Chloroprene rubber (CR) is a synthetic rubber possessing excellent mechanical strength, flame retardance, and bonding strength, coupled with well-balanced combination of weatherability and resistance to ozone, heat and oil. CR is widely used in industrial products, cables, adhesives and dipping goods. CR is generally classified according to its Mooney viscosity (MV), crystallization rate and modification type of molecular structure which is modified by Mercaptan, Sulfur or Xanthogen. Depending on combinations of these characteristics, Denka has lined up various grades in order to meet wide-ranging customers
