As lubricating greases For machines are fundamental in industrial applications, especially when oils do not offer proper performance. To norm ASTM D288 defines them as solid products to semi -pans, obtained from a thickening agent in a lubricating liquid. In some cases, other ingredients are added to offer specific properties.
Another common definition describes the grease as a semi -solid combination of petroleum derivatives with metal soaps or mixtures of soap, suitable for different types of lubrication.
The term “grease” comes from Latin crassus, which means fat. This origin reflects its main feature: firm consistency and ability to form protective barriers.
Where greases are more efficient
Greases are used at points where lubricating oils do not work well, Due to its tendency to drain. Additionally, offer the advantage of forming a protective seal, that prevents contaminants such as dust and moisture, prolonging component life - for example, in bearings.
Historically, The first types of greases emerged from mineral oils thickened with calcium soaps. At the moment, Technology has evolved into the most effective formulas, based on calcium complexes e Lithium Complexes, that offer better resistance and performance under different operating conditions.
Essential raw materials for greases
Barentz maintains local inventory and offers a wide variety of raw materials for formulators and grease producers, including:
- Hydrogenated Castor Great Acid (12-HSA)
- lithium hydroxide
- Molybdenum disulfide
- Polyalphaolefins
- Antioxidants (BHT, aminicos, etc.)
- Anticorrosive additives (Clinua NA-SULL In Industry – USA)
- Sebácic acid (Decanodiological acid)
- Pusta (dodecanodiological acid)
These inputs make it possible to develop high performance greases, capable of meeting demands from different industrial segments with reliability, Protection and Efficiency.
