[0002] Natural rubber can be divided into two categories according to its form: solid natural rubber (sheet and granular rubber) and concentrated latex. In daily use, solid natural rubber accounts for the vast majority of the proportion, and granular rubber (i.e. standard rubber) is graded according to internationally unified physical and chemical properties and indicators. These physical and chemical properties include seven items: impurity content, initial plasticity, plasticity retention rate, nitrogen content, volatile matter content, ash content and color index. Among them, impurity content is the dominant indicator, and it is divided into five levels of 5L, 5, 10, 20 and 50 according to the amount of impurities.
