 SURPREN TM SN236T

Introduction
Chloroprene rubber SN236T is a specific grade, it is obtained by mercaptan modified and Chloroprene monomer which is polymerized in emulsion with medium crystallization tendency, for using a Nairit recipe and process technology. It can be seen as an equivalent to Denka M-130L of Japan.

Characteristics

l  A very high Mooney viscosity and a medium rate of crystallization and the same properties as SN238 and SN239;

l  Excellent cohesion and better solubility, especially in preparing adhesive;

l  Can be used alone or combination with SN242, has prolong the effect of open bonding time;

l  In the production,vulcanizate maintains its good physical properties when a large amount of fillers and oils are added;

l  The same applied properties as Denke M-130L of Japan.

Appearance
White or light yellow chips, with talcum as a release agent, no mechanical impurities.
