  • Lower flammability than mineral oils;
  • Extended change intervals;
  • Excellent anti-wear and anti-corrosion performance
  • Good filter ability;
  • Non-toxic, high level of biodegradability;
  • Long service life, lower maintenance costs.

Application area:

  • Recommended for all hydraulic systems, operating in conditions where the use of a mineral oil would present a fire hazard. Typical uses include: steel mill equipment, casting shop machinery, furnace door closers, die casting machines and underground equipment,etc.
    Applied temperature range: -50ºC~60ºC , applied pressure: 20MPa.
