Filler Masterbatch

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 %.
