LUBIMAX® 141, it is a viscosity index improver (VII) used in lubricant formulations. It is an ethylene/alpha-olefin copolymer (OCP) supplied in pellet form.
Key specifications reported for LUBIMAX 141 include:
Ethylene content: ~73%
Density: ~860 kg/m³
SSI: ~37
Pour point: about −15°C
Form: pellets/granules
Typical use: engine oils and other lubricating oils
Function: increases viscosity and helps maintain viscosity over changing temperatures.
LUBIMAX 141 is primarily used as a Viscosity Index Improver (VII) in lubricating oils.
Main functions of LUBIMAX 141
-
Improves viscosity index (VI)
Helps the oil maintain a more stable viscosity as temperature changes. -
Thickens the base oil at high temperature
The polymer expands as temperature increases, helping prevent the oil from becoming too thin. -
Improves high-temperature lubrication
Helps maintain an adequate lubricating film when the engine or machinery is hot. -
Provides multigrade performance
It is used to formulate oils such as SAE 10W-40, 15W-40, 20W-50, etc. -
Controls viscosity change with temperature
Without a VII, an oil that is sufficiently thick when cold can become excessively thin when hot.
In simple terms:
LUBIMAX 141 = polymeric viscosity modifier that helps lubricating oil stay thick enough at high temperatures while allowing suitable low-temperature viscosity.
