Burnt Talc
Burnt Talc is the pure white talc powder prepared by burning and pulverizing.
It is processed under strict quality control with improved electrical insulation, thermal stability, adhesion, and weather resistance.
Because of the excellent features of the product, it is used in electronic material and related fields.

Surface treated Talc
The resin affinity, dispersibility, and water repellency of talc can be improved by chemically and physically coupling the surface of talc with a chemical treating agent, such as a silane.
Nippon Talc applies surface treatment know-how developed in house to in-house equipment and conduct manufacturing activities, ranging from the small-scale production of prototypes to the mass production of products.
Various types of talc are available for bases, such as NANO ACE , ultrafine-powder talc, fine-power talc, general-purpose talc, and burnt talc. Furthermore, treatment agents in a wide range, such as epoxy, amino-based, silicon-based, and fatty acid-based agents, are available.
