    Abstract: In prior art, the wear resistance and frictional properties of a sliding member are improved by adding bismuth, an alkaline earth metal salt or the like, but not lead, to a polytetrafluoroethylene used as a base resin, in view of the undesirable influences of lead on the environment. However, a further improved wear resistance at a high PV value has been desirable. In the present invention, a sliding member having excellent wear resistance and frictional properties even when used at a high PV value can be obtained by using a thermosetting resin as a base resin in a proportion of 50 to 80 vol % and adding thereto a PTFE with a molecular weight of 3,000,000 or more in a proportion of 10 to 40 vol % and bismuth and/or a bismuth alloy in a proportion of 1 to 20 vol %.

    Abstract: Extreme pressure lubricants, concentrates and greases. Disclosed herein are extreme pressure metal working lubricants which comprise a lubricant base material and a reaction product of (1) an amine containing from 1 to about 30 carbon atoms and (2) sulfamic acid or derivative thereof containing from 1 to about 30 carbon atoms. The reaction product or extreme pressure additive may be either water soluble or oil soluble. Amines containing from 1 to about 7 carbon atoms are generally used for making water soluble reaction products, and amines containing 8 or more (up to about 30) carbon atoms are generally used for making oil soluble reaction products. Water based lubricants comprise water and a water soluble reaction product. Oil based lubricants comprise an oil of lubricating viscosity and an oil soluble reaction product. Reaction products may be either addition products or sulfonamides.
