DYMAT® PYE MONO

Single layer pet

GREEN BLACKSHEET

This new generation of backsheet from Coveme is based on a single PET layer (Mono Layer) that features superior resistance to UV and hydrolysis thanks to its bulk technology. Contrarily to the co-extrusion technology, the bulk technology features the UV protection all across the whole thickness of the single PET layer. Coveme’s monolayer backsheet shows excellent performances in the combined UV+DHT tests as well as it features an intrinsic high reflectivity. Available also in transparent version for bifacial modules.
