A masterbatch is a concentrated blend of pigments or additives that are encapsulated within a polymer carrier. It is used to introduce colour and other properties to polymers and other materials during the manufacturing process. The Masterbatch industry in the UK is estimated to have a turnover of around £200 million.
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 %.
At UEE we manufacture advanced lines for all kinds of filler masterbatch. We design the extruders for filler masterbatch, according to the output, formula and final application as your request.
Please contact us, should you wish to discuss your masterbatch line needs and we will happily advise on the best possible machinery to deliver this.
