Abstract

The rubber products are made by mixing finely divided rubber scrap with rubber latex, together with vulcanising agents and coagulation retarders for a few minutes, transferring to a mould and pressing to cause at least partial coagulation, drying, and opt. pressing again. In this way non porous or slightly porous products are obtained without intensive mixers or calenders.
