This fire-proof Mica paper is made by bonding phlogopite, muscovite mica paper with supporting materials. This results in a material that is very flexible and easy to wind on to narrow conductors.
It is suitable to use as a heat resistant barrier for fire-proof cables, and other industrial high temperature insulation applications.
