Photovoltaic Grade EVA Color Masterbatch
High-purity EVA masterbatch for solar PV encapsulant films.
Our photovoltaic EVA masterbatch is a high-purity formulation designed for solar PV encapsulant films. With ultra-low volatile content and excellent UV/weathering resistance, it is suitable for crystalline silicon and thin-film solar module encapsulation.
Product Features
- Ultra-low volatile content (< 0.1%)
- Excellent UV resistance
- High light transmission
- No PID (Potential Induced Degradation) contribution
- Long-term weathering stability
