Adding these additives directly can be challenging in terms of dispersion and efficiency, so they are often incorporated in the form of a masterbatch. Let’s delve into the fundamentals of functional masterbatch together.
Functional Masterbatch Particle Size: These are granular solids with particle sizes ranging from 0.1 to 3mm. When the particle size is as small as 0.1mm (100μm), it’s considered fine powder. Particles within the range of 1-10μm are categorized as fine powder, while those between 0.1-1μm are termed ultrafine powder. On the other hand, particle sizes exceeding 3mm form solid blocks. Generally, smaller particle sizes result in denser mixtures. However, smaller solid particles are more prone to adsorption and aggregation, making it challenging to disperse them in plastic melt.
Particle Size Distribution of Functional Masterbatch: Powder with a broad particle size distribution is more densely packed compared to powders with narrow distributions. Small particles can penetrate the gaps between larger ones, making it difficult to blend two powders with significant differences in particle size.
