PFASs are used in lubricant components across a range of industrial sectors including transport, defence, energy and electronics, and in production industries such as oil and gas, iron and steel, chemical and others. PFASs in lubricants impart wide and unique combinations of properties that in turn enable a range of technical functions simultaneously. These are associated with key performance qualities often necessary to withstand ‘harsh’ or ‘extreme’ conditions and where the use is considered to be ‘critical’. Use in hydraulic oils is specific to corrosion inhibition.
Progress in substituting PFASs in lubricants has been limited. Due to the technical and economic challenges involved in developing suitable alternatives—and in the absence of strong market drivers—the market for PFAS-based lubricants is expected to continue expanding. The report includes specific policy recommendations to address the barriers and challenges associated with the substitution of PFASs in lubricants and hydraulic oils.
