UCON™ LB-550-X

ISO 460/680 polypropylene glycol fluid designed for high temperature applications.
Product Overview
UCON™ LB-550-X is a high performance lubricant from an alcohol-started base stock featuring oxypropylene groups (m=0) with one terminal hydroxyl group. The UCON™ LB-550-X is water insoluble and has a viscosity of 550 cSt @ 100 °F. UCON™ LB-550-X is particularly well suited for high temperature operation where traditional lubricants are prone to degrade & fail.
