PAO 4

About this item

PAO 4 is a low viscosity poly alpha olefin fluid that can be used as a base stock for a wide range of engine and industrial lubricating oil products. It is manufactured by the polymerization of alphaolefins. PAO 4 has optimal combination of volatility and low-temperature fluidity. It provides high lubrication properties and increased film thickness at high temperatures. It also has excellent oxidation resistance, shear stability and a high flash point and is completely compatible with a wide range of synthetic and mineral base oils.

 

APPLICATION

PAO 4 can be used as a base stock for a wide range of engine and industrial lubricating oil products, both mineral oil and synthetic based. Some examples:

  • Passenger car engines
  • Commercial heavy-duty diesel engines
  • Gear Oils
  • Compressor Oils
  • Turbine Oils
  • Circulating Oils
  • Grease

HANDLINGINFORMATION

PAO 4 is a viscous liquid polymer and is normally handled at slightly elevated temperatures. For general purposes, the following maximum storage and handling temperatures are recommended:

  • Storage 50°C (122°F)
  • Handling under Nitrogen 100°C (212°F)
  • Handling without Nitrogen 80°C (176°F)

 

SAFETYINFORMATION

PAO 4 exhibits an extremely low level of dermal, oral and inhalation toxicity, as well as, low eye irritation.

 

SHIPPINGINFORMATION

Product is shipped under a nitrogen blank in tank trucks, railcars, and non-returnable 55-gallon (imperial) steel drums (370 lbs. net).
