Designing Color Masterbatches to Meet the Demands of the Application

 

Papers # 2014 Chicago

Color masterbatches or concentrates have been in use with plastic pipes as a means of color coding for identification of pipes by application. The color masterbatch contains not only color pigment(s), but also other ingredients that are necessary to protect the pipe during production and assure long-term durability. This paper highlights the development and use of masterbatches for a composite piping system that has gained global acceptance in a wide variety of applications. The paper will present information on some of the parameters necessary in developing a color masterbatch and also highlight specific cases/success stories on use of the masterbatch in demanding composite piping applications.

In designing and installing a total piping system, there are many aspects to consider when one selects the various components that comprise the piping system. One aspect that has been successfully utilized in the plastics piping industry is the use of colorants to identify the targeted end-use application of the piping system. In general, this identification method has been globally accepted and has resulted in safe, quality plastic piping systems being installed and utilized throughout the world. In most countries that recognize the ISO application standards for PE piping systems, the requirement for materials is that a colored PE compound be utilized in the production of pipe and fittings. In some countries that recognize the ISO application standards and in countries that recognize the ASTM application standards for PE piping systems, the option to utilize either a colored PE compound or “salt and pepper” blending of a natural compound and its approved color masterbatch is available to the processor in the production of pipe or fittings.
