Product Overview

Mica is a naturally occurring group of silicate minerals characterised by their plate-like particle structure, excellent thermal stability and high aspect ratio. These unique properties make mica an effective functional mineral for improving mechanical reinforcement, dimensional stability, barrier performance and electrical insulation in numerous formulations.

Available in a range of particle sizes and grades, mica is widely used throughout coatings, plastics, rubber, construction materials, adhesives, sealants, ceramics and selected personal care applications. Its low abrasiveness, chemical inertness and excellent weather resistance help enhance product durability while maintaining consistent processing performance.
