Properties
Expanded mica has a lower insulation value (λ = 0.065–0.07 W/mK) than, for example, expanded volcanic perlite rocks that can be used for comparable applications. Due to the moderate insulating effect, larger insulation thicknesses are required. Its μ value is 3 to 4. Bituminated expanded mica is easy to compact, stable and retains volume. Due to its mineral origin, it is rot-proof, permeable to vapour diffusion, resistant to pests and non-flammable. Bloated mica can absorb larger amounts of water without changing its shape.
Expanded
mica is supplied in bulk.
The
most important area of application of expanded mica is refractory insulation in industrial applications. However, expanded mica is also used as a bulk insulation material for cavity fills between upholstery timbers. In addition, bitumen-like expanded mica can be used as a levelling fill under floating structures (screeds). Furthermore, expanded mica can also be used as an additive in concrete or plaster.
