We expertly guide you through membrane keypad material selection you help achieve the best balance of cost and performance.
Substrate - Given its flexibility, high durability, long life cycle and chemical resistance properties, polyester is the most used and preferred substrate for graphic overlays, particularly for environments where harsh cleaning agents or chemicals are frequently used. Depending on the application requirements In2tec may recommend an alternative substrate material.
Ink – Usually the conductive inks are made from silver particles in a plastic extender. Carbon inks are also used but they have a conductance of about 500 times less than that of silver inks.
Adhesives – We have a couple of options for the adhesives we use, however, the most used and preferred is Isotropic Conductive Adhesive (ICA). This is because ICA conducts electricity in all directions.
