Filler Masterbatch

Base Resin	Filler Type	Additives
PE	CaCO3 55-85%	PE wax
PP	Talc 25-60%	White Oil
PS	BaSO4 40~70%	Anti oxidant

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 %.

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.

According to your application & output, there’re many different choice on extruders.
