Red Macrolex Granules


Solvent dyes for engineering plastics

As early as the 1960s, Macrolex® dyes were developed for the special needs of plastics coloration. Process conditions for engineering plastics such as polystyrene, ABS, PC, PMMA, PA, and others are quite severe. The Macrolex® product range includes dyestuffs that are classified as disperse or solvent dyes. 

Macrolex® dyes are soluble in organic solvents, e.g., aromatics, esters, and chlorinated hydrocarbons. They are insoluble in water and dilute aqueous solutions of acetic acid or alcohol. Not being soluble in water and alcohol is important for use in consumer goods, food packaging, and children´s toys made of colored plastics, because the dye cannot bleed into the respective media.

Macrolex® dyes are available as:

  • Granulates (Gran)
  • Fine gran (FG)
  • Powder
