Membrane can be attached to aluminium panels so as to have a membrane panel when the additional cost is set off by the existence of the following factors:
α) Waterproofing of panels and instruments inside.
b) Placing underneath a rigid electronic circuit with mechanical membrane keys to create industrial keyboard type.
c) Coverage of display (7-segment or LCD) where the membrane is especially processed (transparent red co lour or shining it).
d) Protection of printing as it is at the back of the membrane.
e) Better aesthetics.
Membranes are distinguished according to the raw material they are produced, their thickness (thin-thick) and finally the special exterior surface preprocessing (hard mat, fine mat, glossy ).
Τhe membranes are scratch resistant and are of high thermal, chemical and mechanical strength.
