Coloring of Plastics

Expert coverage of the state of the art in plastics coloring

This latest edition of Coloring of Plastics: Fundamentals offers an updated introduction to color as a science while also providing the foundation for many additional technological subjects. The basic families of colorants are described, along with their properties. The material examines how statistical analysis can improve the consistency of colored polymer production runs as well as the colorants used to match the color.

Other important topics covered in Coloring of Plastics: Fundamentals, Second Edition include:

• Environmental issues and the reuse of discarded material
• Potential problems with the interaction between colorants and other additives
• Measurement information and matching, visually and instrumentally
• Techniques for incorporating colorants into polymers as compounds or concentrates
• Special effect colorants

Polymer and colorant manufacturers, plastics compounders, and coating and synthetic fiber industries will acquire an enhanced appreciation of the complex technological issues a colorist must consider if a plastics coloring project is to succeed.

Instrumentelle Messung oder visueller Vergleich: Dieses Buch erläutert, wie man die Farbigkeit eines Plastikwerkstoffs beurteilen kann. Vorgestellt werden die wichtigsten Farbstofffamilien und ihre Einsatzgebiete. Natürlich kommen auch die Wirkung in der Umwelt und Aspekte des Recyclings zur Sprache. Interessant für den Praktiker ist die Diskussion der Wechselwirkungen zwischen Farbstoffen und anderen Additiven, etwa Weichmachern und Aufhellern.
