What are the commonly used materials for membrane switches and membrane panels in production? Xiao Bian interviewed the staff of Shanghai Xiangming Membrane Switch Co., Ltd. and asked him to introduce it to everyone.
Because the general performance of PET film can be replaced by PC film, it is not used in the case of panel materials, except in some special occasions, such as insulation, rebound, solvent resistance and other films can not be satisfied There are only a few applications under the circumstances.
However, as a glossy material, once printed on the back side, the color will appear brighter and brighter. In the case where the decorative requirements are strong and do not need to be touched frequently, the glossy material is often chosen to make the panel, or because of some display areas such as Considering the special needs of LCD liquid crystal displays, the use of glossy materials is advantageous.
The comprehensive index of physical properties and chemical properties of PC materials is better, and the inks that are adapted to it are also more widely used. It is the most commonly used material for membrane switch panel layers. The PC material has a difference between sand and glossy surfaces. The reason for choosing the sand surface material is that the use of the membrane switch is mostly an electronic machine product. The panel used as a control and control system does not want to be disturbed by light, and the sand surface is a surface. Only diffuse reflection, will not produce a bright reflection; at the same time, because the surface was disordered sand particles, with the role of masking scratches, on the contrary, the glossy material does not have the above characteristics.
The price of PVC film material is relatively low, which is about one-half of that of PC. When producing civilian-used products, if PVC material is selected, the production cost can be reduced. At the same time, the ductility of PVC material is better and cold pressing can be used. Stereoscopic graphics. The general thickness of glossy PVC sheet is 0.5 mm or more. Both sides are protected by PET or water adhesive tape. Most of them are used to make decorative panels. The thickness of PVC material on the sand surface is generally less than 0.3 mm. It is generally of a fixed length. Sheet supply, no coils.
