As an important polymer material, Synthetic Rubber has a wide range of applications in production and life. As a synthetic high elastic polymer, it has replaced natural rubber in many fields. Let's take a look at the common types of Synthetic Rubber and their uses.

Styrene-butadiene rubber (SBR) is made by copolymerization of butadiene and styrene, and is the most produced general-purpose Synthetic Rubber. It is characterized by good wear resistance, oil resistance, heat resistance, and aging resistance. It is mainly used to manufacture rubber products such as tires, hoses, rubber shoes, and cables. In addition, styrene-butadiene rubber can also be used with other rubbers to improve the performance of the products. Especially in the tire industry, the use of styrene-butadiene rubber accounts for a large proportion because it can significantly improve the service life and driving safety of tires.

Butadiene rubber (BR) is made by solution polymerization of butadiene. It has a regular molecular structure, good wear resistance, and good cold resistance. Therefore, it is often used to manufacture highly elastic rubber products such as tapes, hoses, seals, etc. In low temperature environment, butadiene rubber can still maintain good elasticity to ensure the normal operation of related equipment. It can be used with other rubbers. Butadiene rubber is mainly used to manufacture tire treads, conveyor belts and special cold-resistant products. In tire manufacturing, butadiene rubber can improve the wear resistance and service life of tires.

Isoprene rubber (IR) is copolymerized by isobutylene and a small amount of isoprene. It is similar to natural rubber in structure and has similar performance to natural rubber, so it is called synthetic natural rubber. Isoprene rubber has excellent aging resistance and ozone resistance, and is mainly used to manufacture tires, rubber shoes, rubber hoses and other products. In tire manufacturing, isoprene rubber can improve the durability and safety of tires.

In addition to the above three common Synthetic Rubbers, there are many types of synthetic rubbers such as chloroprene rubber (CR), ethylene propylene rubber (EPDM), nitrile rubber, silicone rubber, etc., which play an important role in different fields. For example, chloroprene rubber has good oil resistance, solvent resistance and aging resistance, and is mainly used to manufacture cables, hoses and other products; nitrile rubber is mainly used to manufacture oil-resistant rubber products, such as fuel tanks, oil pipes, etc.; and EPDM rubber is widely used in automotive parts and building waterproof materials due to its excellent oxidation resistance, ozone resistance and UV resistance.

The manufacturing methods of Synthetic Rubber mainly include emulsion polymerization, solution polymerization and bulk polymerization. Emulsion polymerization is to disperse the monomer in water, add emulsifiers and initiators, and carry out polymerization at a certain temperature. The synthetic rubber produced by this method has a large output and low cost, and is suitable for large-scale production. Solution polymerization is to dissolve the monomer in an organic solvent, add an initiator, and carry out polymerization at a certain temperature. The synthetic rubber produced by this method is of high quality and stable performance, and is suitable for the production of high-performance synthetic rubber. Bulk polymerization is to polymerize the monomer in the absence of solvent. The synthetic rubber produced by this method has high purity and good performance, but the production process is complicated and the cost is high, which is suitable for the production of synthetic rubber for special purposes.

As an important polymer material, Synthetic Rubber has a wide range of application prospects in production and life. With the continuous advancement of science and technology and the improvement of people's requirements for material performance, the types and properties of synthetic rubber will continue to be improved and optimized, bringing more convenience and benefits to people's production and life. Its performance and application fields will continue to expand, contributing to the sustainable development of society.
