Abstract
This review referred to production, mastication and compounding of natural rubber. Natural rubber is made from fresh latex or spontaneous coagulum of latex. The production methods and grades of them were explained. The effects of temperature and time on mastication were discussed, and it was suggested that not only control of temperature and time but also raw rubber conditioning were important to get constant plasticity of compounded stocks. The role of inorganic fillers on physical properties of vulcanizates were emphasized.
