M-Series

 SUNPREN CSM  M-Series

M- series is produced by new non-solvent technology , so this series contains no harmful organic solvent such as carbon tetrachloride, it is environmental friendly and has no harm to operator’s health, another point is, though this series’ mechanical property is a little lower than H-series, it can meet the technical demand of most general rubber application, and its price is considerably cheaper than H-series, so this series is a economic choice for many general rubber application.

The solubility of M-series in some organic solvent is poorer than H-series, so it is not a good choice for coating and adhesive application.
