CARTER BIO has very good extreme pressure properties and a high scuffing load capacity ensuring good protection of gears operating under high load. The synthetic base oils used combine good lubrication properties and a high oxidation stability.These base oils are fulfilling the European Ecolabel criterias for the Biodegradability, the Renewable carbon content and for the Ecotoxicity. The Biodegradability of CARTER BIO is over 60% after 28 days (OECD 301B testing procedure). CARTER BIO provides lubrication advantages at both high and low temperatures compared to mineral oils. - The very high viscosity index and shear stability of CARTER BIO ensures a high lubricating film thickness at high temperatures (see table page 2). - The lower pour point and the low temperature viscosity will ensure a better start up in cold operating environments. CARTER BIO is ensuring a high corrosion protection , confirmed with sea water contamination.
