Technical Data Sheet



SW-MICANITE RIGID M & P sheets are specially developed for providing outstanding thermal and electrical insulation for various heating elements used in household and industrial appliances such as hair dryers, tumble dryers, strip heaters,… and for all other applications where excellent resistance to thermal, mechanical and electrical properties are required.

Fire resistance classification UL94 (94 V-0), BS 479 (class 1), NBN 21-203 (A1). NFF16-101/2 (M0 u. F0), IEC 60371-3-3 conformity.

Composition: SW-MICANITE RIGID M & P sheets consist of minimum 90% Muscovite alternatively Phlogopite impregnated with an outstanding high temperature resistant silicone resin.
Supply Form: Thickness: 0.10 – 1.90 mm ± 0.05 mm
Size: 1000 mm width, max. 2400 mm length ± 1.0 mm
Customized strips or punched parts according to customers’ drawings and/or requirements.
Processing: SW-MICANITE RIGID M & P sheets can be easily punched. Tools for punching precise parts should be provided with spring loaded hold-down plates.
“SSQ” Special
Surface Quality:

SW-MICANITE RIGID M & P “SSQ” is a rigid mica sheet (Muscovite alternatively Phlogopite) with a higher density, a higher flexural strength and a smoother surface (obtained by steel pressing). The “SSQ” quality is most suitable for punching highly detailed pieces or when imprinting is required.
