Dielectric Greases
PolySi® G-MAN® Lubricants

Eliminate Your Arcing IssuesPolySi Dielectric Grease Tubes

PolySi® G-MAN® Silicone Dielectric Greases and Non-Silicone Dielectric Greases are considered electronically neutral. These materials neither hinder nor promote the electrical performance of an existing system. The real goal for grease in an electrical interface is the ability to control two variables: fretting and corrosion. Fretting and corrosion cause more damage to stationary interfaces than any other failure mode. For this reason, lubrication of the interface is needed to prevent the corrosion caused by oxygen and mitigate the fretting and micro-movement in electrical connections. If metals are mated for an electrical application, grease will make the connection last. PolySi® Technologies offers silicone and non-silicone dielectric greases.
