Biopolymer Compounding Extruder Machine

Compounding of biopolymers constitutes the first preparation process for the modification of plastics by means of extrusion following the production of the base polymer. Throughout the preparation, characteristic feature of the plastics can be selectively changed.

Hereby, it is adapted to the next process and targeted product characteristics.The plastic is melted inside the extruder where it is blended with additives, fillers, reinforcing materials or a combination of them. After homogenization and degassing of the compound, it is formed – usually as strands – by using a tool, then cooled and processed into plastic granules. In the compounding process, numerous effectors arise before processing and during it. Depends on the type of plastic, these factors are evident in variable degrees and affect it’s mechanical, thermal, (chemical) and rheological properties as well.
