Abstract: The present invention relates to a photovoltaic module backsheet comprising, in order: photovoltaic module backsheet comprising a functional layer and a weather-resistant layer, wherein the backsheet is free of fluorinated polymers, characterized in that: i) the functional layer comprises a blend of polyethylene and a polyethylene copolymer, wherein at least 50 wt. % of the functional layer is polyethylene; and ii) the weather-resistant layer comprises, a first sub-layer facing the functional layer and a second sub-layer, wherein a) each of the first sub-layer and the second sub-layer comprise at least 50 wt. % polypropylene; and b) the second sub-layer has a lowest glass transition temperature (Tg) below ?40° C. The present invention also relates to a process for producing the backsheet and a photovoltaic module comprising the backsheet according to the present invention.

Abstract: The present invention relates to a multi-layer material sheet comprising an NIR-reflective, translucent polymeric layer having a reflectance of more than 20% of all light with a wavelength from 750 nm to 1000 nm and a transmission of more than 50% of all light with a wavelength from 380 nm to 750 nm and an NIR-reflective, colored polymeric layer having a reflectance of more than 25% of all light with a wavelength from 1000 nm to 2100 nm. The present invention also relates to a backsheet suitable for use in a photovoltaic module, said backsheet comprising said multi-layer material sheet; and to a photovoltaic module comprising said backsheet.

Abstract: The invention relates to thermosetting powder coating compositions comprising an unsaturated resin comprising ethylenic unsaturations and a thermal radical initiator comprising a first thermal radical initiator, wherein the first thermal radical initiator is a methyl-substituted benzoyl peroxide abbreviated herein as MBPO. The invention further relates to a process for making said thermosetting powder coating composition and processes for coating an article with said thermosetting powder coating composition. The invention further relates to a cured thermosetting powder coating composition derived upon curing of the thermosetting powder coating composition of the invention. The invention further relates to an article having coated thereon said thermosetting powder coating composition as well as to an article having coated and cured thereon said thermosetting powder coating composition.
