According to reports, Evatane33-45PV containing a large number of EVA (ethylene – vinyl acetate copolymer) copolymer grades of the special, which is specifically for photovoltaic solar panels and developed. This vinyl acetate containing 18 ~ 42 of the new brand, is designed as a sealing material (crystalline silicon or thin film) design, and this material can be used to produce solar panels. Solar panels for vatane33-45PV has good optical properties and good light transmission, at the same time have a good ability to cross-linking and processing properties of the resin before the end of the developer program will also develop a new Evatane grades, but also in the field of optoelectronics.
