Organic Colorants for Plastics


Soluble organic dyes or pigments are chosen as a function of the type of plastic, application and compounding requirements. LANXESS can supply a wide color spectrum through its MACROLEX® dyes and its BAYPLAST® pigments.


LANXESS supplies a range of organic pigments and pigment microgranules with optimized dispersion properties for producing brilliant colors. These include products with outstanding weather stability, high tinting strength and good color retention. Soluble dyes for brilliant shades in high transparency and printy offer solutions for multiple applications. These are supplied as microgranules, too.

 

The product range includes the following:

 

 

 

1.)

BAYPLAST®

The organic pigments were developed especially for coloring plastics. However, they also display optimum dispersion characteristics in powder coatings. The BAYPLAST® products are characterized by their good color strength, excellent weather stability and lightfastness.

 

 

2.)

MACROLEX®

These soluble dyes available in a variety of colors are characterized by

  • high thermostability
  • high lightfastness and weather stability
  • high tinting strength
  • high brilliance

MACROLEX® dyes are ideally suited for the coloring of amorphous polymers such as PS, PC, ABS, PMMA and PET. Coloration can be varied from transparent to total coverage depending on the type of polymer and colorant combination (organic/inorganic pigments).

MACROLEX® dyes fulfill numerous legal requirements for use in food packaging and children’s toys.

MACROLEX® dyes are also available as microgranules, which offer our customers the following advantages over the conventional powder form:

 

  • low dusting
  • good flow and meterability
  • good dispersibility
  • good solubility
