Because vermiculite platelets are inorganic, vermiculite can be used as a high-temperature coating, binder, or filler in construction materials, gaskets, specialty papers, and high-temperature textiles
It can impart fire-resistance and upgrade the service temperature of the end product.
Coatings of vermiculite on fiberglass textiles have been shown to increase the service temperatures up to 1100C. These materials have found use in applications including safety fabrics, safety clothing, and thermal insulation.
Finder grades of exfoliated vermiculite are used in friction linings, primarily for the automotive market. It is used for this purpose because of its thermal resistance, ease of adding to other raw materials, and its shape and surface characteristics.
Finer grades of vermiculite are used in the production of insulation, often mixed with sodium or potassium silicate.
Vermiculite concentrate exfoliates immediately when poured onto hot metal to form an insulating layer that keeps the material hotter longer.
Vermiculite is used as an additive in Portland cement and used as a sealant in underground mines to prevent the ingress of methane, which might explode.
Finely ground vermiculite is added to improve their flame retardancy and enhance performance in areas where there is an excessive amount of ultraviolet light.
Calcium aluminate cements and exfoliated vermiculite can be combined to produce refractory concretes and mortars.
Vermiculite dispersions, like MicroLite, are used in high-temperature coatings or binders for construction materials.
Vermiculite concentrate is used as a “lost circulation material” in drilling muds to prevent downhole pressure losses during well drilling and completion activities.
MicroLite coatings containing vermiculite are made from dispersions after the mineral has been finely delaminated, either chemically or physically. Vermiculite dispersions are used in high-temperature coatings or binders for:
Construction materials
Gaskets
Weld curtains
Specialty papers/textiles
Oxidation resistant coatings on carbon composites
As barrier coatings for films
When combined with other fillers, milled exfoliated vermiculite and a ‘paint type’ binder can be used as a wet spray-applied anti-drumming compound. These products are used extensively to dampen the vibration of architectural panels, like those used in curtain wall construction or as claddings in railway stations and tunnels.
An Insulating Blanket that Reduces Heat Loss
Molten steelMolten Steel Insulation vermiculite expands when placed as a cover on molten metal, creating an insulating blanket, reducing heat loss. Vermiculite is chemically inert, inorganic, and will not create smoke when heated. Molten Steel Insulation features specially sized and packaged vermiculite made just for use by the molten metals industry.
It’s Easy and Consistent—the Ideal Combination
Simply throw the bag onto the metal, and Metal Steel Insulation expands and spreads upon contact to provide insulating coverage. Because it is coarser when it expands, Molten Steel Insulation is less dusty than finer powder insulations.
You’ll know what to expect each time you use it; it is uniform in size for even flow characteristics and has repeatable chemistry from batch to batch.
And you don’t have to think twice about the bag—it is made of polyethylene and disintegrates upon contact with the molten metal.
