is a hydrated alumina silicate mineral, one type of mineral fiber, which is formed from aluminum oxide compound Al2O3 and silicon dioxide compound SiO2. Physically, Aluminum Silicate in the form of ultrafine powder/fine powder that is white and soft/soft to the touch, has high heat resistance and has very good electrical insulation/insulator properties, so that Aluminum Silicate is widely used as a filler in the Cable Industry and electronic components. In addition, ultrafine Aluminum Silicate powder also has high dispersion characteristics when dissolved in liquid solvents, both water-based solvents and solvent-based solvents, so that Aluminum Silicate is also widely used in the Paint & Coating Industry.
