Applications

SHAWATEC® vermiculite is available in crude or exfoliated products. Insulating material, SHAWATEC® vermiculite is fireproof, lightweight, chemically inert and non-toxic. These characteristics added to its high cationic exchange capacity and excellent absorbency make it a perfect material to use in a wide range of applications :

  • Agriculture
  • Animal feed
  • Fire protection coatings
  • Foundry
  • Friction products
  • Hazardous waste absorption
  • Horticulture
  • Insulating boards
  • Lightweight concrete
  • Packaging
  • Plasters
  • Thermal and acoustic insulation
Fire protection coatings
