摘要:
The invention describes a fluoropolymer laminate that includes a first substrate that can be a modified fluoropolymer having polar functionality and a second substrate. The substrates are laminated at an elevated temperature suitable for lamination to occur and then are subsequently treated with radiation, such as ultraviolet radiation, gamma radiation and/or electron beam.

The invention describes novel multi-layer films with a first outer layer comprising a fluoropolymer; a second interior layer comprising a polyester or a polycarbonate (or combinations thereof) and an acrylic or methacrylic compatibilizer or an alkyl tin oxide as a compatibilizer; and a third outer layer comprising a fluoropolymer or a polyolefin melt adhesive prepared by a coextrusion process.
摘要:
A multilayer film includes a functional portion including one or more layers, an adhesive layer overlying a major surface of the functional portion, and a fluoropolymer layer overlying a major surface of the adhesive layer opposite the functional portion. The fluoropolymer layer includes a fluoropolymer. The adhesive layer includes an adhesive and an ultraviolet radiation absorber.
摘要:
A roofing material includes a bitumen sheet material and a multilayer capping film. The multilayer capping film includes a first layer comprising a first fluoropolymer and a second layer underlying the first layer. The second layer includes at least 40 wt% of a second fluoropolymer and not greater than 60 wt% of an acrylic polymer. The second layer of the multilayer capping film overlies the bitumen sheet material and the first layer of the multilayer capping film forms an outer surface of the roofing material.
摘要:
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 olefmic polymer. The third layer includes a polymeric material and a filler.
