Chemical Industry

The chemical branch of the Group is represented by companies which produce industrial plasticizers and anhydrides.

In particular, these companies produce phthalic and maleic anhydrides and plasticisers for chemical, mechanical rubber and other industries.

>

Core activities of these companies include production and distribution 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 plasticiser for vinyl polymers, resins and rubbers, for artificial leather production, in manufacturing of cold-resistant rubber products, polymer construction materials, packaging film, wallpaper etc.

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

Dioctylphthalate and diisononyl phthalate are poured for storage and transportation into aluminium and steel rail tank cars (60 tons) and truck tanks (22 tons), plastic pots or barrels with the capacity of 250 kg and more.

Existing process capabilities allow expanding production capacity and range of plasticizers, in particular, by introducing an additional production process flow.

Chemical enterprises of Aurum Group also produce phthalic and maleic anhydrides and their modifications.

Phthalic anhydride is an important output product of manufacturing of various derivatives of phthalic acid, esters, phthalimide, phthalonitrile etc. Manufacturers of plastics and coating material widely use phthalic anhydride for plasticizers production. The anhydride is used in aviation fuel, in manufacturing of colouring agents, medicinal drugs and oil admixtures. It is also used in rubber and tyres production as a precuring inhibitor. Another application of the anhydride is production of plasticizers, which are used, in turn, for manufacturing of floor cloth, cables and shoes, etc.

Manufactured products:

Phthalic anhydride (prime product of distillation) is used in production of alkyd resins, varnishes, plasticizers, as well as in other organic synthesis processes.

Phthalic anhydride (commercial-grade) is used in production of plasticizers, alkyd resins, colouring agents, medicinal drugs and polyester resins, as well as in mechanical rubber industry.

Phthalic anhydride (bottom product of distillation) is used in production of plasticizers and anti-corrosive materials, and for mechanical rubber and tyre industry.

Maleic anhydride is used in production of resins, superficially active substances, coating materials, epoxy resins solidifiers, fumaric acid and D, L-asparlic acid.

The enterprises produce phthalic anhydrid of A grade and pack it into bags of 50 kg net weight on pallets of 500 kg net weight. Maleic anhydrid of grade A is poured into rail tanks with electrical heating of 40 tons net weight.

Manufacturing facilities of Aurum Group enterprises allow to produce up to 20,000 tons of chemical products per year.
