As with many other high performance engineering polymers, polyamide resins require pigments with a bluish white undertone, a hydrophobic surface, excellent mechanical, thermal and rheological performance stability, and the lowest possible amount of metallic impurities, such as iron.
DuPont TiO2 products having these desired attributes are Ti-Pure® R-103, R-104, and R-105. Product selection depends on the desired end use color, compound formula and processing methods and equipment. For automotive under-the-hood applications, Ti-Pure® R-103, R-105, and R-960 are suitable because of their excellent thermal resistivity. For durable applications, Ti-Pure® R-105 and R-960 will deliver excellent performance.
