  • High performance sorption binder for gas phase storage devices
    Patent number: 10532340
    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.

  • Expanded polymer powders
    Patent number: 10526464
    Abstract: The invention relates to small expanded polymer powder particles, and uses thereof. The expanded powder particles are formed by a non-melt process, resulting in individual expanded particles in the 5 to 100 micron range. The expanded powder particles are especially useful in cosmetic applications, as they provide a softer feel than a powder, and have a much higher surface area, making them highly absorbent for removing liquids and oils, as well as for use as excellent carriers and release agents for active ingredients.

  • Heat treated polymer powders
    Patent number: 10519309
    Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.

  • Voided latex particles
    Patent number: 10442882
    Abstract: A process for forming voided latex particles is improved by combining swelling and polymerization of an outer shell into a single step. The process includes contacting multi-stage emulsion polymer particles comprising a core, at least one intermediate shell, with a swelling agent, and polymerizing an outer shell after said contacting with swelling agent wherein the core and the at least one intermediate shell are contacted with swelling agent in the presence of less than 0.5% monomer based on the weight of the multi-stage emulsion polymer particles, and substantially all of the swelling occurs during polymerization of the outer shell.

  • Porous separation article and separation method
    Patent number: 10434478
    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. 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.

  • Process for coating a glass substrate with an aqueous fluroropolymer coating
    Patent number: 10392298
    Abstract: The invention relates to an intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance. The coating is an environmentally friendly aqueous, fluoropolymer coating composition. The coating process involves applying a polyurethane primer to the glass substrate, and partially, but not completely crosslinking this primer coating. An aqueous hydroxyl-functional fluoropolymer coating is then applied to the partially cross-linked primer coating, and the coating allowed to fully cure. The invention also relates to the intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance.
