Polytevo Series Recirculating Single-Screw Extruder
Product Detail
Polytevo Series Recirculating Single-Screw Extruder (ACS-7008ZM) is a laboratory single-screw extruder with a circulating flow channel and a reversing valve, a Ø20 mm screw at 1–120 rpm, six temperature control zones and a maximum temperature of 380°C.

The ACS-7008ZM is a single-screw extruder specially developed for mixing new materials. Its circulating flow channel and reversing valve let the material circulate or be extruded, and it can be used on test benches or in fume hoods. It is suitable for laboratory mixing, plasticization and extrusion of polymer materials such as engineering plastics, modified plastics and masterbatches.
