Priolube™ esters

Priolube is our range of synthetic esters which offer exceptional in-use performance as well as possessing excellent environmental credentials. The brand name was adopted by Croda following the acquisition of the oleochemicals division of Uniqema in 2006.

Our Priolube range of esters comprises a huge portfolio of chemistries, which offers the formulator an unrivalled degree of formulation flexibility across a broad range of applications.

High performance esters with excellent environmental profiles

Globally, across many markets including automotive, industrial and marine, there is an increasing awareness of the environmental impact of lubricant formulations. Many regions have already restricted the use of mineral oil-based materials and place strict requirements around lubricant use.  

Priolube offers our customers the chance to navigate the dynamic regulatory landscape and protect our environment, whilst simultaneously maximizing product performance. Our expertise in ester technology, together with our application know-how, means that we are best placed to tackle the lubrication challenges of today and meet the challenges within the energy market in the future.
