This course will discuss polyalkylene glycol (PAG) technology including their chemistry, manufacture, key performance properties and challenges. It will also focus on the wide range of applications where PAGs are used today. Furthermore the presentation will highlight how innovation is leading to new PAG technologies such as the recent introduction of Oil Soluble PAGs - a new type of Group V base oil and performance enhancing additive. The presentation will discuss how PAGs are finding use in new applications to solve some of today's modern day tribology challenges.
