Applications of Silane LS-CMMS


  • CMMS is an efficient modifier for MgCl2 supported Ziegler-Niegler catalysts in propylene polymerization and copolymerization to improve the stereo- and region-selectivities and activities of the catalysts.

  • CMMS has been used in Spheripol, Innovene, Novolen, Spherizone, Hypol, Unipol.

  • CMMS can be used with all kinds of MgCl2 supported Ziegler- Natta catalysts produced by different manufacturers.


Package & Storage of Silane LS-CMMS


  • In 180kg drum

  • Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep away from acid and alkali. Keep in unopened containers.

  • Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
