HIDROL BIO STER5 ISO 68

HIDROL BIO STER5 ISO 68 is a biodegradable HEES hydraulic fluid based on synthetic ester, for systems operating in environmentally sensitive environments. Its ISO VG 68 viscosity, higher viscosity, for systems with higher loads or elevated working temperatures, guarantees maximum performance with minimum environmental impact.

Formulated with a low acidity trimethylolpropane trioleate synthetic ester, it offers excellent performance in hydraulic systems operating in environmentally sensitive environments, with an operating range from –25 ºC to +120 ºC. It provides stable lubrication, high anti-wear protection, corrosion resistance, and great shear stability. Its high biodegradability (>60% in 28 days, WGK-1 classification) makes it ideal where there is a risk of spillage; its excellent filterability and compatibility allow, in most cases, direct use in systems designed for mineral oils without modifications.
