Coveme Backsheet for PV module protection
High grade polyester based backsheets.
dyMat®PYE is an innovative laminate based on two layers of high performance polyester film. The cell side is treated with a special thick primer which provides extremely high bonding to EVA. This primer can be supplied in different colours and in transparent finishing. dyMat® PYE backsheet is the right choice for outstanding durability under extreme conditions.
Recently Coveme has developed DyMat PYE 3000, a new high grade PET backsheet that resists to over 3000h DHT (Damp Heat Test).
