产品描述
EVATANE® 28-25PV is a random copolymer of Ethylene and Vinyl Acetate made by high-pressure radicalar polymerization process.
APPLICATIONS
EVATANE® 28-25PV is exclusively dedicated to photovoltaic encapsulant films applications. The Vinyl Acetate content of EVATANE® 28-25PV brings high electrical insulation, transparency, flexibility and softness. In cross-linked formulations, it exhibits high dimensional stability, fast curing and easy lamination. EVATANE® 28-25PV is the material of choice for low PID EVA-based photovoltaic sheet.
