CHLOROPRENE RUBBER SN237T



Introduction
     Chloroprene rubber SN237T 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

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

2. Excellent cohesion and better solubility, especially in preparing adhesive;

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

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

5. 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.
