  • Logistics Info
Chlorprene rubber SN238 is a general purpose,it is obtained by mercaptan modified and Chloroprene monomer by emulsion polymerization with medium rate of crystallization,for using a Narit recipe and process technology.It can be seen as an equivalent to Dupont WHV-100 of the United States.

Chloroprene rubber SN 238 is ,which has the same properties as SN231 and SN 232 except for its higher Mooney viscosity. An outstanding characteristic of this grade has excellent cohesion,in the production,vulcanizate maintains its good physical properties when a large amount of fillers and oil are added.It has a medium rate of crystallization and good solubility,can regulate the adhesion tack to keep a time and improve heat resistance.It has the same processability as Dupont WHV-100 of the United States.
According to standard Q/SNYF02.08-2009
