Polymer Reactor Technology GmbH is specialized in catalytic olefin polymerization research and engineering.

About Polymer Reactor Technology

Based on more than 120 man-years of research experience, PRT designs and builds affordable setups, including service, training, warranty, HAZOP, FAT and SAT. Core experience has been developed for design and manufacturing of automated continuous miniplants for olefin polymerizations that allow producing industrial grades of almost all kinds of polyolefin-based products. The setup size can range from single-particle reactors to pilot plant size. PRT permanently increases the number of sophisticated experimental setups the use of which we offer to our clients within contracted R&D projects world-wide, preferrable focused on development of products and special process equipment.
