- Market Applications
Industrial (Packaging, Absorbent):; Vermiculite is used as a lightweight filler, liquid absorbent for dangerous goods and lab packing and as a liquid waste solidification agent.; Construction (Insulation, Concrete Aggregate):; Vermiculite is ideal as a pool base under vinyl lined pools, chimney insulation mix, light weight aggregate in plaster and concrete, attic insulation, aggregate in spray-on fireproofing and as a masonry fill insulation.; Horticultural (Lt. Wt. Soil Amendment, Seed Topping):; Light weight Vermiculite provides aeration and moisture retention.; It also possesses cation exchange properties, thus it can hold available to the growing plant ammonium, potassium, calcium and magnesium.
