Advanced Fire Resistant (HFDU) Synthetic PAG Hydraulic Oil. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 is a synthetic fire-resistant hydraulic fluid, based on very high VI, polyalkylene glycol (PAG) base stocks, coupled with a proven ashless additive package. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 has been designed to minimize fluid degradation and thus extend fluid changeout intervals under even the most severe operating conditions. Shell Fire-Resistant Hydraulic Fluid S3 DU 46 provides the performance properties demanded by today’s high-performance hydraulic systems. At least 97% by mass of this lubricant's components are readily biodegradable, achieving a passing result of ≥60% according to OECD 301B.
OECD 301B biodegradability above 60 %
A test result rather than a norm: OECD 301B measures the carbon dioxide evolved over 28 days. Above 60 % counts as "readily biodegradable", the threshold the environmental labels require.
