sustainable ideas in plastic

Materials development

The speed at which new materials come onto the market to adapt to trends and customer requirements is constantly increasing. New developments are expensive and not always necessary. To ensure that you remain flexible and can actively respond to changing requirements, we offer you the modification of existing plastics with appropriate additives. The customized compounds produced by twin-screw extrusion are evaluated and optimized with regard to rheological, mechanical and processing changes until the plastic fits. In addition to plastic modification, we also intensively pursue the development of novel, sustainable materials. In materials development, the focus is on generating natural-substance-based bioplastics and on processing and optimizing the properties of recycled materials.

Our materials development services in detail

Twin-screw extrusion:

  • Filling, reinforcement, additivation, chemical modification (reactive extrusion).
  • Blending of plastics
  • Physical, chemical modification of natural materials
  • Preparation of bio-based plastics
  • Preparation and property optimization of recycled materials


Characterization of the flow behavior of materials by means of:

  • Torque rheometer
  • Extrusion rheometer (round, slotted capillary nozzle)
  • Plate-plate (cone-plate) rheometer
  • Melt rate rheometer (MVR / MFR)
  • Solution viscosity (VZ)

Rheological tests

Film tape extrusion by means of:

  • Laboratory extruder with wide slot die
  • Three-roll haul-off
