Performance LubricantsHigh Performance Lubricants for Electrical Connectorsfor Hybrid and Battery Electric Vehicles

Product Information
As the automotive market moves towards electrification
many designers are discovering the value of Krytox™ highperformance synthetic lubricants from Chemours. To meetthe needs of the emerging electric vehicle connector
application, Krytox™ lubricants can reduce friction, resist
water, and are dielectric (insulating). These attributes canhelp maintain the high performance of your electric vehicle
charging system.
Description
Krytox perfluoropolyether (PFPE) oils without additives
are good insulators. The typical dielectric properties areshown in the table. There is no difference in the electricalproperties of different grades of oils, as their chemical
properties are identical, and the primary difference isviscosity.

Design Advantages with Krytox™ Lubricants• Non-volatile• Nonflammable• Non-migrating

ASTM D1264 Water• No varnish

Temp °C% Loss

790.28• Nonconductive• No water washout– ASTM D1264 measures grease lost in a rotating
bearing where a water stream impinges on thelubricated areas. The unique chemistry of Krytox™
makes for a product that is not soluble in water ordisplaced easily by it.
• High temperature stability• Indefinite shelf life
• Chemically inert and non-reactive– Does not harm vulnerable amorphous thermoplastics– Does not harm EPDM-based elastomers– Usable with most metals up to 288 °C (550 °F)

Applications
Krytox™ lubricants can be used to reduce friction forassembly and sealing purposes• O-rings• Interconnect springs• Seals• Screw point• Latches

Friction Reduction• PFPE based lubricants reduces friction significantly at
all speeds and forces

Several grades of Krytox™ oil and grease are suitable forassembly/sealing aids, depending on the application type
and temperature range encountered (see table below).

• Pure PTFE is only efficient at low speed and low force
