HANCIIEN Where PFAS is used in hydraulic cylinders Directly used inside the cylinder - used Materials are PTFE, FKM, FFKM, FEPM, FVMQ, PCTFE, TFM, PVDF, PFA, FEP - In seals such as O-rings, piston and rod seals, wiper rings - In guiding systems such as guide bands/ wear rings - In sliding coatings of the piston rod or the covers Installed on the cylinder - Electronic components (proximity switches, displacement sensors, ...) - Cables Why PFAS? - High temperature > 150C - Better sliding properties for higher energy efficiency o Less friction o Less wear o Less leakage o Longer lifetime PFAS replaceable? - For seals with temperature application: o No alternative known - For seals without temperature application: o with significantly worse tribological properties o also worse energy efficiency, etc. o No alternative known Annex PFAS used in hydraulic cylinders Hanchen Wag 22.09.2023 Herbert Hanchen GmbH Brunnwiesenstr. 3 73760 Ostfildern Germany Fon +49 711 44139-0 Fax +49 711 44139-100 @haenchen.de www.haenchen.de Amtsgericht Stuttgart HRB 213857 USt-IdNr.: DE337098736 Steuer Nummer: 99024/23870 EORI-Nr.: DE760116663350817 Volksbank Mittlerer Neckar IBAN: DE30 6129 0120 0618 5970 00 BIC (S.W.I.F.T.): GENODES1NUE Deutsche Bank Esslingen IBAN: DE02 6117 0076 0012 1400 00 BIC (S.W.I.F.T.): DEUTDESS611 1 / 1 Commerzbank Esslingen IBAN: DE72 6114 0071 0825 4500 00 BIC (S.W.I.F.T.): COBADEFF611 8 254 500 00.
