Title
(EN) POLYMERIC COMPOSITIONS COMPRISING VDF POLYMERS AND GRAPHITE
(FR) COMPOSITIONS POLYMÈRES COMPORTANT DES POLYMÈRES DE VDF ET DU GRAPHITE
Abstract
(EN)
The present invention relates to a polymeric composition comprising: one or more vinylidene fluoride (VDF) polymers, from 1 to 100 parts, preferably from 2 to 50 parts, more preferably from 2 to 30 parts, even more preferably from 3 to 20 parts by weight for 100 parts of VDF polymer of a plurality of particles of graphite, wherein said particles of graphite have an D90 particle size as measured with laser scattering of less than 50µm, preferably from 2 to 30 µm more preferably from 2 to 20 µm, even more preferably from 2 to 10 µm and a BET specific surface of from 10 to 50 m2/g, preferably 15 to 35 m2/g. The invention also relates to tubular articles comprising the composition and to their use in oil and gas operations.
