Film answers cost/performance dilemma

Ultem 5000B film features high temperature and flame resistance, low moisture absorption and excellent dielectric properties

For electrical and electronics manufacturers that previously faced the dilemma of choosing between the high cost of specifying polyimide (PI) to achieve desired performance, or downgrading an application by using lower-performing polyethylene napthalate (PEN) or polyester (PET), there is now a solution.

Ultem 5000B film from GE Plastics offers high performance coupled with cost-effectiveness.

Based on GE's Ultem polyetherimide (PEI) resin, this material's high temperature and flame resistance, low moisture absorption and excellent dielectric properties make it an excellent candidate for electrical and electronics applications such as insulating tapes and laminates, diaphragms and voice coils for loudspeakers, high temperature barcode labels and flat flexible heaters.

Ultem 5000B film is available in black and amber and in gauges from 25 to 750mm.

"This new GE film is what the market has been waiting for", said Max Cattani, GE Industry Manager for High-Performance E/E films, Europe.

"Ultem 5000B film gives E/E manufacturers a combination of high performance and cost-effectiveness - reducing the need to overspecify materials or compromise on properties".

"And this new grade is highly versatile in terms of processing and range of potential applications".

The new GE film offers a wide choice of processing, including thermoforming, drilling, die-cutting, cold-forming, laminating, metal sputtering and ultrasonic welding.

It is heat-sealable to itself and other materials.

In contrast, PI standard grades cannot be thermoformed and Aramid paper releases dust during some processes.
