The Castrol Performance Bio HE range (previously named Carelube SES) are highly biodegradable hydraulic fluids, based on saturated synthetic esters. The range contains selected additives ensuring good oxidation stability, good anti-corrosion and anti-wear properties, as well as compatibility with bearing alloys containing lead. The synthetic base oil ensures Performance Bio HE has a very high viscosity index and an extremely low pour point.
Advantages
- High biodegradability
- Good oxidation- and hydrolytic stability
- Can tolerate low levels of mineral oil contamination and still maintain acceptable anti-foam performance
- High shear stability
