SmartMelt - Filtration Patented Process-Technology

Highly Efficient Filtration of Polymer Melts Through Viscosity Adjustment

The patented process enables targeted viscosity modification and filtration of polymer melts. By precisely adding CO₂, the viscosity of the melt is reduced before the filtration process. This facilitates filtration at lower pressure and temperature, reducing energy consumption and protecting system components. After filtration, the CO₂ is removed from the melt in a cascade extruder using a high-performance degassing unit, restoring the original viscosity—ideal for subsequent pelletizing.

CO₂ acts not only as a viscosity reducer but also as a stripping agent, enhancing the intrinsic purification of the melt.

The combination of feed screws, melt filter, degassing unit, and pelletizing module ensures an efficient, safe, and economical process.
This technology is particularly suitable for processing plastic waste that must meet high filtration standards and produce regranulates with extremely low emission values during further processing.

Why SmartMelt - Filtration?

Filtration at reduced viscosity means lower melt pressure and longer filter element service life.

Lower thermal stress on the melt due to reduced energy input

CO₂ also acts as a stripping agent, enhancing degassing performance.

The result is a high-quality, homogeneous plastic granulate.
