ISARD Encapsulation Film Series
ISARD 3280 second-gen PO encapsulation film
ISARD 3280 polyolefin elastic co-extruded encapsulation film is a cross-linked composite polyolefin PV encapsulating material that is produced by mixing polyolefin copolymer resin with various necessary additives in certain mixing ratio. It is characterized by excellent moisture insulation, the ability to firmly bind the glass and backsheet durably, the ability to protect and fix solar cells, excellent resistance to dampness, heat and ultraviolet ageing, and long stable resistance to PID.
