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
