Industrial grease components
Industrial lubricant solutions for terephthalamate and polyurea greases
For industrial greases, Clariant offers a broad range of specialty ingredients. Among others, thickener for terephthalamate greases, precursors for polyurea greases, a range of polyalkylene glycols for ISO VG classes from 32-1000 and more various additives are provided. Within its grease components, Clariant provides both soap and non-soap based thickeners for greases. Greases can be more than lubricants, they are often also used as sealants, corrosion inhibitors, shock absorbers and noise suppressants.
By varying factors like starting alcohol, amounts of ethylene and propylene oxide as well as catalysts used, PAG base oils can be precisely tailored to various requirements, such as:
- Viscosity,
- Polarity and water solubility,
- Freezing point
- Thermal properties,
- Lubrication,
- Hydrodynamic friction
Clariant’s Greases components are biodegradable and sustainable solutions that can improve your carbon footprint, due to bio-based raw materials. Many of Polyglykol products are registered on the LuSC list and comply with the updated 2020 criteria for sustainability requiring EU Ecolabel certifications for lubricants.
