SYNTHETIC GREASES

Synthetic greases are lubricants able to cover applications with temperatures, exercise conditions and durability that go ahead limits of mineral greases. Synthetic fluids, differently from minerals that originate from processes of petroleum refining, are obtained, through specific processes of synthesis. Are part of this range PAO (polyalphaolefin), esters or diesters with optimum polarity on surfacesPAG that assures reduces residues and compatibility with some particular elastomer (EPDM), silicone with optimum gliding properties and fluorinated for applications in extreme conditions.

ASSETS OF SYNTHETIC LUBRICANTS

Synthetic lubricants are obtained through chemicals reactions in which pressure, temperature and components ratio are carefully checked; in this way is obtained a pure product with a molecular dimensions distribution extremely narrow and uniform.

This characteristic implies that synthetic lubricants gives advantages compared to mineral lubricants; those advantages can be obtained in 6 points:

  1. Solidification temperature clearly lower: a mineral lubricant of medium viscosity solidifies to -10°C, a synthetic lubricant can reach -80°C.
  2. Low volatility: a synthetic lubricants evaporates until 10 times lower than a mineral lubricant.
  3. Greater resistance to oxidation from oxygen: a synthetic lubricant can decompose with oxygen until 3 times lower than a mineral oil with same additives.
  4. Great resistance of lubrication film: a synthetic lubricant creates a lubricant film more strong than a mineral lubricant: advantages are the greater resistance to loads and the friction coefficient reduction.
  5. Lower carbon residue: a synthetic lubricant can produce carbon residues if expose to very high temperature, until 10 times lower than a mineral lubricant.
  6. More compatibility with rubbers and plastics: thanks to a wide choise from chemical point of view, synthetical lubricant give best guarantees of compatibility with plastics and rubbers material respect to mineral lubricants

Depending on the chemical nature of raws materials used for synthetic lubricants production, can be obtain different types:

  • PFPE (Fluorinated): lower friction coefficient, wide thermal range, very high resistance to chemical agents, resistant to higher temperature and non-flammables.
  • PAG (polyalkyleneglycol): lower friction coefficient, low residues and high ability to remove heat; compatibles only with some types of plastic materials and seals.
  • Ester: usefull for high temperatures, lower friction coefficient and low volatility; used in biodegradables lubricants production.
  • PIB (Polyisobutenes): call also polymers and used for increase lubricants viscosity and adhesivity .
  • Silicones: lower lubricant power, great stability for viscosity and temperature, wide thermal range and great resistance to chemicals agents.
  • PAO (Polyalphaolefine): are the most common and guarantees a wide range of temperature, good lubrication and compatibility with most of materials.

Regulations always more restrictives, in purely performance terms but also in environmental terms, are clearly contributing to an increase in demand of synthetic  respect to mineral lubricants .
