What are the significant advantages of neoprene outer coverings over other materials in terms of resistance to oil, solvents, acids and alkalis?

In the mechanical transmission system, lubricating oil is an indispensable part, but long-term infiltration poses a severe test to the stability of rubber synchronous belts. The chloroprene rubber outer coating has significant advantages in oil resistance compared with other materials such as nitrile rubber and polyurethane. The unique chlorine atom polar group in the chloroprene rubber molecule not only enhances the intermolecular force, but also significantly improves the resistance of rubber to oily substances. This means that in an industrial environment containing various mechanical lubricants, the chloroprene rubber outer coating can maintain its physical and chemical stability for a long time, effectively prevent oil penetration and expansion, and ensure the cleanliness and smoothness of the transmission surface. Thereby improving transmission efficiency and reducing energy loss.

In addition to oil resistance, the chloroprene rubber outer coating also has excellent solvent resistance, acid resistance, and alkali resistance. In the chemical, pharmaceutical and other industries, it is often necessary to face the erosion of various organic solvents and acid and alkali solutions. These chemicals are often highly corrosive and soluble, posing a serious threat to the stability of rubber materials. However, due to its unique molecular structure and chemical stability, chloroprene rubber can effectively resist the erosion of these corrosive substances. The chlorine atoms in its molecular chain not only increase the polarity of the rubber, but also improve the resistance of the rubber molecules to solvents and acid-base substances, ensuring that it can maintain stable performance in complex and changeable industrial environments.

The reason why the chloroprene rubber outer coating has achieved such significant advantages in oil resistance, solvent resistance, acid and alkali resistance is due to the technological innovation and process improvement behind it. In the production process, by carefully controlling the polymerization reaction conditions of the chloroprene monomer, chloroprene rubber with excellent performance can be produced. At the same time, the use of advanced surface treatment technology and coating technology can further enhance the protective performance of the chloroprene rubber outer coating, making it more adaptable to complex and changeable industrial environments.

Due to its excellent chemical stability, the chloroprene rubber outer coating is widely used in various fields. In the transmission system, it is used as the outer coating of the rubber synchronous belt, which can effectively improve the transmission efficiency and extend the service life; in chemical equipment, it is used as an anti-corrosion coating and sealing material to resist the erosion of acid and alkali solutions, ensuring the durability and safe operation of the equipment; in the food, medical and other industries, it is also favored for its good biocompatibility and non-toxicity.
