FARREL POMINI and have conducted joint research to compare the processing of on the Twin Screw Extruder and the Farrel Continuous Mixer (FCM™). The objective of the study was to evaluate the effects on molecular weight loss in PLA while adding a talc mineral filler.

Ingeo polylactide (PLA) or polylactic acid is a derived from sustainable, renewable resources, such as corn starch, cassava, or sugarcane. It is often used in food packaging and fiber/nonwovens industries and is one of the most highly utilized bioplastics in the world.

Farrel Continuous Mixer Technology for Better MW Retention
The study found that the FCM™ resulted in significantly better molecular weight retention. Trials showed a 95% molecular weight retention when using 50% filler and 88% retention when using 60% filler.

In addition, the trials demonstrated that FCM™ technology provides other distinct advantages over regarding:

  • Lower melt temperature
  • Lower specific energy

The minimal residence time and efficient mechanical shear respectively, that are the cornerstones of the FCM™ operating principles, are responsible for these outcomes.

Improved Physical Properties
PLA is often compounded with mineral fillers and/or additives to improve physical properties. As compared to Twin Screw Extruders, the benefits of the FCM™ would allow for:

  • Lower processing costs
  • Higher mineral fill levels
  • Improved physical properties

The results are being presented at various conferences worldwide beginning with ANTEC® 2019, March 18 – 21 in Detroit, Michigan USA.
