The JV will use the patents and technologies of Sibur. The NBR and IR plants are expected to have an annual capacity of 50,000 t/y each. The cooperation will be a two-stage process, with the NBR launch followed by the IR plant. Already at the end of April 2012, the parties have agreed to form a joint venture manufacturing NBR in Krasnoyarsk, Russia. The new JV will boost the existing NBR capacity of the Krasnoyarsk rubber plant from 42,000 to 56,000 t/y.
