Product Specifications

The independently developed inorganic nano-vapor deposition technology and bottom-layer-coating moisture-heat aging resistance technology endow the high-barrier backsheet with low water vapor transmission rate and high moisture-heat aging resistance retention. It can be widely applied to N-type battery modules, ensuring the power generation efficiency and long-term reliability of N-type battery modules.

Product Features:

High water resistance: Water vapor transmission rate ≤ 0.4 g/m²·d at 38°C and 90% RH.
High water resistance retention: After double 85 aging, the water vapor transmission rate retention is ≤ 0.6 g/m²·d.
High weather resistance: Meets the long-term service life requirements of modules.
