USEON design the extruders for filler Masterbatch, according to the output, formula and final application as your request.
Filler Masterbatch are concentrates of CaCO3 or Talc or BaSO4 in a polymer base.

The Basic Formula
Base Resin | Filler Type | Additives |
---|---|---|
PE | CaCO3 55-85% | PE wax |
PP | Talc 25-60% | White Oil |
PS | BaSO4 40~70% | Anti oxidant |
Applications
FILLER masterbatches are used in injection, blow-moulding, film(One layer or Multiple layer), sheet and tapes applications. They offer the following advantages:
a) Injection & blow-moulding
- Lower raw materials cost, as they are usually more economic than polymer resins
- Increased output due to faster mould cooling
- Reduction of colour masterbatch requirement
- Higher resistance to heat deflection, higher rigidity and stiffness
- Improved dimensional stability, weldability and printability
Addition rate of FILLER masterbatches in injection & blow-moulding applications can be up to 50 %, however, most usual levels are between 5-30 %.
b) Film, sheet, sacks, bags, raffia
- Lower raw materials cost, as they are usually more economic than polymer resins
- Reduction of colour masterbatch requirement
- Higher stiffness, paper-like effect
- Improved weldability and printability
- Improved anti-blocking properties
- Better bubble stability
Addition rate of FILLER masterbatches in film applications is 2-20 %.
c) PE & PP tapes
- Antifibrillation (also known as anti splitting)
- Lower raw materials cost, as they are usually more economic than polymer resins
- Reduction of colour masterbatch requirement
- Higher stiffness
- Improved weldability and printability
- Improved anti-blocking properties
- Improved weaving ability
- Easier processing
Usual addition rate of FILLER masterbatches in tapes is 3-8 %.
d) HDPE & PP Pipe
- Replaceing expensive white masterbatch with its high white degree
- Lower raw materials cost, as they are usually more economic than polymer resins
- Higher stiffness
- Smooth pipes with lower coefficient of friction to better prevent them from blocking
- Being less possible to be brittel in low temperature due to its excellent cold resistance
Usual addition rate of FILLER masterbatches in tapes is 5-30 %.
Processing of Filler Masterbatch
a) Feeding System
There two feeding system:
Volumetric feeding system
- Weight the raw material separately according to the formula
- Then put all the material into high speed mixer for 5~10minutes mixing
- Discharge the material into spiral loader
- Loading the material into the hopper of volumetric feeder
Loss-in-weight feeding system (automatically and higher accuracy)
- Put the raw material into each tank on the ground.
- Vacuum loader will convey each component into the storing silo.
- The raw material will fall into the loss-in-weight feeder automatically. The feeding system will feed the material separately into extruder according to your formula setting one the HMI.

b) Technical Specifications of Extruder
According to your application & output, there’re many different choice on extruders.
