A Zhejiang biodegradable materials factory has significantly improved its dispersion efficiency by adopting the TST-52

2025-09-01

Customer Background: The customer produces PBAT+starch biodegradable materials and has extremely high dispersion requirements.

 

Problems Encountered: Insufficient mixing in the twin-screw extruder led to starch agglomeration, affecting film processing performance.

 

Solution: Adopting our TST-52 triple-screw extruder, configured with:

• Multi-meshing triaxial structure
• Fine dispersion mixing zone
• Negative pressure venting
• Hot-cut water-cooled granulation

Performance:

• Dispersion efficiency increased by 30%
• Feed temperature more stable, extrusion pressure fluctuation reduced by 40%
• Film tensile properties improved, yield significantly increased
