Panasonic BEYOLEX™ Film is a Novel Polymer Substrate Designed for Flexible, Stretchable, Conformable, and Pliable Printed Electronics Applications

Panasonic is proud to introduce BEYOLEX™, a new thermoset stretchable film polymer substrate for printed electronics. This novel material is based on a proprietary non-silicone thermoset polymer chemistry developed by Panasonic researchers at the Electronic Materials laboratory in Kadoma, Osaka, Japan. 

BEYOLEX™ features softness, conformability, high-temperature resistance, and ultra-low permanent deformation after stretching. The stretchable film is 100 microns in thickness, delivered on a high-temperature Polyethylene naphthalate (PEN) carrier for mechanical stability during processing and a thin Polyethylene terephthalate (PET or polyester) coversheet for protection. The high surface energy of Panasonic's BEYOLEX™ substrate makes it compatible with a wide variety of functional inks and pastes, including screen-printed stretchable silver composite pastes; sintered metal pastes; and liquid metals like eutectic Indium Gallium alloys. These properties make BEYOLEX™ an attractive substrate for many end-use applications including, but not limited to, health/wellness, automotive, sensors, haptics, Internet of Things (IoT), gaming, augmented reality (AR), soft robotics, and aerospace.
