Introduction
In high-filler formulations, dispersants play a crucial role. They not only influence the dispersion uniformity of pigments and fillers, but also directly dictate processing performance, surface quality, and production efficiency. Below are our empirical test results for dispersants across various material systems, providing objective data and visual comparisons to assist you in selecting the optimal formulation.
