Under the principle of coloring the polymer, we mean the following:
-a customer buys a colored material
-a customer buys a “dye”
-colorless dye material and mixed.
Two concepts coloring material.
-“Natural” polymer;
-Coating the entire polymer batch;
-Preparation of the masterbatch of the party;
-Polymer processing, painted in the factory;
Recycling “natural” with the addition of the polymer masterbatch (coloring at the time of processing)
-For sootvetstvuyushaya manner dyed end-products:
-the polymer should have a corresponding background color and be thermally stable in a wide range of process parameters
-bright background color of the polymer is advantageous for dyeing, but the presence of such color is not obligatory
requires an appropriate dye
-It requires appropriate size for feed pellets natural polymer and the concentrated dye
