Lubricants
PETER GREVEN – Your partner for ester lubricants
Sustainability is increasingly vital in the lubricant industry, leading to a growing emphasis on biolubricants. These environmentally friendly options are biodegradable and primarily derived from renewable feedstock, making them a crucial part of modern lubrication solutions.
Our LIGALUB® portfolio has been specifically developed for this sector, featuring high-quality sustainable esters suitable as base oils:
MONO ESTERS | GLYCEROL ESTERS | POLYOL ESTERS | COMPLEX ESTERS
We cover a viscosity range from 8 upt o 1,000 mm²/s at 40 °C and can offer LuSC listed and RSPO certified or NSF HX1 certified products.
Esters excelling in performance
Polyol and complex esters are the heart of our ester portfolio and one of our core competencies. To ensure distinguished performance, we conduct extensive laboratory testing on oxidation and hydrolysis stability, aging and low-temperature behavior, as well as demulsibility and evaporation loss.
Products beyond base oils
Even though esters are our main products for the lubricant industry, metal soaps and fatty acids are used as sustainable additives in specific lubricants.

Application areas
The lubricant industry encompasses a wide range of application areas, leading to highly variable requirements for esters. To identify the ideal ester for specific lubrication needs, a detailed and case-specific analysis of the lubricant and its application requirements is essential. Therefore, the following explanations serve as a general guideline rather than a definite solution.
Greases
Greases are essential solid or semi-solid lubricants widely used in various industries. They consist of two main components: a liquid lubricant providing effective lubrication and a thickener system giving the grease its specific consistency. The thickener system functions like a sponge, releasing the liquid lubricant under load to ensure optimal lubrication performance. This dual structure makes greases a reliable lubricant.
LIGALUB® esters serve as high-quality liquid lubricant components, particularly polyol and complex esters, available in both saturated and unsaturated variants. Additionally, our LIGASTAR® metal soaps are excellent thickeners for greases, with lithium, calcium and aluminium stearates being the preferred choices.
The primary function of gear oils is to reduce friction, thereby minimizing wear on components. Additionally, gear oils help prevent corrosion and provide a cooling effect by dissipating friction-related heat. Our LIGALUB® esters serve as excellent base oils for gear oil applications, with saturated polyol esters and saturated complex esters being the preferred choices. Unsaturated variants are also available for specific needs.
Chains are integral to many industrial applications, primarily responsible for power transmission. Effective chain lubrication is essential to maintain the agility of chain links and reduce wear. The LIGALUB® product portfolio offers suitable base oils for chain oils, where saturated polyol and complex esters are recommended for optimal performance.
Metal Working Fluids
Metal working fluids, commonly known as cooling lubricants, play an essential role in different manufacturing processes. Their primary functions include cooling tools and materials while reducing friction between components, thereby preventing tool wear.
There are two different types of metal working fluids:
Water-miscible cooling lubricants include emulsions and dissolutions, which typically contain over 90% water. They are especially effective when optimal cooling is required, such as during grinding, sawing, or turning operations. Water-miscible fluids also facilitate excellent rinsing of contact surfaces, effectively removing metal chips.
Being widely used across various industries, cooling lubricant emulsions offer a strong cooling effect at a relatively low cost. Compared to emulsifiable products, water-soluble metal working fluids are characterized by their ease of handling.
LIGALUB® polyol esters are ideal base oils for cooling lubricant emulsions, with unsaturated variants being the preferred choice. Additionally, glycerol and polyethylene glycol (partial) esters are recommended for water-soluble metal working fluids. High-viscosity complex esters can also be utilized as effective additives, with a preference for unsaturated esters.
In contrast to water-miscible options, non-water-miscible metal working fluids excel in their lubricating properties, high pressure absorption capacity, and corrosion resistance. These fluids are nearly sterile and resistant to bacteria, eliminating the need for biocides to control microbial growth and enhancing the longevity of cooling lubricants.
With regard to non-water-miscible metal working fluids, our saturated mono and polyol esters have proven to be excellent base oils.
Engine Oils
Engine oils play a vital role in maintaining the performance and longevity of all types of engines. They are designed to minimize corrosion and mechanical wear, ensuring smooth operation under high temperatures. One key feature of effective engine oils is their ability to exhibit low evaporation loss, which is crucial for the longeivity.
