Application

Expanded vermiculite is a lightweight, highly absorbent, and fire-resistant mineral widely used:

1: Construction

Acts as a lightweight aggregate in concrete, plaster, and fireproofing compounds.
Commonly used in roof and floor screeds, chimney linings, and insulation panels.
Provides thermal insulation and sound absorption.
2: Fireproofing and Insulation

Used in passive fire protection systems.
Fills fire doors, safes, and panels for high-temperature insulation.
Excellent for pipe lagging and cavity wall insulation.
3: Packaging and Absorbent Material

Serves as a lightweight, shock-absorbent filler for fragile items in transport.
Absorbs oils, chemicals, and hazardous spills in industrial environments.
4: Animal Feed and Carrier

Used as a carrier for animal feed additives, pesticides, and fertilizers.
Non-toxic and chemically inert, making it safe for agricultural applications.
5: Industrial and Chemical Uses

Acts as a filler in paints, coatings, plastics, and refractories.
Used in brake linings and gaskets due to its stability under high temperatures.

Horticulture Vermiculite:

Rooting cuttings: Professional nurserymen use vermiculite for the insertion of cuttings. Use directly as poured from the bag, water thoroughly and insert cuttings.Soil amending:
Where native soil is heavy (clay), mixing vermiculite is recommended to increase air space. Where the soil is sandy, mixing vermiculite is also recommended, Its water retention allows the amended soil to hold more water, decreases drought stress, and maintains vigorous plant growth.

Seed Germination:
Many commercial growers use vermiculite to cover sown seeds. Since water and relative humidity play an important role in the
germination process, seed planted with vermiculite will be protected against fast drying conditions.
Soil mixes:
When mixed with soil or soilless media, vermiculite promotes aeration helping young plants to take hold easily. Seedlings will
also be easier to remove with less danger of breaking off hair roots. Its high water retention will also decrease the irrigation
frequency by naturally regulating water availability in the seed tray.

Storing bulbs and root crops:
Always allow moist bulbs to dry a few hours and then place in cartons and cover with vermiculite to absorb any excess moisture. Since it absorbs moisture, vermiculite helps protect your bulbs against mildew. The insulating properties protects your bulbs from temperature changes.
