The chemical branch of the Group is represented by the companies, which produce industrial plasticizers and anhydrides.
In particular, these companies produce phthalic and maleic anhydrides and plasticizers for chemical, mechanical rubber and other industries.
The key competences of these companies are production and sale of DOP (dioctylphthalate) and DINP (diisononyl phthalate) plasticizers.
Dioctylphthalate (DOP) is a strategic raw material for polyvinylchloride processing enterprises as well as for manufacturers of mechanical rubber goods and coating materials. It is widely used as a plasticizer for vinyl polymers, resins and rubbers, for the production of synthetic leather, in the manufacturing of cold-resistant rubber products, polymer construction materials, packaging films, wallpaper etc.

Diisononyl phthalate (DINP) ) is used as a total or partial DOP substitute in the manufacturing of various PVC plastic compounds. In particular, it is used for the production of all types of plastic compounds (shoe and cable plastic compounds, resin plastisols, floor cloth, films, etc.)

Dioctylphthalate and diisononyl phthalate are poured into aluminium and steel rail tank cars (60 tons) and tank trucks (22 tons), plastic drums or barrels with the capacity of 250 kg and more for storage and transportation.
The available process capabilities allow increasing production capacity and expanding the range of plasticizers, in particular, by introducing an additional production flow chart.
