Chloroprene rubber SN243
Blue Star TM SN243
Chloroprene rubber SN243 is high bond strength, it is obtained by mercaptan modified and Chloroprene
monomer by emulsion polymerization with high rate of crystallization, for using a Nairit recipe and
process technology. It can be seen as equivalent to Dupont AD-30 of the Unites State.
Characteristics Fast rate of crystallization and stronger cohesion;
Slightly higher viscosity than SN242;
Can be dissolved in toluene or mixed solvents;
Better solubility and uniformity than CR244 and good storage stability;
Adhesive cements prepared by SN243 is light in color and high bonding strength, quick good grips,
easy handling, the adhesion layer to keep a long time;
Good resistant to ozone, weather, oil, chemical corrosion and extension of the fine is not flammablThe same applied properties as Dupont AD-30 of the United States.
White or light yellow chips, with talcum as a release agent, no mechanical impurities.

SN243, which is a basic raw material of preparing adhesive cements, can be used alone or combination
with other types, preparing adhesive where a very higher tack is required. Adhesive is suitable for
bonding of the shoe industry, rubber leather, wood, metal and construction materials
