With the goal of producing new precursor materials for energy efficient carbonization

Rudolstadt. The EPC Group, in cooperation with the Thuringian Institute of Textile and Plastics Research (TITK), developed the necessary conditions for the synthesis of modified polycarbonates and acrylonitrile copolymers on a pilot scale. Polycarbonates are synthesized in a two-stage melt-polycondensation unit with annular disk reactor. They will be used in the development of new materials, such as for flame retardant applications.

With EPC’s patented 20L PAN reactor, acrylonitrile copolymers can be produced in kilogram scale by suspension polymerization in water. These are produced alongside research projects from wet spinning plant to precursor filaments production for carbon fibers. The carbonization of carbon fiber takes place in TITK’s in-house carbonization plant. This carbon fiber project community has the goal of developing and optimizing new precursor materials, which will enable more efficient carbonization.

Pilot Plant for Acrylonitrile Polymerisation

The polymerization processes built in the polymer synthesis pilot facility are closely linked with further processing units. Thus, the entire value chain from raw material to the end material or fibers is represented. With in-house analytical methods and material tests, the properties of the materials can be thoroughly examined.

Thermal analysis methods that are available are for example thermal gravimetric analysis with infrared spectrometer (TGA-IR), differential scanning calorimetry (DSC) and thermomechanical analysis (TMA), which can simulate carbonation up to 1500 ° C. Furthermore, extensive rheological measurements can be carried out on thermoplastic materials.

Analyses are also carried out at each stage of the process in order to optimize every procedure. Raw material input analysis in cooperation with the analytical department of TITK and OMPG is a part of the program at the pilot facility. In the future, the polymer synthesis team will increasingly turn its focus to polymers from renewable raw materials.
