Panasonic Industrial Devices Sales Company of America, Division of Panasonic Corporation of North America, through its Electronic Materials Division, is proud to introduce BEYOLEX™, a new thermoset stretchable film 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.
This new product 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 the 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™ substrate attractive 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.
Product Features:
Good Elongation: More than 200%
Soft and Conformable: Modulus of less than 2.5 MPa
Ultra-Low Hysteresis: Less than 0.1% permanent deformation after 100% stretching
High-Temperature Resistance: Greater than 300°C
Transparent: More than 90% Transmission Over Visible Spectrum
Good Electrical Properties: Breakdown Voltage 98 kV/mm
This novel non-silicone polymer resin system exhibits amazing properties when made into a film,” said Takatoshi Abe, Research Manager, Panasonic Electronic Materials Division and Co-inventor of BEYOLEX™ technology. “We think this technology - which our team developed, patented, and commercialized - can be the foundation for many new innovative products that will improve people’s lives.
No Other Printed Electronic Substrate like BEYOLEX™
As electronic devices become more ubiquitous, their form-factors have evolved to meet their end-use requirements. Traditional printed electronic substrates like polyester and polyimide films are not pliable, stretchable, or soft. Silicone-based films can be incompatible with standard electronic materials and processes. Thermoplastic polyurethanes (TPU) are commonly used as a substrate for pliable printed electronics, but these films have low-temperature resistance and can be prone to permanent deformation after being strained.
“We view electronic materials based on this polymer technology as enabling an entire new class of soft and pliable electronic devices,” said Andy Behr, Technology Manager, Panasonic Electronic Materials.
Availability
BEYOLEX™ film is initially available as Panasonic product number MUAS13111AA: A4 size (210mm x 300mm) sheets, 5 sheets per package. Custom configurations, roll, or sheet sizes may be available depending on minimum order quantities. Packages of BEYOLEX™ MUAS13111AA will be available for purchase from selected distribution partners in North America.
