Oil-soluble polyalkylene glycols (PAGs) are versatile additives for mineral oil and PAO-based lubricants

Conventional polyalkylene glycols are not miscible with hydrocarbons like mineral oil or polyalphaolefins (PAO), which are the common choice of basis oils in the production of lubricants. The new OSP product line has been developed to offer broad solubility behaviour that will facilitate the formulation of non-polar lubricants as well as improve their performance. OSPs are explicitly not designed as alternative basis oils, but rather to offer the following advantages and properties in the dosing of additives:

  • Excellent lubrication
    • Improved wear protection
    • High polarity and thus strong affinity to metal surfaces
    • Intact film of lubricant under high temperatures and loads
  • Large viscosity range
    • Viscosities ranging from 10 to 66,000 mm/s2
    • High inherent viscosity index (VI)
    • Very low pour point (-30 to -50 °C)
  • Outstanding stability
    • Excellent thermal resistance
    • High flashpoint
    • Hydrolytic stability

Typical applications include:

  • Automotive: engine and transmission oil
  • Industrial applications: hydraulic and metalworking fluids as well as lubricants for compressors
  • Greases

  

Test series

Residue reduction with PAG technology

The Panel Coker test measures the tendency of an oil to coke on a heated metal surface. The oil is dropped onto a hot surface over a defined period of time and evaluated by the residues it forms. A comparison was made between mineral oil, PAO, and water- and oil-soluble PAGs.
