DEVELOPMENT OF SELF-LUBRICATING AND NON-ADHERING ELASTOMERIC MATERIALS

Abstract

In the development of self-lubricating and non-adhering elastomeric materials, the main property investigated was the surface friction properties of rubber compounds with the object of developing compounds with low starting coefficient of friction values. A simple test apparatus and procedures which measured quantitatively the starting coefficient of friction was developed. The lowest starting coefficient of friction values were obtained by modifying a nitrile rubber elastomeric base compound with a fluorocarbon fabric laminate or fluorocarbon chemical treatment of the surface. Polysulfide fluorocarbon and silicone rubbers had low SCf values which did not approach those obtained with fluorocarbon films on elastomeric bases. Experiments were designed to investigate the mechanism seizure of rubber compounds with metal parts during sustained periods of idleness. Apparently the so-called seizure phenomena is induced by increased humidity and temperature conditions.
