Buy best quality Vermiculite low price 48 INR / Kg at Wedge India. Vermiculite is a hydrous phyllosilicate mineral that undergoes significant expansion when heated. This expansion process, known as exfoliation, transforms the mineral into lightweight, fire-resistant, and highly absorbent particles. Due to its unique properties, vermiculite is used in a wide range of industrial, agricultural, and consumer applications.

 

Properties of Vermiculite

  • Thermal Insulation:

    • Low thermal conductivity makes it an excellent insulator.
    • Can withstand temperatures up to 1100°C.
  • Lightweight:

    • Expanded vermiculite is lightweight and easy to handle.
  • Fire Resistance:

    • Non-combustible and fire-resistant, suitable for fireproofing applications.
  • Absorbency:

    • High water retention capacity, beneficial for horticultural uses.
  • Chemical Stability:

    • Chemically inert and does not react with most chemicals.
  • Non-Toxic:

    • Safe for use in various applications, including those involving contact with plants and animals.

Applications of Vermiculite

  • Construction:

    • Insulation: Used as loose-fill insulation in attics and walls.
    • Fireproofing: Added to fireproof plaster and cement.
    • Lightweight Concrete: Mixed with cement to create lightweight, insulating concrete.
  • Industrial:

    • High-Temperature Insulation: Used in furnaces, kilns, and other high-temperature applications.
    • Packaging Material: Protects sensitive items during shipping.
    • Absorbents: Used to clean up spills of hazardous liquids.
  • Horticulture:

    • Soil Amendment: Improves soil aeration, moisture retention, and nutrient exchange.
    • Growing Medium: Used alone or mixed with other media for seed germination and plant growth.
  • Animal Husbandry:

    • Litter and Bedding: Used for its absorbent and insulating properties.
  • Automotive:

    • Brake Linings: Historically used in brake linings for its heat-resistant properties.
  • Agriculture:

    • Pesticide Carrier: Acts as a carrier for pesticides and herbicides, improving application efficiency.

Vermiculite in Insulation Applications

Vermiculite is particularly valued in insulation applications due to its low thermal conductivity, fire resistance, and lightweight nature.

Key Uses in Insulation

  • Loose-Fill Insulation:
    • Attics and Walls: Vermiculite can be poured into attics and wall cavities to provide thermal insulation. Its ability to flow into small spaces ensures thorough coverage.
  • High-Temperature Insulation:
    • Industrial Furnaces and Kilns: Vermiculite boards and blocks are used to insulate high-temperature industrial equipment. Its ability to withstand extreme temperatures makes it ideal for these applications.
  • Fireproofing:
    • Buildings: Vermiculite is used in fireproofing sprays and plasters, which are applied to structural steel to protect it from fire damage.
    • Fireplace Linings: Used in the construction of fireplace liners to improve safety and efficiency.

Technical Specifications for Vermiculite in Insulation

  • Thermal Conductivity: Approximately 0.048 W/m·K at 20°C
  • Maximum Service Temperature: Up to 1100°C
  • Density: 64 to 160 kg/m³ (depending on grade and application)
  • Fire Resistance: Non-combustible, meets various fire safety standards

Conclusion

Vermiculite is a versatile and valuable material with a wide range of applications across industries. Its unique properties, such as thermal insulation, fire resistance, and lightweight nature, make it particularly useful in construction, industrial, and horticultural settings. Whether used as loose-fill insulation, in high-temperature industrial applications, or as a soil amendment, vermiculite continues to be an essential material for improving safety, efficiency, and performance.
