The UV resistant " HOSTAPHAN ® Protective Films" from Mitsubishi Polyester Film GmbH are biaxially oriented films made from polyethylene terephthalate (PET). These polyester films offer good weathering resistance and very high absorption of UV radiation. All ultraviolet blocking types, with the exception of the white type UVO, show a high transmission in the visible and almost no transmission in the ultraviolet light region.
Other important features of these UV-stable polyester films include high mechanical strength and good dimensional stability. They also enable good adhesive bond strength to be achieved in coating, printing and laminating.
This glass clear film for outdoor applications and UV absorption has a very smooth, glossy surface.
This highly transparent PET film allows good adhesive bond strength to be achieved with coatings and vacuum metallized layers. The surface of HOSTAPHAN ® RUVK is also highly glossy.
HOSTAPHAN ® RUHS is a transparent, coextruded film with two different surfaces. One side of this film is heat-sealable to PET and to itself. The other, non-heat-sealable side provides optimal winding properties.
HOSTAPHAN ® MUSI is a biaxially oriented, coextruded matte and UV-stabled PET film. It has an excellent sealability against PET on one side, a low glose surface on the other side and a very high resistance against and high absorption of UV-radiation.
HOSTAPHAN ® UVO combines extremely low transparency with a high degree of whiteness. This film is especially weather resistant in outdoor applications.
HOSTAPHAN ® RUF is a highly transparent, glossy film with excellent flame retardant and UV protective properties.

The long-term weathering resistance of our UV-resistant "HOSTAPHAN ® Protective Films" in outdoor applications has been studied in a climate test according to ISO 4892 in a Xenon weather-o-meter.
This accelerated weathering test about 10.000 h simulates approx 10 years outdoor exposure under central European conditions. An unstabilized film is completely destroyed over this period of time.
Please note that when our "HOSTAPHAN ® Protective Films" are combined with other materials or articles, the performance of the final product depends on all components and the geometry. Rigorous qualification and safety testing of the final product is always necessary, as unexpected interactions could occur.
