LOOP TWIN SCREW EXTRUDER

“ULTnano” series is loop type twin screw extruder for the purpose of collecting initial basic date in the compounds.
  • POINT01
    Original loop twin screw extruder

    Various factors such as residence time and compounding conditions can be freely set by the loop line. Since possible to evaluate ultra-small amount with a few grams, it can easily contribute to the collection of basic date.

  • POINT02
    Versatile screw formation

    Easily collect the basic date such as the torque, screw speed, barrel temperature for the R&D.

Applications

The recirculating ULTnano at the forefront of R&D

“Only a little material to spare,” “conditions to vary in fine steps,” “data needed along the way”:
in the assessment stage before moving to mass production, very small volume evaluation shows its strength.

SAMPLE SIZE
Twin screw kneading from just a few grams
RESIDENCE TIME
Residence time set freely
PROCESS DATA
Machine load logged over time
Small Volume Screening of New Materials

Even newly synthesized polymers available only in small quantity can be assessed for kneadability and dispersibility from a few grams, so many candidates are narrowed down quickly.

Freshly Synthesized Polymers Basic Evaluation of New Grades Quick Screening of Candidates
Basic Data for Nanocomposites

The high shear of repeated loop circulation drives deagglomeration and dispersion of nanofillers, while we capture the relationship between kneading history and dispersion state.

Dispersion Evaluation of Nanofillers Deagglomeration under High Shear Linking Kneading History to Dispersion
Trial Evaluation of Rare and Costly Materials

Because material circulates inside the machine rather than being discharged, none of a valuable feedstock is wasted, and trial evaluation is possible on a scale of a few to several tens of grams.

New Biopolymers Special Functional Additives Trials from Just a Few Grams
Observing the Kneading and Reaction Process

By logging machine load, melt temperature and melt pressure over time, the progress of reactive extrusion and dispersion can be followed along a clear time axis.

Reactive Extrusion Behavior over Time Monitoring of Torque and Melt Temperature Tracking Dispersion Progress over Time
Developing Kneading Conditions

Each condition is varied independently to find the optimum.

Variation of Residence Time Optimization of Screw Speed and Temperature Screw Formation Study
Setting Conditions Ahead of Mass Production

Ahead of full scale compound design and machine selection on continuous extruders, we provide reliable baseline data and judgment.
