DYE CONCENTRATION PRECISELY TO YOUR SPECIFICATIONSTreffert specialises in creating color masterbatches that exactly conform to stated specifications. We achieve this by using exactly the plastic that will later be dyed by the processor as our carrier material. The dye concentrates make it possible to economically self-dye in most plastics processing procedures thanks to their great flexibility in formulating the recipes and provides clean, smooth processing. Dye formulas that have been created can be reproduced even years later with absolute fidelity to the original. Just ask about our color masterbatch es online or contact one of our application engineers in order to discuss the requirements for your product with you in your offices.
Process for manufacturing a color masterbatch
A color masterbatch, or color concentrate, is a granule used for coloring thermoplastics. It consists of one or more colorants and a polymer-specific carrier resin. The composition of a color masterbatch is called its recipe.
Colorants are classified into several categories: organic dyes, organic pigments and inorganic pigments.
Dyes are soluble in plastics and can therefore be used for transparent coloration. Pigments remain in their original particle form inside the plastic and need to be dispersed within the plastic.
The recipe for a specific color masterbatch is developed in our laboratory based on a customer’s requirements.
A color masterbatch may contain up to 60% colorant. In the subsequent production process, the colorant is introduced into the melted plastic.
