OPTICAL FILM Applications
ZeonorFilm® isotropic and retardation films exhibit excellent transparency, dimensional stability, and light transmission for display light management applications. Applications include polarizers and support films in polarizers, LCD panels, touchscreen, mobile phone, and electronic paper applications. Additionally, ZeonorFilm can be used for bio-diagnostic applications.
• High transparency • Low birefringence
• Low water absorbency • Low moisture permeability
• High heat resistance • Low gas emissions

LOW WATER ABSORPTION
ZeonorFilm absorbs virtually no moisture and shows no dimensional changes even under conditions of high temperature and humidity. This allows for a reduction in white and black spots on colored displays.
OPTICAL ISOTROPY
ZeonorFilm exhibits uniform retardation across a wide incidence (viewing) angle.
HIGH HEAT
ZeonorFilm has excellent dimensional stability when exposed to elevated temperatures (120°C). This heat resistance allows ZeonorFilm to be used in demanding applications including mobile phones and automotive displays where long-term heat exposure is common.
HIGH TEMPERATURE/HUMIDITY
ZeonorFilm absorbs virtually no moisture and shows minimal dimensional changes even under conditions of high temperature and humidity.
WAVELENGTH DISPERSION PROPERTY
ZeonorFilm exhibits extremely flat wavelength dispersion making it well-suited for broad wavelength plates.
HIGH TRANSPARENCY
ZeonorFilm exhibits high transparency (92% light transmittance) and excellent turbidity (haze value <0.1%), for enhanced brightness.
LOW BIREFRINGENCE
ZeonorFilm has lower birefringence as compared to competitive optical films including PET, PC, and TAC.
