About Polymer Reactor Technology

Based on more than 120 man-years of research experience, PRT designs and builds affordable setups, including service, training and warranty. The setup size can range from single-particle reactors to industrial pilot plant size. Based on professor Weickert's patents, PRT is developing components of new gas phase polymerization technologies and has a number of sophisticated labscale setups that can be used by our clients for commercial and academic research projects. We lease lab and pilot infrastructure.
