Superior weathering performance: it can resist long-term ultraviolet aging, 25 years service life for protecting backsheet.
Low water vapor transmission rate.
High reflection gain: the inner of the backsheet reflectivity can reach more than 85%, optimize the CTM of the modules greatly.
The product is specially designed for crystalline silicon photovoltaic modules
