Electronic Connector Contact Lubricants: the Polyether Fluids Sliding Studies of New Connector Contact Lubricants

The results of a search for connector contact lubricants which have higher service temperatures than a widely used five-ring polyphenylether (5-PPE) fluid are reported in a companion paper and continued here. Comprehensive studies of the mechanisms of lubricant depletion and their applicability to fluid coatings were made. They show that the maximum service temperature to which contacts with a coating from a 0.5-wt% solution of the 5-PPE in a volatile solvent, such as 1,1,1-trichloroethane, may be continuously subjected is about 30-50C assuming a product life of 20 years.
