Lubricants
As sustainability is becoming more important throughout our global industries, biolubricants are becoming increasingly sought-after and refined, as they are biodegradable and are mainly produced from renewable raw materials.
The lubricant industry has long been a primary area of focus for the Peter Greven Group, and as our products have been based on renewable raw materials from the beginning, we are well positioned to offer sustainable lubricant products. To meet the growing industry requirements, we offer esters with certifications and listings tailored to the lubricant industry, including RSPO certified and NSF certified esters.
Our portfolio of LIGALUB® - Sustainable Ester Lubricants was especially developed for the lubricant industry. It includes high-quality synthetic esters that can be used as base oils:
- mono esters
- glycerol esters
- polyol esters
- complex esters
In addition to the ester product portfolio, we offer high quality metallic stearates and fatty acids. They are used as additives in the different lubricant systems.
Our brands
LIGALUB®, LIGASTAR®, COAD and LIGACID®
Applications
The lubricant industry offers various application areas which results in highly variable requirements for the esters. This makes a comprehensive, case-specific examination of the respective lubricant and its application requirements necessary in order to find the perfect ester.
Greases
Greases are solid or semi-solid lubricants. They consist of two components: a thickener system that generates the specific consistency of the grease, and a liquid lubricant providing the actual lubrication. The thickener system acts like a sponge that releases the liquid component under load in order to secure the essential lubricating effect.
Metallic stearates in the LIGASTAR® and COAD product range can act as thickeners for greases. Lithium, calcium, and aluminium stearates are the preferred products. Our LIGALUB® esters can be used as liquid lubricant components, with polyol and complex esters being favored - both in saturated and unsaturated variants.
Hydraulic Oils
Hydraulic oils are liquid lubricants for hydraulic systems and are needed to transmit energy – mainly volume flow or pressure – within those systems. Aside from their lubricating effect, they provide cooling properties and prevent corrosion, wear, and deposits.
The esters of our LIGALUB®product range are perfectly suited as base oils for hydraulic oils.
Saturated polyol esters or saturated complex esters are often the products of choice.
Industrial Oils
There is a wide range of types of gear boxes which, despite many differences and peculiarities, have one major thing in common: Gear oils are needed for the lubrication of spaces between the gear wheels and components.
Gear oil's main function is to reduce friction in order to avoid wear of the components. Additionally, it prevents corrosion and offers a cooling effect as the friction-related heat is taken away by the gear oil. Our LIGALUB®esters are used as base oils for this application. Saturated polyol and complex esters are the preferred ones, but unsaturated variants are also utilized in some cases.
Chains are used for a variety of applications. In general, they are responsible for the power transmission within the respective system. Lubrication of the chain is essential to secure the agility of the chain links and to minimize wear. The LIGALUB® product portfolio can also be used as a base oil for chain oils. As with gear oils, saturated polyol esters and saturated complex esters can be recommended.
Metal working fluids
Metal working fluids are often referred to as cooling lubricants. The essential functions of metal working fluids are to cool the tool and the material, and to reduce the friction between the components in order to prevent wear of the tool.
They can be categorized into two groups:
Water-miscible cooling lubricants are divided in emulsions and dissolutions. The physical characteristics of both categories are largely the same and they usually consist of more than 90% water. They are used in particular when good cooling rather than good lubricating effect is needed for grinding, sawing, or turning. In addition, water-miscible metal working fluids ensure good rinsing of the contact surfaces as the metal chips are removed by the fluid.
Cooling lubricant emulsions are widely used in the industry due to their strong cooling effect combined with relatively low cost. Water soluble metal working fluids are, in comparison to emulsifiable products, characterized by easier handling.
Our LIGALUB® polyol esters are particularly suitable as base oils for cooling lubricant emulsions, with unsaturated variants preferably used, while glycerol and polyethylene glycol (partial) esters are used for water soluble metal working fluids. High viscosity complex esters can be used as additives. For this purpose, unsaturated esters are preferred.
Compared to the water-miscible metal working fluids, the non-water-miscible fluids are characterized by their excellent lubricating effect, high pressure absorption capacity, and good protection against corrosion. They are also almost sterile and resistant to bacteria. This means that no biocides are needed to combat bacteria and fungi, which increases the longevity of the cooling lubricant.
Our saturated mono and polyol esters have proven to be excellent base oils for the production of non-water-miscible metal working fluids.
Engine Oils
Engine oils are essential for all kinds of engines in order to reduce mechanical and corrosion-related wear. The temperatures within an engine can be very high so it is important for the engine oil to show low evaporation loss.
LIGALUB® esters are mainly used as additives for engine oils to improve the evaporation loss of the mainly mineral based lubricants.
Our unsaturated complex esters are particularly effective with regard to the prevailing industry requirements.
Special Applications
In addition to the above-mentioned application areas, there are many more uses for our ester product range. Our deep rooted experience and technical know-how enable us to be your qualified partner for special applications to find the right ester for your requirements.
