Alishan Low-Acid EVA

Alishan Low-Acid EVA is a next-generation encapsulant film specially formulated to address the core limitation of conventional EVA—acetic acid generation. This acid causes corrosion, yellowing, and power loss over time, particularly under damp-heat conditions. By drastically minimizing acid formation, Alishan Low-Acid EVA enhances module stability and longevity, especially for advanced cell types like TOPCon and HJT.

Ultra-Low Acetic Acid Formation
Superior Resistance to Damp Heat (85°C/85% RH)
Excellent PID Resistance
High Optical Transparency
Strong Adhesion to Glass and Backsheet
Compatible with TOPCon, HJT, and Bifacial Technologies

Alishan Low-Acid EVA combines the processing ease of standard EVA with significantly better chemical stability and field reliability. It retains EVA’s manufacturing compatibility while eliminating the long-term degradation risks associated with acid-induced corrosion.

Acid Suppression: Alishan Low-Acid EVA features a specially engineered formulation that limits the breakdown of EVA into acetic acid. This reduces internal corrosion of metallization (Ag, Cu, Al) and ensures that solar modules maintain performance over decades.

Damp-Heat Durability: In damp-heat testing beyond 1000 hours, Alishan Low-Acid EVA showed minimal discoloration, no delamination, and significantly lower power loss than standard EVA. This makes it ideal for use in humid, tropical, or coastal environments.

PID Stability: Its low-acid chemistry supports high insulation resistance, preventing leakage currents and enabling modules to pass rigorous PID tests—a must for large-scale, high-voltage solar plants.

Cell Compatibility: Alishan Low-Acid EVA is designed for next-gen cells like TOPCon and HJT. It safeguards delicate layers like tunnel oxides and TCOs from acid-related damage, ensuring consistent power output over time.

Efficient Lamination: With a lamination profile similar to traditional EVA, manufacturers can integrate Alishan Low-Acid EVA into existing lines without process changes, making it both reliable and scalable.

With its balanced performance and durability, Alishan Low-Acid EVA offers module manufacturers a smart alternative—greater reliability and longer lifespan without increased cost. It’s the ideal choice for the future of solar.
