Abstract

A method of softening natural rubber consists of disintegrating coagulum into granules or crumbs, treating where necessary with a complexing agent to remove harmful metals such as copper and manganese, and spraying with a solution or a water or oil dispersion of a peptizing agent and then drying at a temperature high enough to activate the peptizing agent. In a modification the peptizing agent may be added direct to the coagulum, as a dispersion in oil or as a rubber/oil/peptizing agent master-batch, during the preparation of crepe. In the latter case the agent is preferably added to the scrap washer or on the first roll of the crepeing battery. Specifications 531,723 and 964,562 are referred to.
