Sensitive solution for bioplastics


ICMA SanGiorgio has delivered a second compounding line for production of biodegradable and bio-based compounds to SabioMate- rials, an Italian company founded in 2016 and based at Forlì. The first ICMA line installed at


SabioMaterials was specially designed for small production batches. This second line expands its industrial capa- bilities and will be used for production of its Terralix and Biodura ranges. “Our expertise includes polyhy-


droxyalkanoates (PHA), additives, and the production process of materials,” says SabioMaterials founder Alessan- dro Carfagnini. “We are expert in assessing novel ingredients, design- ing novel formulations and prototyp- ing novel materials. For these activities we rely on our laboratories and pilot scale plant.”

The new extruder is a 50 mm model and is equipped with a side feeder, liquid injection and degassing system. Screw configuration has been optimised within ICMA’s Innovation Hub and is specifically designed for mixing sensitive materials. The Carfagnini name may well be familiar to some in the compounding

arrangement was a powder coating application that called for a poex T27 clamshell extruder with high free volume. This has screws with a 27 L/D and 28.8mm diameter. The process section was designed to meet the


specific requirements of the task: OD/ID value is 1.80 to provide maximum free volume, the length of the process section is 24D, and the screw speed is 1,200 rpm to achieve the high shear required. Torque density is 12Nm/cm3

required the use of a poex cooling drum and poex twin screw feeder with stirring agitator, which runs based on a premix principle. “Due to the fact that it requires only a small area

and can easily be moved, the user gets the flexibility of a lab machine which can be designed and improved based on customer demands,” Yelken says. The QC3 concept from Entek was developed very much with small batch compounding in mind. Its QC3


33mm co-rotating twin-screw extruder,


originally introduced in 2018, includes all of the company’s QC3


features — Quick-Change, Quick-


Clean, and Quality Control. It has since become one of Entek’s most popular machines, plugging the gap between its 27mm and 43mm versions. “Our 27mm twin-screw extruder is excellent for


lab environments, and our 43mm is designed for small to medium-sized lots of compounds,” says Linda Campbell, Entek’s VP of Extrusion Sales. “We were getting a lot of requests from customers for something in between – a machine specifically designed for small lots, but with more output than the lab machine.”
