Electrically Conductive Greases
Lithium-soap and silica-based electrically conductive greases,
including specially low-carbon greases for superior channeling
ability...
If static discharge poses a hazard to your application, consider
a conductive lubricant by Nye.
Conductive
grease typically serves as a ground. For example, it is applied
to ball bearings in computer equipment where it allows static
discharge to pass through the bearing instead of building up,
arcing, and pitting the rolling element or fluting the raceway -
accelerating wear. It serves a similar purpose in treadmills,
where the rubber belt can generate static electricity which
makes its way to the bearing. A conductive grease is also used
to bleed static away from the toner cartridge toward the shell
in laser printers and office copiers. A custom-formulated,
fluorinated conductive grease was recently developed by Nye for
automotive battery lugs, to enhance conductivity over a wide
temperature range. Note: Never use conductive grease on sliding
switches, which could malfunction if a conductive grease is
applied to the contacts.
Volume resistivity of
Nyogel 758G is approximately 300 ohm-cm. Nyogel 753G and Nyogel
756G are gels not pastes. They rely on a proprietary carbon
filler, rather than traditional metallic particles, for their
conductivity. Nyogel 758G is an excellent channeling bearing
grease. It relies primarily on a synergistic effect among its
additives, not carbon or metallic filler, to create an electron
pathway through the grease.
