Mica is already being used successfully as a sound insulation additive in the transport sector, automobile industry and construction:
- Plastic housings for tools
- Sound-absorbent coatings or components in cars, trains or air planes
- Bitumen tiles or films
- Pipe insulation for sound suppression
When these products also need to be flame retardant, expandable graphite is suited as an additional additive. This results in the best possible combination of the sound insulation properties of mica with the halogen-free flame retardant properties of expandable graphite.
