Light redirecting film(ZTT-FGM-J01)

To meet the cost reduction trend of photovoltaics, we launched CPC (coating-PET-coating) white reflective film products (ZTT-FGM-B01). The products are produced through the optical coating production line, and the white coatings and bonding layers are self-developed, which have excellent anti-UV performance and reflection gain; besides, with the mature manufacturing process and low manufacturing cost, the component gain is estimated by the component factory to have reached 0.8-1.2%.

Product  Features
  • Excellent UV resistanceTransparent weather resistance layer can protect the base layer free from discoloration under UV150kWh/m2;
  • Excellent reflection performancePositive reflectance (380-1100nm) more than 90%;
  • Excellent heat resistanceSelf-Developed high crosslinked film has passed 150℃/72h hot baking test
