Development of neoprene rubber

In later 20th Century 20s with the emergence of emulsion polymerization method, neoprene rubber began to have a small amount of production. In 1931 neoprene rubber sheet was sold by the United States DuPont, named ” Dopp Ryan”, and then changed its name to “Neop Lane”. For a long time, the supply of this kind of rubber has been basically monopolistic by the DuPont Company. To the 50-60’s, Germany, Britain, Armenia, China, Japan and France also began producing neoprene rubber. Due to polymerization conditions, with the difference of dosage & nature of regulator and stabilizer and different nature, monomer ratio and different nature and the composition of the copolymer, the produced neoprene rubber is different on the storage stability, crystallization ability, and the possibility of manufacturing colored rubber, viscosity, and process performance are different.

Neoprene rubber is a common special synthetic rubber polymerization by chloroprene (2-chlorbutadiene-1,3) monomers. It has not only the general rubber excellent physical properties, and also possess good weather resistance, oil resistance, chemical resistance and other excellent features. Therefore, CR rubber holds a special position among the various kinds of synthetic rubber.
