Printable Surfaces for Printed Electronics
Hi-Res Clear Printable Coating

White Coated
Black Polyimide XF-106
Polyimide is the preferred material for applications requiring a high degree of dimensional stability after exposure to extreme temperatures (up to 300°C). In addition, polyimide offers a high resistance to chemicals and is light weight and flexible making it an ideal substrate for printed electronics applications.
Polyonics PolyFLEX flexible substrates include clear and white printable coatings that produce hi-resolution images using conductive inks in Flexo and Screen printing processes. The proprietary polymer coatings have been evaluated by leading conductive ink suppliers as providing increased ink receptivity, superior ink adhesion and high resolution printing.
Antistatic Technology
Polyonics ESD-Safe polyimide and polyester (PET) films include durable, non-metallic static dissipative top coats that provide surface resistances of >105 and <109 Ohms. The materials have proven to help designers and manufacturers package and protect their most static sensitive devices from electrostatic charges arising from both human contact (HBM) and charged devices (CDM) and are valuable elements in the successful S20.20 ESD Control Plans of global electronics EMS’, ODMs, converters and OEMs.
