Abstract: The present patent application relates to the use of non fluorinated aromatic polymers as additives for fluorinated lubricants.

Abstract: A thermal management system is disclosed, in particular a battery thermal management system, as well as a flame resistant heat transfer tube for use in said thermal management system. The flame resistant heat transfer tube comprises a composition which contains at least one polyphenylsulfide polymer, at least one polyphenylsulfone polymer, and at least one thermoplastic elastomer containing epoxy functional groups. A method of cooling a battery and/or operating a battery comprising passing a heat transfer fluid, preferably a water/ethylene glycol mixture, in such a flame resistant heat transfer tube.

Abstract: Described here are multilayer tubes including a plurality of layers. The multilayer tubes include an outermost layer, including a first polyarylene sulfide (“PAS”) and from 5 wt. % to 30 wt. % of an impact modifier. The multilayer tubes also include an innermost layer including a second PAS and from 0.1 wt. % to 10 wt. % of an electrically conductive filler. Significantly, each layer in the multilayer tube comprises a PAS. The outermost layer is the sole layer comprising an impact modifier and the innermost layer is the sole layer comprising an electrically conductive filler. At least in part because of compatibility of PAS based materials with one another for interfacial bonding, the multilayer tube is free of tie layers.

Abstract: The invention pertains to an insulating assembly part for an electrochemical cell comprising one or more fluoropolymers, said fluoropolymers comprising —87-99% by moles of recurring units derived from tetrafluoroethylene (TFE) —1-13% by moles of recurring units derived from perfluoro methyl vinyl ether (PMVE) —0-3% by moles of recurring units derived from perfluoropropyl vinyl ether (PPVE) and having a melt flow rate (MFR) of from 40 to 300 g/10 min (measured at 372° C. under a 5 kg load).
