Polyvinyl alcohol is used to color film to create Polarizing Film (PVA). Heat resistance is one property of polarizing films that makes it possible for light with a specific oscillation direction to pass through. Polarizing films have a high level of durability, which allows them to keep their effectiveness and quality for an extended period of time. Polarizing Film features such as polarizing efficiency, color and transmittance are useful for applications such as light and stain leakage and reflection management. Reflective polarizing films with multi-layer can provide improved performance. They provide a wider spectrum of optical thicknesses, starting with smaller layers that can be utilized on mobile devices and other products where aesthetics matter while still blocking glare.
