Chloroprene rubber CR244
This product is a tacky chloroprene rubber synthesized via emulsion polymerization, using diisopropyl dithiocarbamate or dodecyl mercaptan as a regulator and chloroprene as the monomer. It is equivalent to the Japanese Denka Company's A series, such as A-90, and the American DuPont Company's AD series, like AD-20.

Product Description
This product is a tacky chloroprene rubber synthesized via emulsion polymerization, using diisopropyl dithiocarbamate or dodecanethiol as a regulator and chloroprene as the monomer. It is equivalent to the Japanese Denka Company's A series, such as A-90, and the American DuPont Company's AD series, including AD-20.
Product Performance
Crystallizes rapidly, with a density of 1.23, appearing as milky white or off-white flaky material. Its molecular structure is highly ordered, resulting in strong cohesive forces and maintaining excellent adhesive strength even at room temperature.
Main uses
It is the primary base material for chloroprene rubber adhesives. Widely used for self-adhesion or mutual bonding of rubber, leather, fibers, metals, wood, cement products, and more.
