Ultra high dispersal MF-UB screw
Click an image to enlarge it.
The efficient dispersal effect of melted resin with the use of the optimal design of Dulmage type screw is effective in eliminating color heterogeneity for materials in which color heterogeneity easily occurs for PP as well as for combinations of master batches.
MF-UB screw
Features
- High mixing / high dispersibility
Optimum for poor pigment and filler dispersibility by using special high dispersibility mixing. - Uniform resin temperature
Mixing performance analysis
High dispersibility of MF-UB (molding sample comparison)
- Resin: PP (for large automobile parts)
- Master batches: Low-cost model with a low melting point additive. Difficult to eliminate color heterogeneity in this type.
Mixing ratio MFR (g/10min) Melting point (°C) Principal material 100 31 164 Master batches 3 34 102, 122, 163 - Screw size: φ62, Screw RPMs: 193 RPM, Back pressure: 5 MPa
