Abstract:
Dispersion and dilution require careful consideration when using a masterbatch. These two terms are often confused with one another. For instance, when using a masterbatch there are the two key properties that require careful consideration. the DISPERSION of pigment (or additives) within the masterbatch; the DILUTION of the masterbatch into the fabricator's polymer during use.
What is dispersion?
Dispersion is a measure, at both the microscopic and macroscopic levels, of how a pigment, filler or additive is completely distributed throughout a polymer matrix. It is probably one of the most fundamentally important properties of any masterbatch.
What is dilution?
Dilution is a measure of how well and how easily a masterbatch mixes with a fabricator's polymer. Thus, a masterbatch exhibiting good dilution properties will produce processed articles (film, bags, pipe, sheet, etc.) showing excellent distribution of the masterbatch within the fabricator's diluting polymer. Conversely, a poorly diluted masterbatch will produce processed articles showing surface defects (lumps, voids), inconsistent color and/or opacity, streaking and inferior physical performance.
