The use of contaminated, even microscopic amounts of impurities, chemical components for the manufacture of electrochrome systems leads to failure to achieve the required parameters, as well as accelerated degradation of the resulting electrochrome system. To eliminate impurities, all substances used in the manufacture of electrochromic compositions require an increased degree of purification. Octoglass has a sufficient stock of its own equipment for the purification of chemical components used in the manufacture of electrochromic systems.

Propylene carbonate of increased degree of purification is used not only as a solvent for the manufacture of polymer or hybrid electrochromic systems, but also for various chemical operations. Octoglass chemists have at their disposal - own rectification system of propylene carbonate purification, which achieves the highest available degree of purification of the substance for industrial use.

In addition to cleaning chemical components, Octoglass specialists can perform custom synthesis of organic components, including custom synthesis of polymers.
