UCON™ LB-650-X

ISO 680 polypropylene glycol fluid designed for high temperature applications.
Product Overview
UCON™ LB-650-X is a high performing lubricant technology from an alcohol-started base stocks featuring oxypropylene groups (m=0) with one terminal hydroxyl group. The UCON™ LB-650-X is water insoluble and has a viscosity of 650 cSt @ 100 °F. UCON™ LB-650-X is particularly well suited for applications requiring high thermal stability without risk of quickly degrading in hot environments.
