Are you a gear oil formualator, looking for base oils to help meet new e-fluid needs? Our synthetic polyglycol base oils are ideally suited for use in EV fluids.
- Outstanding thermal properties (heat capacity and thermal conductivity)
- Outstanding low friction coefficient
- Hazard label free, readily biodegradable
- Good viscosity-temperature behaviour
Geared to purpose: Polyglycol base oils tailored for testing
Polyglycol (also known as PAG) base oils are available in a wide range of viscosity grades and can be matched with different additive packages to allow them to be precisely tailored to the evolving needs of EV drive fluids. To explore the capabilities of PAG base oils in terms of properties that are relevant to e-mobility, Clariant synthesized a small series of polyglycols with different chemical structures and properties, and subjected them to a series of tests.
The tests showed that Clariant’s synthetic PAG base oils (notably Polyglycol E04 E and Polyglycol E03 A) largely outperformed a polyalphaolefin (PAO) benchmark with respect to key parameters such as energy efficiency, friction coefficient, heat transfer, and ecotoxicity/sustainability.
Time to change gear and steer for clear benefits
Clariant’s polyglycol base oils offer an array of beneficial capabilities that make them ideally suited for use in EV fluids such as reduction gear oil. The tests carried out by the company provide a strong evidence base for their performance characteristics.
The current relatively flexible situation regarding OEM standards and gear design offers scope for innovation in EV drive fluids. Ultimately, only highly efficient EV drivetrains supported by high-performance lubricants are capable of delivering the longer ranges that customers want and that EV manufacturers need in order to position their products in the market.
The race for electric mobility has only started. Don‘t miss out on it! The current challenges in energy efficiency and thermal management offers scope for innovation in EV drive fluids. Clariant is currently looking for partners to continue the development of innovative lubricants containing PAG base oils and bring new solutions to the market that would make electric mobility more efficient. Join us in our efforts to shape the future of electric mobility and speciality lubricants.
