Uses: Widely used in membrane switches, instrument switches, brackets, commercial and communication equipment, POP display panels, medical diagnostic equipment, automotive instruments, etc. PC film (also called polycarbonate film, because the thickness is relatively thin, generally called film or sheet below 1.0mm, generally called pc board above 1.0): PC film thickness is between 0.125 and 1.0, with smooth and frosted , There are coils and sheets. There are sheets and coils. The sheets are one by one. The coil has a certain width and a length of several hundred meters. The general thickness is: 0.125, 0.175, 0.2, 0.25, 0.3, 0.375, 0.5, 0.7, 0.8, 1.0. Among them, 0.125, 0.175, 0.2, 0.25, 0.3, 0.375, etc. are mainly coiled materials, while other thicknesses are mainly sheet materials
