Simply put, Flexible Printed Heaters are warming elements that are screen printed on flexible materials. Through the precise control of design elements and deposition of functional inks, flexible printed heaters can be made to specific operating parameters. To create these unique heater applications; a full range of conductive, resistive, and positive temperature coefficient inks are used in combination with flexible substrates such as polyester (PET), polyimide (PI), polycarbonate (PC), Kapton ® RS Conductive Film, and thermoplastic polyurethanes (TPU).
