The first fluoropolymer has from 0 to 30 weight percent of a monomer J selected from the group consisting of hexafluoropropene (HFP), fluorinated or perfluorinated vinyl ethers, 2,3,3,3-tetrafluoropropene, trifluoropropene, 1-chloro-3,3,3-trifluoro propene or combinations thereof. The second fluoropolymer has at least 30 weight percent, preferably at least 35 weight percent, of monomer T selected from the group consisting of hexafluoropropene (HFP), fluorinated or perfluorinated vinyl ethers, 2,3,3,3-tetrafluoropropene, trifluoropropene, 1-chloro-3,3,3-trifluoro propene or combinations thereof.

Abstract: The invention relates to fluoropolymer filament for use in 3-D printing, and 3-D printed fluoropolymer articles having low warpage, excellent chemical resistance, excellent water resistance, flame resistance, and good mechanical integrity. Additionally, the articles of the invention have good shelf life without the need for special packaging. In particular, the invention relates to filament, 3-D printed polyvinylidene fluoride (PVDF) articles, and in particular material extrusion 3-D printing. The articles may be formed from PVDF homopolymers, copolymers, such as KYNAR® resins from Arkema, as well as polymer blends with appropriately defined low shear melt viscosity. The PVDF may optionally be a filled PVDF formulation. The physical properties of the 3-D printed articles can be maximized and warpage minimized by optimizing processing parameters.

Abstract: The invention relates to a radiation curable adhesive system for use in bonding a high thermal deformation temperature layer to a UV opaque, pigmented or non-pigmented fluoropolymer film The radiation curable adhesive system uses an adhesive composition optimized for cure using long wavelength UV energy. The adhesive system may also be optimized for curing by LED or e-beam radiation. The system is designed for curing through a UV opaque fluoropolymer film—and especially where titanium dioxide is used as the pigment. A preferred multilayer film structure is a polyvinylidene fluoride (PVDF)/curable adhesive/polyester terephthalate (PET) structure. This film structure is especially useful as a backsheet for a photovoltaic module.

Abstract: The present invention relates to the preparation of a thermoplastic fluoropolymer blend composition exhibiting improved mechanical properties upon fabrication. The fluoropolymer blend composite on is produced by blending an emulsion latex of fluoropolymer (A) with an emulsion latex of fluorinated copolymer (B). Copolymer (B) emulsion has a small particle size, super high MW, and a low degree of crystallinity. The blending of the latex emulsions results in a morphology with small particles of copolymer (B) uniformly distributed within a matrix of fluoropolymer (A) in a manner that could not be achieved by a mere melt blending of the tow components.

Abstract: The invention relates to polyvinylidene fluoride (PVDF) copolymer compositions that have improved crosslinking efficiency and performance. The PVDF copolymer contains a high level (>14 and preferably greater than 16 wt %) of a fluorinated comonomer, and has a high molecular weight as measured by the melt viscosity at 230° C. and 100 sec−1 of 18 to 40 kpoise. The composition can be effectively cross-linked with a low level radiation (high cross-linking efficiency). The cross-linked composition is useful in high-temperature applications, such as automotive wire and cable, and heat shrink tubing.

Abstract: Hollow fiber membranes having improved toughness and durability are prepared using a vinylidene fluoride polymer-containing component, such as Kynaro resins, having relatively low crystallinity. One aspect of the invention provides a membrane in the form of a fiber, wherein i) the fiber has a porous wall of a polymeric component enclosing a central hollow space extending the length of the fiber, ii) the polymeric component has a crystallinity as determined by wide angle x-ray diffraction of less than about 35%, iii) the polymeric component is comprised of at least one homopolymer or copolymer of vinylidene fluoride and iv) the membrane has an energy to break of at least about 0.5 J per square mm of membrane cross section.
