Abstract: The invention relates to a solid porous article containing sub-micron functional additive particles held together using discrete sub-micron polymer binder particles. The porous article preferably also contains a majority of primary active particles in the 1 to 300 micron range. The solid porous articles are used to separate, precipitate, and/or trap components of a fluid that passes through the porous article. The solid porous articles are used to separate and trap components of a fluid that passes through the porous article. Preferred binders are polyvinylidene fluoride resins, such as Kyblock® resins from Arkema Inc.

Abstract: The invention relates to the use of a high performance thermoplastic polymer binder material for immobilizing adsorptive materials, such as activated carbon, in gas storage devices. The use of these binders, especially polyamide binders, polytetrafluoroethylene binders, or polyvinylidene fluoride binders such as Kyblock® resin, provides for high sorbent packing density, low fouling solid structure that maximizes the volume of gas to the volume of the storage space.

Abstract: The invention relates to chemically resistant structures that float on top of a liquid to reduce the level of evaporation from the liquid. The liquid could be in a small container or vat, or in a larger pool, pond, or reservoir. The structure is preferably a foamed material of a polyamide or fluoropolymer, or may be a hollow or foamed structure having a polyamide or fluoropolymer outer layer. The structures covering the liquid may consist of a single structure or two or more discrete structures that partially or fully cover the surface of a liquid. The covering is especially useful where the fluid contains toxic, reactive or corrosive substances. One preferred structure is a polyvinylidene fluoride foam structure (such as a KYNAR from Arkema Inc) at about 0.1-36 inches in length/diameter.

Abstract: The invention relates to very high melt flow fluoropolymer compositions, having low melt viscosities. The fluoropolymers have low molecular weights of from 5 kDa to 200 kDa and melt viscosities of less than 2 kilopoise (kP) at 232° C. and 100 s−1. One use for the high melt flow fluoropolymers is in the formation of very small diameters fibers, useful for melt-blown non-woven materials. Fiber diameters of less than 9 microns, and preferably 500 to 2000 nm can be produced.

Abstract: The invention relates to a porous separation article having a fluoropolymer or polyamide binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity. The separation article is useful in water purification, as well as in the separation of dissolved or suspended materials in both aqueous and non-aqueous systems in industrial uses. The separation article can function at ambient temperature, as well as at elevated temperatures.

Abstract: The invention relates to a dry free-flowing composite of a sub-micron polymer binder particles and interactive materials, and articles formed therefrom. The polymer particles are formed from a dilute latex polymer and blended with interactive materials, then the blend is spray-dried, to form a dry blend in which less than 10% of all polymer particles are in an agglomerated form. The polymer is preferably a polyvinylidene fluoride, such as Kyblock® PVDF from Arkema. The dry blend will be used to form articles and coatings by many means, for example forming a three dimensional article by heat and pressure, it can be redispersed into an aqueous coating composition, or can be electro-coated onto a substrate.

Abstract: The invention relates to a porous separation article having a fluoropolymer, polyamide, PEEK, or PEKK binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity.

Abstract: The invention relates to an article that has been obtained by the melt-process recycling of one or more multi-layer articles, where the multi-layer articles are composed of at least one melt-processible polyvinylidene fluoride layer. The composition of the invention is a compatible blend of the different layers from the multi-layer articles. The other layers of the multi-layer articles are also melt-processible, and include one or more layers chosen from: a) a melt-processible fluoropolymer of a different composition, b) a non-fluoropolymer, and c) a barrier layer. The composition is useful for forming an article in a melt-process operation. The composition may be used by itself, may be blended with other virgin or recycled materials, or may be used at low levels with melt-processible polymers as a process aid.
