In special inks such as heat-set and moisture-set inks, talcum powder can help regulate the drying speed and ink layer stability, thus avoiding printing defects.

The layered structure of talcum powder endows it with lubricity, which can reduce the interaction force between ink particles, make ink coating more uniform, reduce sedimentation, and accelerate the drying process. ‌

Talc powder is primarily used as an inorganic filler in copper clad laminates (CCL) to enhance their performance. It belongs to the common category of fillers alongside materials such as silica micro-powder and aluminum hydroxide, and can assist in adjusting the dielectric constant, thermal expansion coefficient, and mechanical strength of CCL. Tianze talc powder is a crucial component in supply chain systems for high-frequency, high-speed CCL, PCBs, AI computing centers, and more.
