Molykote G-5008 Dielectric Grease is a silicone grease containing a specially formulated base oil and solid lubricants. It has an NLGI 2-3 grade. It has excellent dielectric properties that
are maintained when the material is exposed to temperatures above 200°C (392°F) for extended periods. It also inhibits bonding of rubber to ceramic.


Molykote G-5008 Dielectric Grease is designed primarily for rubber/ceramic and rubber/rubber applications such as automotive spark plug boots and electrical connectors.

It is used in friction

  • Gaskets
  • Electrical contacts


  • Termal (heat) resistance
  • Working capacity in dust
  • High dielectric strength
  • Compatible with many plastics
  • Compatible with many elastomers
  • Avoidance of stick-slip

Problems to be Solved material

  • Stick-slip motion
  • Dust intrusion into lubricating points and abrasive wear
  • Electrical breakdown
  • Frequent re-lubrication
  • Plastic and elastomer details deformation and destruction

The combination of materials friction pair

  • Metal - Plastic
  • Metal - Elastomer
  • Plastic - Plastic
  • Plastic - Elastomer
  • Elastomer - Ceramic
  • Elastomer - Elastomer
