03

Processing and use

Processing

  • Viscosity, vapour pressure, oxidation, contamination and additive depletion must be evaluated at service temperature.

Applications

  • Coolants and heat-transfer loops
  • Hydraulic or lubrication systems
  • Process equipment

Selection considerations

  • Use a current product datasheet for viscosity index, fire point, seal compatibility and approvals.

Sources and context

Sources

Confirm the applicable specification, product form and condition before using values for design or procurement.

Supply and sustainability

Widely available, but additive packages and approvals are product specific.

Leak prevention, service life, reclaimability, toxicity and disposal route dominate environmental performance.

Strategic context

Critical to heat transfer, equipment reliability, energy efficiency and manufacturing stability.
