Polycarbonate and polyester are used in all those sectors employing machinery equipped with control panels (household appliances, electrical equipment, agricultural machinery and health care). They are also used to make keyboards with padded keys of various sizes and coupled with double-sided stickers, which are often indicated in the technical specification of the customer.
Always from these two materials, transparent inserts can be obtained in correspondence of leds. Polycarbonate is resistant to scratches and pressure of the padded keys for over 10,000 presses and is a conformable material even for domes with high thickness keys. For this type of processing, Seri-Art adapts the thickness of the film according to every specific need: between 200 and 750 microns with matt or polished finish.
