chloroprene Rubber

Chemical name CR244 chloroprene rubber
Properties
This product is chloroprene polymer as regulator with dithiodiisopropyl xanthate . The crystallization rate is fast, the density is 1.23, milk white or light brown lump, non pollution type. The molecular structure is regular, the cohesive force is high, and it has high bonding strength at normal temperature. It is the main base material of the chloroprene adhesive. It is widely used in rubber, leather, fiber, metal, wood, cement products and other self-adhesive or mutual adhesion. This product is similar to the Denka A-90, the United States DuPont Co AD-20 glue.
