Disclosed are various fluoropolymer blend combinations and multilayer articles comprising a blend in a first layer and a second layer comprising a polymer bonded to the first layer. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, and a second layer bonded to the first layer, the second layer comprising a partially-fluorinated thermoplastic polymer, a perfluorinated thermoplastic polymer, or a combination thereof. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, at least one of which comprises a partially-fluorinated thermoplastic polymer, and optionally at least one perhalogenated polymer, and a second layer bonded to the first layer, the second layer comprising an at least partially-fluorinated thermoplastic polymer. The invention also provides processes for preparing blended fluoropolymers and multilayer articles comprising a fluoropolymer layer.
A fluoropolymer comprising a blend of a substantially non-vinylidene fluoride containing partially fluorinated-thermoplastic and a perfluorothermoplastic.
A fluoropolymer comprising a blend two or more perfluoropolymers and a partially fluorinated-thermoplastic polymer.
A fluoropolymer comprising a blend of two or more different partially-fluorinated thermoplastic polymers having interpolymerized units derived from a substantial amount of VDF.
A fluoropolymer comprising a blend of three or more partially-fluorinated thermoplastic polymers.
A polymer composition comprising a blend of a polymer having a surface energy below about 20 mJ/m2 and a polymer having a surface energy having below about 25 mJ/m2, wherein the difference of the surface energy between the first layer and the second layer is from 1 mJ/m2 to 5 mJ/m2.
