B601RS EVA Solar Film
- B601RS is a black IR-reflective encapsulation film designed for use between the backsheet and solar cells in single and dual-glass PV modules.
- It enhances module appearance consistency while reducing adhesive overflow and grayish discoloration after lamination.
- With ≥70% reflectance in the 760–1100 nm range, it offers reliable peel strength, crosslinking performance, and electrical insulation, making it suitable for N-TOPCon, BC, and all-black aesthetic modules that require a black appearance, high reflective gain, and long-term reliability.
