The invention relates to sized reinforcing fibers that comprise a reinforcing fiber sized with a fluoropolymer. The fluoropolymer is functionalized and/or the reinforcing fiber is sized with a compatible functional non-fluorinated polymer that is compatible with the fluoropolymer. Functionalization of the fluoropolymer or the compatible non-fluorinated polymer provides enhanced properties, such as increased adhesion to the reinforcing fiber.

Effects and controller pedal board

The invention relates to an object or object part made from a composition comprising at least one fluoropolymer F, wherein: &#x2014;the at least one fluoropolymer F comprises vinylidene fluoride units and at least 30 wt. % of units derived from at least one monomer of formula (I): (I) CXX&#x2550;CXY, wherein each of X, Xand Xis independently selected from H, Cl, F, Br, I and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partly or fully halogenated and Y is an alkyl group comprising from 1 to 3 carbon atoms which is optionally partly or fully halogenated; &#x2014;the proportion of the at least one fluoropolymer F in the composition is at least 80 wt. %; and&#x2014;the viscosity of the composition is at least 1000 Pa&#xb7;s at a temperature of 230&#xb0; C. and at a shear rate of 100 s1.

Fluoropolymer thermoplastic elastomer

The invention relates to polyvinylidene fluoride (PVDF) copolymer compositions that have improved crosslinking efficiency and performance. The PVDF copolymer contains a high level (&#x3e;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&#xb0; C. and 100 sec&#x2212;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.

Cross-linked thermoplastic polyvinylidene fluoride compositions

The invention relates to fluoropolymer composites having a fluoropolymer matrix containing a functionalized fluoropolymer composition, and reinforced with fibers. The fibers can be chopped fibers, long fibers, or a mixture thereof, and the fluoropolymer matrix preferably is based on polyvinylidene fluoride. Any type of fibers, sized or unsized may be used with the functionalized fluoropolymer matrix composition to form the fluoropolymer composite.

High strength polyvinylidene fluoride composite

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.

Fluoropolymer blend

A pedal board apparatus includes a single-tier, a double-tier, and a triple-tier variant, wherein each tier includes a deck having a top surface and an opposing bottom surface. Each deck is bound by a first sidewall and a second sidewall. Each sidewall comprises a plurality of ports providing ingress and egress for cables and/or connectors. Each deck has an incline wherein the first sidewall has a greater height than the second sidewall, and each intermediate sidewall has a height greater than the second sidewall. The apparatus may include at least one handle disposed along the deck.

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&#xae; 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.

3-D printed fluoropolymer structures

Fibers sized with a coating of amorphous polyetherketoneketone are useful in the preparation of reinforced polymers having improved properties, wherein the amorphous polyetherketoneketone can improve the compatibility of the fibers with the polymeric matrix.

Fibers sized with polyetherketoneketones

The invention relates to the use of chopped fibers in thermoplastic composite compounds, and in particular to thermoplastic fluoropolymer compounds. The fluoropolymer matrix contains thermoplastic fluoropolymers that have been grafted with a carboxylic polar functionality, such as KYNAR ADX&#xae; polymer from Arkema. The chopped fiber&#x2014;grafted fluoropolymer composite has increased tensile and flexural strength compared to fluoropolymer compounds that contain no grafted carboxylic grafted fluoropolymer.

High strength polyvinylidene fluoride based reinforced compounds

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.
