VERMICULITE - TERMIKAL

Uses of Expanded Vermiculite in Industry and Construction

Thanks to the unique properties of expanded vermiculite, it can be used in many applications in the fields of construction and industry.

Distinctive properties of the material:

  • Characteristic golden-gray color
  • Ultra-light bulk density
  • Accordion-like spongy structure
  • Fire-resistant and withstands extreme temperatures
  • High thermal and acoustic insulation capacity
  • High contact surface area
  • Liquid absorption capacity
  • Unique chemical and physical composition
  • Cation exchange capacity
  • Natural material free of chemicals

Vermiculite in the field of construction:

  • As loose-fill insulation for thermal, acoustic, and fire resistance in voids between walls or on tiled roofs
  • As a lining and coating material for transporting hazardous chemicals such as hospital waste
  • For preparing lightweight clay and concrete with thermal and acoustic insulation properties, and high fire resistance
  • With the addition of cementitious materials, it can be sprayed on steel structures for thermal and acoustic insulation

Vermiculite in the field of industry:

  • Floating insulation material in the metal and galvanizing industry
  • Central component in manufacturing brake pads for vehicles
  • Material for absorbing liquids and chemical solutions
  • Fire-resistant lining material for transporting fragile hazardous materials, hazardous chemicals, and nuclear hospital waste
  • Manufacturing fire-resistant boards
  • Fire-resistant, lightweight material used in manufacturing fireproof safes

It also has various other uses in the fields of decoration, pest-proof protective lining, absorbing bedding for valuable animals, and storing flower bulbs…
