Chloroprene Rubber

SN-244X
The SN-244X series consists of general purpose, sulfur modified polychloroprene rubbers produced using emulsion polymerization
process technology. SN-244X has a high crystallization rate and can be seen as an equivalent to the CR-244 grade in terms of
general performance. However, SN-244X is superior to CR-244 in solubility and product color.
Properties and Characteristics
SN-244X has fast rubber crystallization speed, strong cohesion, and good storage stability. Its glue color is shallow in toluene or
mixed solvents. It has high cement strength, good adhesion, easy coating capabilities, and is easy to work with. SN-244X
compounds exhibit good oil resistance, chemical resistance, ozone and aging resistance as well as sunlight resistance, fire
resistance and electrical properties typical of polychloroprene rubber.

Applications
Applications available in the SN-244X series are similar to that of CR-244. As a basic adhesive raw material, SN-244X can be used
alone or in combination with other types of polychloroprene rubber. Adhesive bonding applications include rubber, leather, fabric,
leather, plastic, wood, paper, glass, ceramics, concrete, metal and other materials. It can also be used for shoes, furniture, sofa,
mattress, toys, handicrafts and rubber product repair industries.
