Mica: A temperature-resistant filler

Micas are natural phyllosilicates with a platelet-shaped structure. There are various types of mica. Light-coloured muscovite and dark-coloured phlogopite are use in industrial applications. They are exposed to various milling processes as well as separation processes with hydrocyclones and flotation before being milled and dried.

Furthermore we offer also the product range ASPOLIT, which consists of mixtures of 3/4 muscovite and 1/4 silica.

• laminar particles
• high aspect ratio (1:30)
