  • Process for manufacturing fluoropolymer composites
    Patent number: 10138161
    Abstract: The present invention pertains to a process for manufacturing a fluoropolymer composite, said process comprising the following sequential steps: (i) providing an aqueous latex comprising from 10% to 40% by weight, preferably from 15% to 35% by weight of at least one fluoropolymer comprising recurring units derived from vinylidene fluoride (VDF) [polymer (VDF)]; (ii) up-concentrating the aqueous latex provided in step (i) thereby providing an up-concentrated aqueous latex comprising from 45% to 60% by weight, preferably from 45% to 55% by weight of at least one polymer (VDF); (iii) contacting one continuous fiber or a bunch of continuous fibers with the up-concentrated aqueous latex provided in step (ii); (iv) squeezing the impregnated fibrous material provided in step (iii); (v) drying the squeezed fibrous material provided in step (iv), typically at a temperature comprised between 100° C. and 120° C.; (vi) baking the dried fibrous material provided in step (v) at a temperature comprised between 190° C.
