The UPCw2 backsheet, launched by Lucky Film, features a new structure. Its weather-resistant layer utilizes a self-developed U-film, providing excellent weather resistance, low temperatures tolerance, high barrier properties, and abrasion resistance. The overall DTI of the backsheet is >450 μm, meeting the requirements for 2000V photovoltaic power generation systems.

Product Features:

1. High Voltage Resistance: With a DTI >450 μm, it meets the demands of 2000V photovoltaic power generation systems, supporting cost reduction in solar power stations.
2. High Barrier Property: Water vapor transmission rate <0.8 g/m²·d, ensuring TOPCon cells are protected from moisture corrosion.
3. High Heat Resistance: The U-film is deeply reinforced, withstanding high-temperature hotspot testing without cracking.
4. Superior Weather Resistance: Excellent environmental aging performance, offering weather resistance comparable to fluorine film backsheetproducts.
