EVA film for encapaulating solar modules. 1.Fast curing 2,Excelent UV, 3,damp and heat resistance, 4,long term performance
EVA film for solar cell
The main characteristics of EVA film follows:
1, Excellent durability, such as weather resistance, high-temperature and high humidity resistance, UV light resistance.
2, Excellent adhesion to glass, metal and plastics PET, TPT, Maintaining long term adhesion.
3, Excellent light transmittance and transparency.
4, Inactivation and harmless in solar cells during processing
5, Have a high cross linking rate after lamination.
6, Good encapsulating properties.
