It begins with mining of mica and ends with a wide range
of special mica tapes and components.
The term "mica" is used for a group of minerals that show perfect cleavage.
Mineralogically speaking, they are sheets of silicate. The name comes from
the Latin word micare, meaning to shine, in reference to the
brilliant appearance of this material.

Von Roll's commitment to mica starts with mining, followed by the very
specialized field of producing paper from a mineral and finishing with
the production of special mica tapes as well as mica ancillary parts.

Von Roll uses two types of mica, phlogopite and muscovite, for a variety
of applications and depending on the needed thermal and electrical
characteristic, mainly in:

Electrical and thermal insulation of electrical machines
Thermal insulation of equipment that is subject to extremely high temperatures,
such as induction ovens Insulation of cable for fire resistance

Examples of our product range include:

Mica paper from Samica® and Mica Mat®
VPI (vacuum pressure impregnation) main wall tapes with Samicapor®, Sisapor®, and Mica Mat®
Resin-Rich tapes with Samicatherm®
Conductor insulation with Samicafilm®
Induction oven insulation with Miglasil®
Miscellaneous parts such as collector rings, mica tubes, and mica sheets.
