What are the types of membrane switch materials?

From:admin Date: 2017-07-04
PVC PVC \ 60 ℃ \ 0.175 ~ 0.5 / smooth \ room temperature on the acid, alkali and salt stability. Good wear resistance, fire self-extinguishing, muffler shock, electrical insulation is good. Thermal stability is poor. Low standard plate, panel.
Polycarbonate PC \ -60 ~ 120 ℃ \ 0.175 ~ 1.0 \ high light transmittance, low water absorption, good dimensional stability, bending, tensile, compressive strength is very superior, heat resistance cold, electricity Insulation and resistance to atmospheric aging. Poor resistance to chemicals, poor fatigue resistance, easy to produce stress cracking, the output interface terminal circuit is generally made of carbon material, and there is no protective coating, by the gradual oxidation of the formation of air degradation layer, to the final lead to open circuit End of life, which is the most vulnerable to membrane switch failure, mainly the environment decided, regardless of use or not, physical damage time is 3 to 10 years. Generally applicable to the most extensive range, in addition to meet the requirements of most of the membrane switch panel, which glossy PC high transmittance can meet the requirements with a liquid crystal display window.
Sand surface polyester (PET) \ - 30 ~ 120 ℃ \ 0.1 ~ 0.2 smooth surface good chemical resistance, insoluble in general organic solvents, alkali. With excellent mechanical properties, electrical properties, rigidity, hardness and thermoplastic plastic in the largest strength and toughness, low water absorption, wear resistance, excellent friction resistance, high dimensional stability. Tensile strength comparable to aluminum, much higher than PC, PVC. Low because the surface is difficult to process into matte type, so the texture of PET is more expensive film switch circuit is the ideal substrate. Which has a texture PET suitable for the surface requirements of a higher or have a liquid crystal display window products.
