DYMAT® HDPYE SX LDO
Extra moisture Barrier without Aluminuim
Coveme has developed a range of revolutionary backsheets specifically designed for photovoltaic modules that requires a high moisture barrier for different technologies. DyMat® barrier film backsheets are manufactured with an innovative integrated barrier layer which results in a low WVTR value and guarantee an excellent protection to the cells. These laminates have been specifically designed to be used in pv modules with heterojunction cells and floating systems with all types of cells. Furthermore, these backsheets, not having an aluminum layer, facilitate the production process of assembling the module. They are available with one or two PET layers, in white, transparent or black versions for installations up to 1500 VDC.
The range also includes a version of the revolutionary dyMat® ECO range composed of 33% recycled polyester (rPET) coming from post-consumer waste recycling: the dyMat® ECO PYE r33 MONO L PLUS .
