Abstract: A solar panel backside film used in solar panel constructions. The film comprises a PET film having a net peak area as measured by differential scanning calorimetry of about ?15 J/g to about 5 J/g measured from the endpoint of the glass transition (Tg) up to 230° C., and an additive to opacify the PET film.

The solar panel backside film generally has a reflectivity of 50% or greater at a point in the visible range of light. Additionally, the solar panel backside film, when applied to a solar panel and exposed to 2000 hours at 85° C. and 85% relative humidity, does not result in exfoliation or visible cracks in the PET film.

Abstract: The invention provides a melt-processable conductive fluorothermoplastic composition comprising three components. The first component is at least one melt-processable, thermoplastic fluoropolymer component having its interpolymerized units derived from (i) at least 50 wt % of TFE, and (ii) one or more ethylenically-unsaturated monomers represented by the formulas (a) CF2?CF—Rf, (b) CF2?CF—O—Rf?, and (c) CH2?CR2. The thermoplastic fluoropolymer component is substantially free of interpolymerized units derived from VDF. The second component is from about 0.1 to about 10 weight percent of a hydrocarbon polymer, and the third component is from about 1 to about 20 weight percent of conductive filler. The invention also provides a method for making fluorothermoplastic compositions and shaped articles comprising a conductive fluorothermoplastic composition.
