to offer these new films to our customers", said Ed Martin, GE Advanced Materials Market Director for Consumer Electronics, Portables and Displays.
"They represent a value-added technology that the marketplace has been demanding for quite some time".
Ultem EXSP0023 film offers the highest heat performance of the three new grades.
With a glass-transition temperature (Tg) of 245C, it also has a dielectric strength of 185kV/mm and good tear resistance.
It is heat sealable and offers good overall adhesion to most metals.
This product also provides excellent chemical resistance and a low relative permittivity of 2.9 when tested at 10GHz.
Ultem 5000B film is the second of the three new materials in high-heat performance, with a Tg of 225C.
In addition, it offers exceptional tear strength and a dielectric strength of 208kV/mm.
Its relative permittivity is 3.3, with a dissipation factor of 0.006.
This new film is also heat sealable, provides good adhesion to most metals and is highly resistant to chemicals.
Also offering good metal adhesion and chemical resistance, Ultem 1000B film provides good high-heat capabilities, with a Tg of 217C.
This product also features good dielectric properties and excellent tear strength, with a dissipation factor of 0.005.
Ultem 1000B, 5000B, and EXSP0023 films are commercially available from GE Advanced Materials in thicknesses from 50 to 700um and in widths up to 48in.
