A grease is a stable mixture of a base oil and a thickening agent. KEMAT Polybutenes, Polybut™ and Polybol™ all have particular properties as base oils as well as modifiers to achieve the level of modern properties for Polybutene greases.
|Pour Point||Improved performance over mineral oils under low temperature conditions||Low temperature greases for automotive and industrial use|
|Toxicity||No detectable aromatic content and practically non-toxic||Incidental food contact greases|
|Colour||White or transparent when thickened with light-coloured thickening agent||Food or medical greases|
|Water resistance||Hydrophobic with good sealant properties for corrosion protection||Greases for bottling and canning lines|
|Inertness||Good chemical and physical stability; permanently non-drying||Corrosion protection; wire rope lubricants; cable greases|
|Viscosity||Wide range to modify adhesiveness and temperature response of grease||Heavy-duty gear operated over wide temperature range|
|Volatility||Depolymerizes to volatile compounds above 250°C without residue or staining||Graphite or molybdenum disulphide suspensions|
End User Applications
KEMAT Polybutenes of low viscosity Polybut™ can be used as the base oil for the manufacturing of a grease.
KEMAT Polybutenes of medium to high viscosity Polybol™ are used in conjunction with a conventional mineral oil to produce a blend oil from which a grease can be manufactured. The polybutene will adjust the viscosity and Viscosity Index (VI) of the mineral oil to modify and improve the properties of the finished grease.
