EVA Film for Encapsulating Solar Module
UV aging resistance, Resistance to temperature&Moisture.easily operate.Good light transmittance, anti-aging,long-time bonding.
Lushan™ EVA film is suitable for encapsulating silicon module, thin film module and BIPV module, which uses resins of VA content 30%-33% as its main material, provided with properties of high transmission, strong adhesion and long term performance. Thickness is from 0.3-0.8mm, while width is within 2000mm.The finished solar module is the cured battery plate which goes through trimming, cleaning, and installing aluminum alloy frame, testing and then packing.
