Casting process allows pigments to be built-in during manufacture, so vinyls come in a wide range of sunlight resistant colors. Typically printed subsurface, so graphics are protected from scratching and environment. Easier to print and cut than polyester. Polycarbonate can be extruded with velvet texture and other finishes that are unavailable in polyester. Cracks when subjected to flexing over time when used for a membrane key pad.
Coating adds scratch resistance and chemical resistance to glass clear polycarbonate.
Used for overlays with glass clear LED and LCD windows. Roughly doubles the cost compared to standard polycarb. Identical in appearance to velvet polycarbonate, but softens at 175 F. Used in place of velvet polycarbonate when cost is critical and temperature resistance is not. Poor dimensional stability makes it inappropriate for tight fit in recessed areas, or tight print to die registration. Better chemical resistance and scratch resistance than non-hardcoat polycarbonate.
