SNR237T

 SURPREN TM SNR237T

Introduction
Chloroprene rubber SNR237T is a specific grade, it is obtained by mercaptan modified and Chloroprene monomer which is polymerized in emulsion with medium crystallization tendency. It can be seen as an equivalent to Denka M-130H of Japan.

Characteristics

*  A very high Mooney viscosity and a medium rate of crystallization and the same properties as SNR238 and SNR239;

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

*  Can be used alone or combination with SNR242, has prolong the effect of open bonding time;

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

*  The same applied properties as Denke M-130H of Japan.

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