Product Description
This product is a chloroprene polymer formulated with dodecyl mercaptan as a regulator, resulting in an adhesive-type chloroprene rubber produced via emulsion polymerization of chloroprene 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
Density: 1.23, milky white or off-white flake-like material.
