Various kinds of PMMA window covers for Touch Panel

①our original printing technology with strong sup-port by several ink makers enables us to control pre-cise thickness of print layers and make them thinner.

【Example】Black print 2 layers ≦10μmWhilte print 3 layers ≦18μm、　4layers≦22μm

②Our original processing technology with strong support by several plastic sheet makers enable us to produce only one product for each customer.

【Example】 Glass Substitute PMMA SheetA、Surface Hardness ≧6H B、High Unti -ScratchnessC、water-repellent/oil repellent or hydrophilic/oleophilicD、Glasslike Smooth TextureE、High Transmissivity
