Product Description
This product is a chloroprene polymer formulated with sulfur and diisopropyl dithiocarbamate as mixed regulators, resulting in a general-purpose chloroprene rubber produced via emulsion polymerization of chloroprene monomer. It is equivalent to DuPont's GW-type rubber from the United States.
Product Performance
The crystallization rate is moderately low, with a density of 1.23. It appears as off-white or light brown lumps. It exhibits high tear resistance and superior processing performance compared to sulfur-regulated rubber types.
Main uses
This product has a wide range of applications, including the manufacture of rubber hoses, tapes, cable jackets, and other rubber products.
