We exclusively use MacDermid Autotype heat stabilised Polyester Films (PET) for all our Membrane Keypads and Capacitive sensors.
Our preference is to also use MacDermid Autotype Polyester film for our Graphic Overlays, we offer the full range of textures.
Independent testing has shown that Polyester will give you by far the best longevity over alternative substrates such as polycarbonate or Lexan films. Particularly when the overlay is embossed or is intended for external use.
Reid Industrial has access to a wide range of suppliers and substrates. If you have a project that requires a particular substrate, please let us know and we will do our best to track it down for you.
