Company Profile

Yamaguchi Mica Co., Ltd.

Yamaguchi Mica Co., Ltd. (formerly Yamaguchi Mica Industrial) is a specialist mica-powder manufacturer. Using in-house-developed grinding equipment and a proprietary wet-grinding and classification process, it takes high-crystallinity Indian muscovite as feedstock and, through refining and iron removal, produces smooth, thin, high-aspect-ratio flake mica powder. Mica (CAS 12001-26-2) is a layered silicate; as a functional filler it reduces molding shrinkage, improves dimensional precision and rigidity, and enhances damping, sound insulation and barrier performance. The company also offers wet, media-ground, blended and dry-process products, and in sustainability and compliance holds an EcoVadis silver medal and Halal certification, and belongs to the UN Global Compact and the Responsible Mica Initiative (RMI).
