Chloroprene rubber SN237T
Blue Star TM SN237T
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, for using a Nairit recipe
and process technology. 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 SN238
Excellent cohesion and better solubility, especially in preparing adhesive;
Can be used alone or combination with SN242, 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.
White or light yellow chips, with talcum as a release agent, no mechanical impurities.
Broodfield solution viscosity, 10% toluene solution at 25 ºC,
1510 - 2700
Mass fraction of volatiles, wt. % ≤ 0.8
Mass fraction of ash, wt. % ≤ 1.0
Denka, Japan: M-130H
Lanxess, Germany: 243-2, 253-1
SN237T, which is mainly suitable for production goods of highly loading and preparing adhesive cement,
production things of the conveyor belts, a variety of hoses, rubber seals, and some hard good.
