Synthetic oil/grease

    Range of synthetic greases, for temperature or length-of-service constraints that conventional greases cannot satisfy.

Synthetic greases are composed of more than 80% synthetic base oil which provides the lubrication.

Under extreme service conditions (very low temperatures of the order of -40°C or very high > 300°C), the use of synthetic base oils is necessary to reach performance levels that traditional greases based on mineral oils cannot attain. The synthetic base oils used are in particular:

  • PAO (PolyAlphaOlefin)
  • PIB (PolyIsoButene)
  • PAG (PolyAlkyleneGlycol)
  • PFPE (PerFluoroPolyEther)
  • PTFE (PolyTetraFluoroEthylene)
  • Silicones
  • Synthetic esters
  • These base oils are very resistant to oxidation and are notably used for lifetime greasing at standard temperatures. Synthetic greases represent a good number of speciality greases and are very often chosen for alternative maintenance solutions.

Applications

  • Bearings for electric motors
  • Micro-mechanisms, robots
  • Micro-electronic parts, connectors
  • Protection of glueing tables
  • Grooves and lips of sealing gaskets
  • Slides, rails
  • Cylindrical, conical roller bearings
  • Furnace rollers
  • Motor vehicle interiors

Characteristics

  • The thickener is determined by the service constraints excluding temperature: Lithium or Lithium Calcium, Lithium complex, Calcium Sulphonate, Polyurea, Bentone™, Polyamide, PTFE or fumed silica, all thickeners can be envisaged
  • Additives (liquid or solid) allow the specificity of the grease to be further refined
  • The base oil will express the choice of formulation to respond to the lubrication issue

The range of synthetic greases has the following characteristics:

  • very low pour point for operation at low temperature
  • exceptional resistance to oxidation for a very long lifetime
  • very high thermal stability avoiding decomposition at high temperatures
  • High viscosity index (VI) to maintain suitable viscosity whatever the temperature
  • good lubricating performance with or without additives

All these greases can be offered in grades NLGI 000 to NLGI 3. They all show very good stability with respect to oxidation and can be used over a wide range of temperatures.

Product benefits

Because of their technical qualities, synthetic greases are the obvious choice for certain applications. They can also be an alternative for optimising and spacing out your maintenance operations.

Characteristics Customer benefits
Stability to oxidation and appropriate viscosity index
Lifetime and protection of elements = Reduction in maintenance costs
Wide range of service temperatures, specific levels of performance
Lubrication bringing a technical solution => avoid special equipment or costly modifications = Profitability
Limited evaporation , low friction coefficient
Reduced grease consumption => less processing of packaging, water = reduction in overall lubricant costs and preservation of the environment

      The use of synthetic greases systematically leads to a very important saving in labour, machine stoppages and above all rejection of manufactured parts.
