PAGs - Polyalkylene Glycols, used as the base fluid for synthetic gear and bearing lubricants and metal working fluids are designed to operate over a very wide range of temperatures and conditions. These fluids provide excellent anti-friction, anti-wear and high load-carrying properties - with inherently high viscosity index which reduces change in viscosity over increased temperatures.

A Series - Water Soluble PAGs with a 1:1 ratio of ethylene oxide and propylene oxide

These products find extensive application when manufacturing and formulating various water soluble products:

  • Gear and Calender Lubricants
  • Metal Working Formulations
  • Compressor Lubricantsdripping bearing.jpg

W Series - High viscosity co-polymers of 75% ethylene oxide and 25% propylene oxide giving water soluble products.

The high viscosity and low volatility of these products make them ideally suited neat for high temperature lubrication. Compared with mineral and most other synthetic oils, W series have very high hydrodynamic lubricity leading to low wear:

  • Hydraulic Fluids
  • Quenching Fluids
  • Metal Working Fluids
  • Textile Lubrication

P Series - Polyalkylene Glycol of mono initiated propylene oxide homo-polymers giving water in-soluble products used where a water free environment is required. 

These products find extensive application when manufacturing and formulating various water in-soluble products, for example:  

  • Gear and Calender Lubricants
  • Metal Working Formulations
  • Compressor Lubricants
  • Textile Lubricants

PRB Series - Reversed Block Copolymer Surfactants

Difunctional block copolymer surfactants with terminal secondary hydroxyl groups.

100% active nonionic surfactants:

  • Metal Working Fluid
  • Metal Cleaning Agent
  • Machine Dishwashing Agent
  • Detergents and Cleaners

Aqueous solutions of PAGs provide excellent lubricants and heat transfer agents for use in metal cutting and spinning processes. The fluid can be used alone or combined with other water soluble products, such as amine soaps, amides or phosphate esters. Many PAG fluids are less soluble in hot water than cold, and this property can be exploited to provide a most effective combined coolant and lubricant.

  • A Series - A50, A150, A225, A1000
  • W Series - W270, W18000, WB5540
  • P Series - P75, P125, P225, P335
  • PRB Series - PRB172, PRB174

 Textile Fibre Lubricants 

PAGs have proven application in almost every stage of textile fibre lubrication. Depending upon the application, fibre type and yarn structure, the desired level of friction control can be obtained by selecting one, or a combination of grades.

  • A Series - A50, A150, A225, A1000
  • W Series - W270, W18000

These fluids reduce the change in viscosity with increase in temperature under isothermal conditions:

  • Low friction losses leading to reduced sump temperatures, and higher gear efficiencies
  • High thermal stability, providing extended lubricant lifetime
  • Excellent load-carrying properties, reduced wear and extended equipment lifetime
  • Inherently high viscosity index giving wide temperature operation and faster warm-up



PAGs provide excellent Viscosity Index, often above 200. High viscosity index lubricants, such as PAGs, protect better in operations with temperature variations.


PAGs are superior to mineral or refined oils in reducing friction. The outstanding friction-reducing ability keeps wear rate low which helps extended equipment lifetime.

Pour Point

PAGs generally have low pour points, permitting some grades to be used down to -50°C. They are wax free and not affected by cooling to below their pour points.


PAGs have enhanced thermal and oxidative stability, which reduces the formation of sludge, corrosion, and deposits.


Separation is showed at higher temperatures for A and W series. This helps to explain their lubricity in water. PAGs are not soluble in mineral oils or hydrocarbon solvents.

Effect on metal

PAGs are non-corrosive to iron, steel, bronze or aluminium under normal conditions and can be used without restriction in industrial systems. Inhibitors can be included to control corrosion where water is present.

Effect on Rubber & Paints

PAGs have little or no effect on most natural and synthetic rubbers, compounds, seals or gaskets. However, their unusual solvency can affect some paints, and two pack epoxy and phenolic paints are generally required.
