Rubber can mainly divided into natural rubber and synthetic rubber. Natural rubber comes from the rubber tree. After the solidify, dry and other processes, it becomes a solid with elasticity. While synthetic rubber is a man-made compound with high elasticity. In a broad sense, it’s a rubber made with chemical methods.
Natural rubber comes from rubber tree, which is plant in over 40 countries. However, the 9 main production countries are in Asia, such as Indonesia, Thailand and Malaysia. The amount of the 9 biggest production is 90% of the total in the world.
Natural rubber is an important strategic material. It’s widely used in transport, medicine, agriculture, national defense and many other industries. 70% of the natural rubber use for tire, 10% for rubber hose, 10% for shoot and 10% for others. While 80% of the rubber in tire industry is No.20 rubber.
What is No.20 rubber?
Shanghai Futures Exchange listed natural rubber futures in 1993. On Aug.12th, 2019 Shanghai International Energy Exchange listed a new future – No.20 rubber. Then what’s the differences between them?
Material
The natural rubber is fresh latex and the content of impurity is very low. But the No.20 rubber mainly absorbs smoked rubber sheet as the raw material. Because of the different raw material, the difference between them is mainly in the pretreatment.
