W. R. Grace & Co. has contracted to license its UNIPOL® PP Process Technology to PDH Polska S. A. for a new facility in Police, Poland. With a capacity of 400 kilotons per year, the PP line is expected to begin operations in 2022. Grace's gas-phase UNIPOL® PP Process Technology provides the most advanced and broadest range of PP homopolymers and copolymers in the industry. As the simplest of all PP process technologies, with fewer moving parts and less equipment than any alternative, its reliable, stable, and predictable operation leads to lower capital, operating, and maintenance costs.
