**Technical Specifications:**
The system consists of two stages: the first stage uses a SHJ twin-screw extruder without a die, ideal for melting, compounding, and dispersing thermosensitive materials like PVC under no backpressure conditions. The second stage is a single-screw extruder (SJ), which operates at a lower speed to ensure stable melting, long-term compounding, and strand formation, reducing the risk of overheating.
**Representative Materials Processed:**
- **Mixing & Modification:** PE, PP, PS + SBS, PA + EPDM, PP + NBR, EVA + Silicon Rubber
- **Filling & Modification:** PE, PP, EVA, etc., + Calcium Carbonate, Talcum Powder, Titanium Powder
- **Functional Pellets:** PP, PA, ABS, PBT, etc., + Flame Retardants, Stabilizers
- **Biodegradable Pellets:** PE, PP, PS, etc., + Starch
- **Dual-Prevention Pellets:** PE + Fog Preventer, Stabilizer
- **Black Pellets:** PE, EVA, ABS, etc., + Carbon Black
