CONDUCTIVE SILICONE + EPDM SI


                                                               GT 5068






             UNIQUE SOLUTION                          GT 5068 was developed by combining a conductive silicone filled with
                                                       silver-plated aluminum (GT5000) with a doped EPDM silicone 65 shore.
                                                         This mixture is intended to meet the constraints of a corrosive
                                                          environment by separating the shielding function and the
                                                            sealing function to respond to specific applications.



     •   Reach and RoHs compliant
     •   Good resistance to abrasion
     •   Resistance to hydraulic fluids like
         phosphoric Ester (Skydrol)
     •   Low permeability to water vapour and other
         gases
