2. What is the advantage of using masterbatch (MB)?
- Low stock holding compared with pre-compounded materials.
- Optimum dispersion of pigments/additives.
- Dust free, no health and safety risks in comparison to undispersed fine powder pigments or additives.
- Elimination of 'trial and error' development or formulation work, as this done by the masterbatch supplier who takes responsibility for color and consistency.
- Reduction in purging/cleaning costs.
- Compared to compounds the masterbatch approach open to variable range of colors and other properties. The alternatives to using masterbatches are buying a fully compounded material (which is more expensive and less open to e.g. color variability of the product), or compounding from raw materials on site (which is prone to issues with achieving full dispersion of the colorants and additives, and prone to preparing more material than what is used for the production run).
- The use of masterbatch allows the factory to keep stock of fewer grades of the polymer, and to buy cheaper natural polymer in bulk.
- The masterbatch can be fairly highly concentrated (in comparison with the target composition), with "let-down ratios"; e.g. one 25 kg bag can be used for a ton of natural polymer. The relatively dilute nature of masterbatch (in comparison with the raw additives) allows higher accuracy in dosing small amounts of expensive components.
- The compact nature of the grains of solid masterbatch eliminates problems with dust, otherwise inherent for fine-grained solid additives. Solid masterbatch are also solvent-free; therefore they tend to have longer shelf life as the solvent won't evaporate over time.
3. How masterbatch is made?
In simple terms, manufacture is a two-stage process: gathering ingredients and then mixing them together by applying heat and shear to produce a homogenized pellet. Generally high or low speed mixers are used to produce a pre-mix of the additives which is then compounded on roller mills, kneaders, single or twin screw extruders. Even distribution (dispersion) and development (breaking down) of the additives throughout the carrier are essential. This processing depends on several key elements: formulation, quality of raw materials, quality of mixing and compounding plant. Finally, the finished masterbatch is pelletized (die-face or strand cut or round).
4. What is most common carrier for masterbatch?
The carrier material of the masterbatch can better to be a specific polymer, identical or compatible with the natural polymer used (polymer-specific). E.g. LDPE, PP, PC, PET, polystyrene can be used for GPPS, ABS, SAN. When a carrier different than the base plastic is used, the carrier material may modify the resulting plastic's properties; where this could be important, the carrier resin has to be specified. The carrier material can be a universal carrier also like wax, EVA etc. However it is better to use a MB which has good compatibility with the customers. Universal masterbatch employs a carrier system that is capable of carrying the high quantities of additives necessary to deliver the end use properties required as well as affording the essential compatibility required across a broad range of polymers.
5. Does the masterbatches influence the property of products?
Some pigments have effect on flame resistance. If used for flame resistace, products should be mentioned as first the detailed applications. Also some additive masterbatch cannot add together in same layers of films since they have adverse effect while using in combination. So in all cases, it is better to consult our technical department for details.
6. Does the masterbatch need to be dried before use?
In general, it can be used directly except for
styrenic and polycondensation polymers like PET, PC and some special masterbatch mentioned, which should be dried according to common method and processing condition mentioned in TDS.
