DYMAT® PYE MONO
Best selling and Single layer
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. The dyMat® PYE MONO C is available with white, black or black high reflectivity coating.
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 
is the very first backsheet made with rPET availabe on the market today.
