As we all know, rubber is made from raw rubber collected by manually cutting the bark on the rubber tree as raw material, but what kind of process has it gone through to become this soft and tough rubber? What varieties are there? Today, industrial-grade rubber suppliers will take you to understand the production process and the main varieties of rubber products. There are many types of rubber products, but the production process is basically the same. The basic process is six basic processes: plasticizing, mixing, calendering, pressing, forming, and vulcanization. Of course, basic processes such as raw material preparation, finished product sorting, inspection and packaging are also indispensable. The processing technology of rubber is mainly to solve the two contradictory processes of plasticity and elastic properties. Through various technological methods, the elastic rubber is transformed into a plasticized rubber, and then various compounding agents are added to make a semi-finished product, and then the semi-finished product with plastic is transformed into a rubber product with high elasticity and good physical and mechanical properties through vulcanization. In order to meet different usage requirements, different compounding agents and processes are adopted to make rubber products for various purposes.

1. Natural rubber NR
Introduction: Natural rubber NR is made from rubber tree latex and is a polymer of isoprene. It has good wear resistance, high elasticity, tear strength and elongation. It is easy to aging in the air, it becomes sticky when it is heated, it swells and dissolves in mineral oil or gasoline, it is resistant to alkali but not strong acid.
Advantages: good elasticity and acid resistance.
Disadvantages: not resistant to weather and oil (vegetable oil resistant)
Uses: It is the raw material for making adhesive tape, rubber hose, rubber shoes, and is suitable for making shock-absorbing parts, products used in the liquid with hydroxide, such as automobile brake oil, ethanol and so on.
