Comparison items | Reactor | Sigma Mixer |
Applicable viscosity range | ≤100,000cP (medium-low viscosity) | 10,000-5,000,000cP (high viscosity) |
Mixing mechanism | Mainly agitated (paddle/anchor) | Shear + extruder + folding (Z/∑-shaped blades) |
Temperature control accuracy | ±2℃ (jacket heating) | ±1℃ (staged temperature control) |
Dispersion capacity | General (depending on subsequent grinding) |
Extremely strong (can replace three-roll mill) |
Production capacity | Large (over 5000L) | Small to medium-sized (typically ≤3000L) |
Energy consumption | Relatively low | High (high shear requirements) |
Typical application | EVA-based, polyolefin hot melt glue | SIS/SBS-based/polyurethane hot melt glue |
