Which are frequently used in the production of thin film panel substrate

Polycarbonate film (PC)

PC material has the distinguish of sand surface and smooth surface, PC material physical properties and chemical properties of composite indicator is good, the adaptive ink more widely, also isMembrane switchThe most popular material for panel layer application.Polycarbonate film with large temperature range (135 ~ 135 ℃), when the temperature or humidity changes, the performance of this kind of material change is not big, to ensure that the panel can be used in all kinds of instruments, all kinds of bad environment.The solvent is more sensitive, but the downside is strong solvation effect of solvent easily embrittlement, crack.

Polyvinyl chloride (PVC) film

PVC film material's price is lower, about half of PC material, when the product in the production of civil affordable, if choose PVC material, can reduce the production cost, PVC material has good ductility at the same time, can use cold processing three-dimensional graphic.Made from polyvinyl choride (PVC) heat resistance performance is poorer, especially under the condition of high temperature, the softening temperature of 59 ℃, elastic than polycarbonate film well.But it has the high elongation rate (130%), and because of its low price, it is suitable for use in general conditions.Polyester film (PET)State of the surface of PET film, are generally smooth transparent membrane, a few have the sand surface products such as the condition of the Japanese Kimoto KB products of the company.Elasticity of polyester film and temperature resistance are good, the price between the polycarbonate film and PVC film.But because of the thin film surface is difficult to processed into matte texture, more transparent sheet, at the same time, the surface of the polyester film for the vast majority of plastic cannot obtain the satisfactory result of printing ink, general to specific use special inks, to ensure good follow-up processing performance.Because of PET film general performance can be replaced by PC film, so the material used for panel is not too much, unless in some special occasions, such as the insulation, the springback, solvent resistance is under the condition of other film can't meet only a small number of applications.Press key words:Thin film panelThe last:Membrane switch interchange circuit network version of the productionNext up:Thin film panel industry its widespread use in the microwave oven
