Autostat is a range of heat-stabilized polyesters, originally designed for printed electronics. They are available in white, clear, and hazy formats. Heat stabilization means that the sheets have low residual shrinkage, <0.2% shrinkage after 30 minutes @ 150 ̊C. Heat stability is essential when tight registration tolerances need to be maintained during multiple printing operations. This is critical for printed electronics where the first layer of silver ink is dried at 120 ̊C and subsequent ink layers need to align exactly. The initial high-temperature drying stage will not affect the dimension or lay flat of Autostat.

These are ideal substrates for higher-temperature printing processes.

Autostat films are typically used for flexible circuitry, membrane switch circuitry, flexible flat cables, sensors, and RFID antennae. White, thick gauges are also used for medical sensors.
