Talc Powder

Overview

Talc is the softest mineral on the Mohs scale, which is why it can be loaded into a polymer or a coating without wearing screws, dies or calender rolls. Its layered crystal structure orients during processing and raises flexural modulus, heat deflection temperature and dimensional stability, while its chemical inertness keeps formulations stable. We grind talc from the Haicheng talc belt from 325 to 3000 mesh. Our talc standard TDHX-TALC-2023-07 specifies SiO₂ 20–65%, moisture ≤1% and whiteness 70–97%; individual grades are tighter than that — for example one TD-8 grade runs SiO₂ 30–50% at whiteness 87–93 — so tell us the application and we will quote the closest grade or adjust the chemistry to your target.
