Mica Paper 1000°C

Mica Paper, up to 1,000 °C

Final Advanced Materials supplies various types of products comprised of at least 90 % muscovite mica or phlogopite mica (magnesium silico-aluminate). The term “mica” describes a family of minerals which are characterized by a laminar flaked structure. The particular thermal and dielectric properties of these minerals make them suitable for numerous applications. Easy to machine and bond with adhesives, they represent an easy-to-use high-temperature solution.

Phlogopite mica paper is comprised of 90 % mica impregnated with a specific high-temperature-resistant binder, and reinforced by glass fibre applied to one side. When this paper is exposed to high temperatures, its resin content breaks down, without impairing the high-temperature electrical insulating properties of mica. Its dielectric strength remains constant up to 380 °C, then decreases progressively. Moreover, mica paper is chemically neutral, non-toxic and entirely halogen-free. It shows excellent resistance to water, acids (excluding sulphuric acid), bases, mineral oils and solvents. The mineral phlogopite shows exceptional flame-resistance properties, and can easily accommodate peak temperatures of up to 1,000 °C.

Applications of Mica Phlogopite Paper 

• Burner gaskets
• Exhaust manifold gaskets
• Heat-exchanger gaskets
• Thermal insulation
• Electrical insulation

Technical Data of Mica Phlogopite Paper

In practice, tape is applied with the mica side facing the conductor in one or more layers, with overlaps ranging from 20 to 50 %.
