Color Standards for Plastics — Plastic Colorants and Color Concentrates

Posted on Sep 02, 2022 by HunterLab

Plastic is a widespread medium for various applications, from children’s toys to kitchen tools. Coloring plastics can take on many different forms, and it’s vital to meet industry standards for safety and performance. At HunterLab, our spectrophotometers help plastic manufacturers create ideal color concentrates for their products.

ASTM Color Standards for Plastic

The American Society for Testing and Materials (ASTM) provides a series of standards for plastic production. While plastic is easy to mold and ideal for many applications, it’s a synthetic material that may be poorly made or unsafe for use.

ASTM standards provide rules and guidance for plastic production to ensure products last and stay safe throughout their lifespan. The organization’s website offers extensive documentation for you to follow these standards in your operation. Criteria include descriptions like:

  • Specifications for materials
  • Testing methods
  • Production procedures

Color is an essential feature of plastic standards because plastic colorants can affect the quality of the material. Plastic producers use color charts to compare their colors, and the best way to handle this comparison is with color measuring devices. Machines like spectrophotometers quantify color based on the light it absorbs and reflects, so manufacturers can create a match to a color on the chart.

What Are Color Concentrates for Plastics?

Color concentrates are plastic colorants in a pellet or grain that manufacturers form into plastic. Rather than adding a colored layer to the outside of a plastic product, concentrates make up the product.

To create a concentrate, a pigment is mixed with a polymer or carrier resin. For concentrates to work, the polymer must work with the base resin that the concentrate mixes with. The challenging aspect of concentrates is the lack of a universal polymer. Developers must identify the best polymer and base resin for production.

Color Standards for Plastics — Plastic Colorants and Color Concentrates

Posted on Sep 02, 2022 by HunterLab

El plástico es un medio muy extendido para diversas aplicaciones, desde juguetes infantiles hasta utensilios de cocina. La coloración de plásticos puede adoptar muchas formas diferentes, y es vital cumplir las normas industriales de seguridad y rendimiento. En HunterLab, nuestros espectrofotómetros ayudan a los fabricantes de plásticos a crear concentrados de color ideales para sus productos.

Normas ASTM de color para plásticos

La Sociedad Americana de Pruebas y Materiales (ASTM) establece una serie de normas para la producción de plástico. Aunque el plástico es fácil de moldear e ideal para muchas aplicaciones, es un material sintético que puede estar mal hecho o ser inseguro para su uso.

Las normas ASTM proporcionan reglas y directrices para la producción de plásticos con el fin de garantizar que los productos duren y sean seguros durante toda su vida útil. El sitio web de la organización ofrece amplia documentación para que pueda seguir estas normas en sus operaciones. Los criterios incluyen descripciones como:

  • Especificaciones de los materiales
  • Métodos de ensayo
  • Procedimientos de producción

El color es una característica esencial de las normas sobre plásticos porque los colorantes de los plásticos pueden afectar a la calidad del material. Los fabricantes de plásticos utilizan cartas de colores para comparar sus colores, y la mejor forma de realizar esta comparación es con dispositivos de medición del color. Máquinas como los espectrofotómetros cuantifican el color en función de la luz que absorbe y refleja, de modo que los fabricantes pueden crear una correspondencia con un color de la carta.

¿Qué son los concentrados de color para plásticos?

Los concentrados de color son colorantes plásticos en gránulos o granos que los fabricantes forman en el plástico. En lugar de añadir una capa de color al exterior de un producto de plástico, los concentrados conforman el producto.

Para crear un concentrado, se mezcla un pigmento con un polímero o resina portadora. Para que los concentrados funcionen, el polímero debe funcionar con la resina base con la que se mezcla el concentrado. El reto de los concentrados es la falta de un polímero universal. Los desarrolladores deben identificar el mejor polímero y resina base para la producción.
