EVA Solar Film
We manufacture high-performance EVA (Ethylene Vinyl Acetate) encapsulation films designed for long-term protection, high transparency, anti-PID, and excellent adhesion in photovoltaic modules.
Main Features of Our EVA Solar Films
Excellent Optical Transparency
- Light transmittance can exceed 91%, reducing optical loss and improving module power output.
Strong Adhesion Performance
- Provides excellent adhesion to glass, backsheet, and solar cells, reducing the risk of delamination.
Fast & Stable Crosslinking
- Compatible with mainstream lamination processes, offering high crosslinking efficiency and stable lamination performance.
High Anti-PID Performance
- Volume resistivity reaches up to 1 x 10^15 Ω·cm, suitable for high-system-voltage PV modules.
Customizable Formulation
- Customized solutions available for different photovoltaic single-glass and double-glass modules.
Long-Term Weather Resistance
- Excellent resistance to UV exposure, damp heat, and thermal aging, ensuring long-term module durability and service life.
