Neoprene ie neoprene.
  Chloroprene rubber (Neoprene). Chloroprene (i.e., 2-chloro-1,3-butadiene) polymerization carried α- produced as the main raw material of synthetic rubber, has been widely used for the weathering products, adhesive shoe soles, coatings and rocket fuel .
  Neoprene are emulsion production, the production process more than a single batch polymerization reactor. The polymerization temperature is more controlled at 40 ~ 60 ℃, the conversion rate was about 90%. Polymerization temperature, the final polymerization conversion rate is too high or the process into the air (oxygen) will result in lower-quality product. Production by sulfur - thiuram (four groups A thiocarbamoylbenzothiazol disulfide) system to adjust the molecular weight. Sulfur - The main drawback of the system is that thiuram disulfide bond is not stable enough, this is one of the important factors affecting the storage of. If using thiol molecular weight regulation can improve this performance. Chloroprene rubber and synthetic rubber in general different, it should not be sulfur cured, but with zinc oxide, magnesium oxide and other cure. Neoprene varieties and grades are more synthetic rubber grades up to a plastic types.
