    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: Disclosed is a thermoplastic elastomer composition comprising a blend of at least two fluoropolymers. 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 blends containing polymers of vinylidene fluoride, having low ductile-brittle transition temperatures and having excellent low temperature impact properties while maintaining the positive aspects of unmodified vinylidene fluoride-containing polymers. The blends of this invention are produced by adding a core-shell impact modifier (CSIM) comprised of a polysiloxane core and a shell compatible with vinylidene fluoride-containing polymer. The blends are further characterized by the presence of a heterogeneous copolymer composition comprised of two or more distinct phases and/or at least one flame and smoke suppressant. The preparation of these new blends can be done by conventional thermoplastic compounding techniques such as twin screw compounding; alternatively, the CSIM can be introduced earlier, such as in the latex. The unique properties of the new blends make them useful in end-use applications where those properties provide performance advantages, such as in wires & cables and in oil and gas applications.

    Abstract: A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently C-A or N, so long as at least one X is N but no more than two of X are N. Moreover, A is H, cyano or an electron donating group that: (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring; or (2) is an aryl group or alkyl group. Further, each R is independently H, an alkyl group, or aryl group and each R′ is independently an alkyl group or an aryl group.
