Extrusion 7-2019

57 Extrusion 7/2019 Materials – Interview DOTP Plasticizer for PVC-Processing Denis, could you please tell me about the product that SIBUR launched this spring in Perm? What type of processing was it designed for? Denis Gerber : SIBUR Holding launched the production of dioc- tyl terephthalate plasticizer (DOTP) located on the territory of Sibur-Khimprom, Perm. The official opening took place in May. DOTP is demand in the production of floor coverings, membran- es, films, wallpaper and many other products, and from plasti- cized PVC. Accordingly, the types of processing can be different depending on the final product: extrusion, calendering, injec- tion molding. I guess PVC processors are already using some plasticiz- ers, so could you tell me about competitive strengths of your DOTP? Gerber : If you compare DOTP with other primary plasticizers, such as DOP (dioctyl phthalate) and DINP (diisononyl phthal- ate), then DOTP main advantages include its environmental friendliness and safety for human health. For more than ten years, the USA, Europe and many other countries have had severe restrictions on phthalate plasticizers in the production of children's toys, packaging, hygiene and cosmetics. Phthalate plasticizers – group of substances based on phthalic anhydride (such as DBP, DOP, DINP, DIDP and seve- ral others). The main raw material for DOTP is terephthalic acid and this type of plasticizer fully complies with modern interna- tional requirements for the safety of chemical compounds. DOTP also has a number of advantages: • low volatility, which significantly increases the lifecycle of the final product; • low temperature fragility; • expansion of operating temperatures of cable products from -40 +70 to -45 +80 °C. The quality of Sibur DOTP corresponds to inter-row benchmarks, and in terms of parameters such as the content of the main substance, color, thermal stability exceeds them. What foreign markets are you planning to enter with your DOTP? Gerber : One of the main aims of the project is to replace the import of plasticizers in the Russian Federation and to meet the needs of local manufacturers. At the same time, analysis of po- tential markets showed that there are significant DOTP deficit on the European Union market, amounting to approximately 200 thousand tons per year, which opens a window of opportu- nity for export to this region. Also interesting is the CIS market. Do you already have any cases of successful implementa- tion of your DOTP? Are there probably any big brands among your new customers? Gerber : SIBUR is developing cooperation with partners in all segments of plasticized PVC processing. In each industry, there are several leading companies where DOTP has already been implemented or testing is at the final stage. For example, Bashplast, BSK and Hemkor in the segment of cable and wire products. Tarkett, Beaulieu, IVC Group in the flooring segment. Technonikol and Penoplex in the segment of PVC membranes, Clarity in the segment of PVC film and this list can be continu- ed. The previously noted competitive advantages of Sibur DOTP, such as environmental friendliness and safety, improving the operational quality of finished products, high and stable quality, make it possible to efficiently and without restrictions introduce this plasticizer at all enterprises of plasticized PVC processors.
