⚙️ Product Description
The Coperion STS 95 Twin Screw Extruder is a high-performance co-rotating, intermeshing twin-screw compounding system engineered for continuous production of masterbatches, polymers, and specialty compounds.
Equipped with two 95 mm diameter screws and a 40:1 L/D ratio, this extruder provides superior mixing, dispersion, and devolatilization performance for a wide variety of thermoplastics and additives.
The system features 10 barrel sections, of which 9 are electrically heated and water-cooled, ensuring precise temperature control and consistent melt quality.
Driven by a 280 kW DC drive motor through a Siemens gearbox, the extruder achieves up to 300 RPM screw speed, enabling high throughput and efficient processing.
Included is a Coperion STS 95 twin-screw side feeder and a frame-mounted die head, ideal for compounding, reactive extrusion, and blending applications.
