  • PROCESS FOR DRYING A NATURAL RUBBER
    Publication number: 20200317823
    Abstract: A process for drying a natural rubber starting from a wet natural rubber coagulum is provided. In a first step, the wet natural rubber coagulum is compressed at a temperature ranging from 185° C. to 210° C., then in a second step subjected to a flash adiabatic expansion at a differential pressure of at least 100 bar. Optionally supplemented by convective drying or by repeating the first and second steps, the process leads to a dry natural rubber having a nitrogen content of at most 0.3%.
