Abstract: The invention pertains to a fluoropolymer composition comprising certain thermoprocessable tetrafluoroethylene copolymers, certain amounts of graphite particles, to the use of this latter for manufacturing shaped articles, and to shaped articles therefrom, including components for heat exchangers, e.g. conduits used for cooling and/or heating fluids, e.g. gas flows in flue gas desulphurization units.

Abstract: The present invention pertains to a process for the manufacture of a dense film. The process includes processing, in a molten phase, a solid composition [composition (C)] comprising; at least one vinylidene fluoride (VDF) fluoropolymer comprising one or more carboxylic acid functional end groups [polymer (F)], at least one poly(alkylene oxide) (PAO) of formula (I): HO—(CH2CHRAO)n—RB??(I) wherein RA is a hydrogen atom or a C1-C5 alkyl group, RB is a hydrogen atom or a —CH3 alkyl group and n is an integer comprised between 2000 and 40000, preferably between 4000 and 35000, more preferably between 11500 and 30000, and -optionally, at least one inorganic filler [filler (I)]; thereby providing a dense film having a thickness of from 5 ?m to 30 ?m. The present invention also pertains to the dense film provided by this process and to the use of the dense film as dense separator in electrochemical devices.

Abstract: The invention pertains to a white pigmented fluoropolymer composition comprising certain thermoprocessable tetrafluoroethylene copolymers, certain amounts of specific PTFE micropowders, which possesses advantageous properties for being used for manufacturing shaped articles, and to shaped articles therefrom, including components of light emitting apparatuses, e.g. LED assemblies, including those having junctions emitting in the UV region.

Abstract: The present invention pertains to a process for the manufacture of a dense film, said process comprising, preferably consisting of the following steps: a) providing a solid composition [composition (C)] comprising, preferably consisting of: at least one vinylidene fluoride (VDF) fluoropolymer comprising one or more carboxylic acid functional end groups [polymer (F)], at least one poly(alkylene oxide) (PAO) of formula (I): HO—(CH2CH RAO)n—RB, wherein RA is a hydrogen atom or a C1-C5 alkyl group, RB is a hydrogen atom or a —CH3 alkyl group and n is an integer comprised between 2000 and 40000, preferably between 4000 and 35000, more preferably between 11500 and 30000, and optionally, at least one inorganic filler [filler (I)]; and b) processing said composition (C) in molten phase thereby providing a dense film having a thickness of from 5 ?m to 30 ?m. The present invention also pertains to the dense film provided by said process and to use of said dense film as dense separator in electrochemical devices.
