Superior Thermal Insulation Properties

Vermiculites low thermal conductivity (approx. 0.07 W/mK) makes it an exceptional choice for insulation in both commercial and residential buildings. Its expansion ratio allows for efficient bulk coverage, improving temperature regulation and energy efficiency while ensuring flame resistance and safety.

Versatile Horticultural Applications

This mineral is widely used to enhance soil quality due to its high water and nutrient retention capacity. Neutral pH and non-toxic properties make vermiculite raw suitable for a variety of plants, helping gardeners and commercial horticulturists improve growth and yield under eco-friendly conditions.

FAQs of Vermiculite Raw:

Q: How is vermiculite raw typically applied in construction and insulation?

A: Vermiculite raw is used as a loose-fill insulation in walls and attics, as well as in lightweight concrete and fireproofing materials. Its ability to expand, flame resistance, and low thermal conductivity ensure effective heat and fire insulation in buildings.

Q: What are the main benefits of using vermiculite in horticulture?

A: Vermiculite provides excellent water and nutrient retention, improving soil aeration and promoting healthier plant roots. Its neutral pH and non-toxic, odorless nature make it ideal for various crops and ornamental plants.

Q: When should vermiculite be stored and handled carefully?

A: Vermiculite should always be stored in a dry area to prevent moisture absorption, which can affect expansion properties and bulk density. Proper storage ensures the product retains its indefinite shelf life and maintains optimal performance in applications.

Q: Where is vermiculite most commonly sourced and exported from?

A: Vermiculite is commonly mined and processed in India, which is a prominent exporter, manufacturer, and supplier of industrial-grade vermiculite for global markets including construction and agriculture.

Q: What is the process for expanding vermiculite raw?

A: Vermiculite expands 820 times its original volume when rapidly heated above 800C. The water within its layered structure vaporizes, causing the mineral to exfoliate into lightweight, porous particles valued in thermal and horticultural use.

Q: How does vermiculite contribute to fireproofing and safety?

A: With a melting point over 1350C and excellent flame resistance, vermiculite is widely used as a fireproofing aggregate in plasters and insulation boards, enhancing building safety by acting as a barrier to heat and flames.

Q: What is the environmental impact of using vermiculite raw?

A: Vermiculite is an eco-friendly, naturally occurring mineral with high purity (90%). Its use supports sustainable agriculture and green building practices, with no toxicity or adverse environmental effects reported.
