[Polychloroprene Rubber SN232] 
[CR232] 
SN232 is a general purpose, mercaptan modified polychloroprene rubber produced using a Nairit recipe and process technology. SN232 has a medium crystallization rate and can be seen as an equivalent to the W grade from DuPont,DENKA M-40,Lanxess baypren 210.

A. Properties and Characteristics 
This CR grade gives compounds with excellent physical properties and plasticity. SN232 shows excellent processing capabilities when compared with CR232. Lt can be compounded without prior rubber milling and resists molecular weight degradation except under the highest shear conditions. Compound surfaces of rubber are smooth and tend not to adhere to the rolls while milling. SN232 can easily be mixed with other chloroprene rubbers. Compounds of SN232 have very low compression set and excellent elasticity. Generally, accelerators are added to compounds of SN232 but cure rate and process safety can be widely varied to suit the requirements, especially if mixed with other rubbers. SN232 compounds exhibit the good oil resistance, chemical resistance, ozone and aging resistance as well as the sunlight resistance, typical of polychloroprene. Also typical are their good fire resistance and electrical properties.

C. Applications 
The wide range of viscosities available in the SN23x series allow the appropriate amount of filler and plasticizer to be added to obtain compounds suitable for most applications where CR is the rubber of choice. Particular examples of their intended applications are: Conveyor belts, extruded profiles, hoses, seals and wire and cable sheaths. These grades can also be used for formulating adhesives, particularly for adhesive plasters.
