GSmach provides advanced pelletizing line for all kinds of filler masterbatch.
We 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.
Table of Contents
The Basic Formula
| Base Resin | Filler Type | Additives |
| PP | CaCO3 55-85% | PE wax |
| PE | 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
Replacing 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
1.Weight the raw material separately according to the formula
2.Then put all the material into high speed mixer for 5~10minutes mixing
3.Discharge the material into spiral loader
4.Loading the material into the hopper of volumetric feeder
Loss-in-weight feeding system (automatically and higher accuracy)
1.Put the raw material into each tank on the ground.
2.Vacuum loader will convey each component into the storing silo.
3.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.
(Loss-in-weight feeding system & Side Force Feeder)
b) Technical Specifications of Extruder
According to your application & output, there’re many different choice on extruders.
