Membrane Switch Material Selection

The two most widely used graphic materials are polycarbonate and polyester. polycarbonate comes in thicknesses of 0.127 – 0.762mm thick while polyester comes in thicknesses of 0.127 – 0.254mm.

Polyester has greater tensile strength than does polycarbonate, which often allows it to withstand millions of actuation before fracturing. Also, polyester has a greater resistance to a broad range of chemicals.

Polycarbonate is slightly easier to both print and emboss.
