Mica is an incombustible material, capable of withstanding extreme temperatures ranging from 600°C to over 1000°C, depending on the grade. 

It is a naturally occurring mineral classified chemically as an aluminosilicate and structurally as a phyllosilicate. It consists of parallel sheets of silicate tetrahedra bonded to each side of an octahedral layer

Among the various types of mica, two hold significant industrial value: 

• Muscovite – The most common variety, this light-colored mica contains aluminum as the primary component of its octahedral layer. 
• Phlogopite – A darker-colored mica, characterized by magnesium as the dominant element in its octahedral layer.

At COGEBI Asia, we utilize both Muscovite and Phlogopite mica to produce materials in boards and tapes for use in various insulation applications.
