METHOD FOR CONTROLLING VULCANIZATION RATE OF NATURAL RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling the vulcanization rate of natural rubber to give a natural rubber having a desired vulcanization rate. SOLUTION: The method for controlling the vulcanization rate of natural rubber comprises the control of the amount of serum of latex in the natural rubber before drying. Preferably, the method contains a step to add a viscosity stabilizing agent and preferably further a step to dry the rubber with a drum drier or a conveyor drier after the addition of the viscosity stabilizing agent.
