About PRT


January 2005:    PRT was founded

                                  => export of a gas phase pilot plant

                                  => patent licenses sold to a leading PO company ("draught reactor" and "tubular (slugging) reactor")

November 2006: PRT found a new home under the roof of PROFILAN GmbH & Co KG, in Legden, Germany.

                       100m2 laboratory and 80m2 out-door facilities with the focus on

                                  => first fluidization studies

                                  => UHMWPE processing

                                  => gas / liquid purification units

                                  => catalytic polymerization of ethylene

2008:              move to Heek, rental of 300m2 area

                                  => fluidization studies

                                  => RAM extrusion scaling up to 100mm rods

2010:              move to Ahaus, Wessum, 1800m2, 600m2 research hall;

                                 => large transparent fluidization units in operation (1m diameter, 3000m3/h)

2011:              erection of a second research hall for pilot plants, 600m2

                                 => design and manufacturing of high pressure laboratory equipment for the Johannes-Kepler University, Linz, Austria 

                                 => guest professor ship of Prof. Weickert at JKU

2012:              400 kg UHMWPE produced in PRT's slurry pilot plant

2013:              high temperature-co-polymerization reactor operational

                     first contract with a leading Bio Science group

2014:             pilot plant completion: 800-Liter stirred tank, 1000-L Hosokawa vacuum dryer; wiped film evaporator

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.
