Filler Masterbatch
Filler masterbatch helps plastic manufacturers reduce raw material cost, improve stiffness, control shrinkage, and adjust processing behavior in different plastic products. Typical formulations contain calcium carbonate, talc, barium sulfate, or other mineral fillers combined with PE, PP, or another carrier resin.
High-filler formulations place high demands on the extrusion system. Powder feeding, torque capacity, screw design, venting, and pelletizing stability all influence the final result. For this reason, filler masterbatch production needs a robust twin screw extruder designed for high loading and continuous operation.
Nanjing Hundred Horse designs and manufactures co-rotating parallel twin screw extruders for filler masterbatch compounding. Our extrusion lines are configured for efficient powder incorporation, uniform filler distribution, and stable production at different filler ratios.
Key Process Requirements
- Accurate and stable powder feeding
- High torque capacity for heavily filled formulations
- Efficient incorporation of mineral fillers into the polymer melt
- Suitable venting for moisture and volatile removal
- Reliable pelletizing for uniform granule shape
- Consistent output under continuous production conditions
Typical Applications
- Blown film
- Injection molding
- Pipe extrusion
- Sheet extrusion
- Raffia and woven bags
- Packaging products
- Household plastic goods
With the right extruder configuration, producers can increase filler loading, improve processing stability, and manufacture pellets suitable for a wide range of downstream applications.
