Chloroprene rubber (CR) is made of chloroprene as a monomer emulsion polymerization of polymers, since the twentieth century, 30 years by the United States DuPont developed successfully, first used in the shoe industry, because it is inexpensive, strong adhesive force, adhesive time is long, the activation temperature is low, not only to adapt to automated large-scale production, but also suitable for manual work, and quickly gained wide mᴐbibia.
