Colouring materials in plastics - Determination of colour stability to heat during processing of colouring materials in plastics - Part 2: Determination by injection moulding

This document outlines the specific methodology for evaluating the thermal stability of plastic color materials during their processing stages. The focus lies on the second part of a broader series, which specifically employs injection molding techniques to assess how these coloring agents withstand heat under operational conditions. By utilizing this approach, manufacturers and quality control professionals can determine the performance characteristics of pigments and dyes within the complex environment of plastic manufacturing. The procedure ensures that materials maintain their integrity and desired color properties throughout the high-temperature phases of injection molding. This standardized test method provides a consistent framework for comparing the stability of various coloring formulations, thereby supporting the optimization of production processes and the assurance of final product quality. It serves as a technical guide for executing precise measurements and interpreting results related to thermal degradation in colored plastics.
