Abstract:
A roofing material includes a first layer including a fluoropolymer, a second layer directly bonded to and directly contacting the first layer, and a third layer underlying the second layer. The second layer includes an unfunctionalized olefinic polymer. The third layer includes a polymeric material and a filler.
A multilayer polymer film includes first and second polymer layers. The first polymer layer includes a first ultraviolet radiation absorber. The second polymer layer overlies the first polymer layer and includes a second ultraviolet radiation absorber. The first ultraviolet radiation absorber has a peak absorbtivity wavelength less than 300 nm and the second ultraviolet radiation absorber has a peak absorbtivity wavelength greater than 300 nm.

Abstract:
Aspects of the invention are found in a multilayer film comprising a first polymer layer and a second polymer layer. The first polymer layer comprises a blend of a first fluoropolymer having a first average molecular weight and a second fluoropolymer having a second average molecular weight. The first average molecular weight is greater than the second average molecular weight.
