Chloroprene rubber is produced by lotion polymerization, and the production process is mostly single kettle batch polymerization. The polymerization temperature is mostly controlled at 40~60 ℃, and the conversion rate is about 90%. High polymerization temperature, high final conversion or air (oxygen) entering the polymerization process will lead to product quality degradation. The molecular weight is adjusted by sulfur-turrum (tetraalkylmethylaminothiocarbonyl disulfide) system in production. The main disadvantage of sulfur-turam system is that the sulfur bond is not stable enough, which is one of the important reasons affecting the storage. If the molecular weight is adjusted by mercaptan, this performance can be improved. Unlike general synthetic rubber, neoprene is vulcanized with zinc oxide and magnesium oxide instead of sulfur.

Neoprene can be used as an insulator in power transformers, bulbs and other electrical applications due to its fireproof and anti-static properties. Neoprene is also used for electrical sealing gaskets to provide waterproof sealing, heat resistance and anti-static, and to prevent the entry of dust and pollutants.
