Abstract

Measurements made of water lubricated friction of vulcanised rubber sliding against glass and against itself show that the level of friction is sensitive to the acidity/alkalinity of the water. The friction of natural rubber was markedly less at pH values greater than nine. The effect is believed to be due to the presence of the non-rubbers in natural rubber; evidence points to the fatty acids as being the active component. The effect is not observed for synthetic polyisoprene. The results have a bearing upon the action of water lubricated rubber articles.
