Pigments are typically characterized by their dry, solid, and powdery nature. Conversely, masterbatches represent a more advanced form of colorant, being concentrated blends of pigments and additives within a base polymer.
While both pigments and masterbatches can be employed to color polymer-based products, manufacturers often lean towards the use of masterbatch for several compelling reasons.
Masterbatches, arriving in pellet form, are easier to store, transport, and operate. In contrast, pigments, being in powder form, pose challenges in terms of handling.
Masterbatches prove more adept at being handled during the manufacturing process compared to pigments.
Pigments, being airborne, carry a significant risk of contaminating the production line and adjacent lines during manufacturing.
Masterbatch is produced in a compatible matrix or base polymer, facilitating the dispersion of color in the final product, whereas pigments may not disperse as effectively.
Matching the base polymer used in the masterbatch to the final product polymer is a straightforward process, contributing to a smoother melting process.
Despite the lesser amount of pigment present in a masterbatch, it compensates by requiring more of the same product due to the challenges associated with poor dispersion in pigments.
Masterbatch surpasses pigments in providing excellent color consistency for products.
Masterbatch offers the flexibility of including additive components in predetermined ratios, leading to fewer variations during processing compared to pigments.
A masterbatch can integrate additive concentrates, providing beneficial properties such as flame retardancy, optical brightening, and UV stability. This, in turn, reduces the quantity of feed entering the processing line.
Masterbatches afford greater control over the opacity of colored products, allowing for fine-tuning to meet specific requirements.
In summary, the advantages of masterbatches over pigments are multifaceted. From ease of handling to enhanced color consistency, reduced contamination risk, and the incorporation of additive components, masterbatches offer a comprehensive solution.
