Abstract:
Film laminates containing a layer of a lower melting polyaryletherketone and a layer of a higher melting polyaryletherketone adhered to each other are resistant to heat, wear, moisture, weathering and chemicals and are useful for producing articles such as laminated electronic circuits, flexible heaters, insulated wire and cable, radio frequency identification tags and labeled articles.
