Patent application numberDescriptionPublished
200900052891,1,1,3,3- Pentafluorobutane Composition - The invention relates to the field of solvents. The invention relates more particularly to a composition based on 1,1,1,3,3-pentafluorobutane (HFC-365 mfc). The present invention also relates to a process for dissolving oil.01-01-2009
20100179237THERMOPLASTIC FOAM BLOWING AGENT COMBINATION - A blowing agent for thermoplastic foams such as extruded polystyrene foam is disclosed. The blowing agent is a blend of a low solubility blowing agent, such as 1,1,1,2-tetrafluoroethane, and a dichloroethylene such as trans-1,2-dichloroethylene. The blowing agent combination enhances processability of thermoplastic foam.07-15-2010
20110006248BLOCK COPOLYMER OIL RETURN AGENTS - The present invention relates to fluorine free polymeric oil-return agents that increase the miscibility of lubricants such as mineral oils and/or oxygenated lubricants with refrigerants in order to improve oil return and system performance of refrigeration systems. It was discovered that fluorine free block copolymers having a block compatible with the oil phase, and at least one block compatible with the refrigerant phase can effectively compatibilize lubricating oils with HFC and HFO refrigerants.01-13-2011
20110287255HIGH PERFORMANCE FIBERS - Heat-resistant, high strength fibers useful in a wide range of end-use applications are prepared using a polymeric composition containing polyetherketoneketone and mineral nanotubes.11-24-2011
20110294943FIBERS SIZED WITH POLYETHERKETONEKETONES - 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.12-01-2011
20110315263FLEXIBLE COMPOSITE PIPE - A flexible composite pipe useful in off-shore oil and gas well operations is provided which contains at least one polymer layer such as an internal pressure sheath, an intermediate sheath, an anti-wear layer and/or an outer sheath, wherein the polymer layer is formed using a polyetherketoneketone or mixture of polyetherketoneketones having a controlled ratio of different isomeric repeating units.12-29-2011
20120015577POLYETHERKETONEKETONE NONWOVEN MATS - The invention provides nonwoven mats comprising polyetherketoneketone fibers or mixtures thereof. Also provided are filters, textiles, blankets, and insulation prepared from polyetherketoneketone nonwoven mats, as well as methods for manufacturing the same.01-19-2012
20120024412ARTICULATED PIPING FOR FLUID TRANSPORT APPLICATIONS - An articulated pipeline assembly for the transport of fluids including a fluid conduit for transporting fluid and an articulating shell assembly that is positioned to encapsulate the fluid conduit. The articulating shell assembly includes a plurality of articulating shell segments, each articulating shell segment comprising both a ball and a socket, wherein the ball of each articulating shell segment is engaged with a socket of an adjacent articulating shell segment to form a ball and socket joint. Each articulating shell segment is configured to rotate with respect to an adjacent articulating shell segment by virtue of the ball and socket joint.02-02-2012
20120028036ASSEMBLIES CONTAINING POLYETHERKETONEKETONE TIE LAYERS - Tie layers comprised of amorphous polyetherketoneketone are used to join substrates to form laminates and other assemblies.02-02-2012
