Vermiculite

SPV Copr. VermiculiteWhat is Vermiculite?

Vermiculite is a hydrated magnesium aluminum sheet silicate mineral closely related to mica, and has all of the thermal and chemical resistance mica is known for. When subjected to heat, vermiculite expands and forms particles that are revered for being:

  • Lightweight
  • Incombustible
  • Compressible
  • Highly absorbent, soaking up to three times its volume in water
  • Non-reactive
  • Highly effective in cation exchange capacity

Vermiculite is found all over the world, including Australia, Brazil, Bulgaria, Kenya, Russia, South Africa, Uganda, USA and Zimbabwe. Speciality Vermiculite mines and processes vermiculite concentrate in facilities located in Enoree, South Carolina. Vermiculite is mined using open cast mining techniques where the ore is separated from other minerals and then screened or classified into several basic particle sizes.

How is Vermiculite Used?

Vermiculite’s water-wicking, lightweight, and thermal-resistant properties make it ideal for many applications and products, including:

Horticulture

Vermiculite acts as a magnet for nutrients like potassium, calcium, and magnesium, making it a valuable and time-saving addition to passive hydroponics systems. Vermiculite will slowly re-release valuable nutrients back into the soil, adding to the growing cycle.

Packaging Materials

Exfoliated vermiculite is easily poured around irregularly shaped objects and provides a cushion against shock during handling and transportation, often in the pharmaceutical and chemical industries.

Carrier and Bulking Agents

Vermiculite is lightweight, making it ideal for bulking products without adding a significant amount of weight.

Agriculture

Vermiculite’s high cation exchange capacity enables it to hold onto added nutrients to feed plants, cuttings, and seeds, allowing for faster and more successful growth. It can also enhance animals’ food to create the most nutrient-dense product.

Fire protection and thermal insulation

Vermiculite is thermal-resistant, slowing down the burning process for materials enhanced with it, like ceiling tiles and drywall.

Construction and Concrete

Lightweight, fire-resistant, and insulating construction materials are produced when Vermiculite is used as an aggregate.

Automotive

Finer grades of exfoliated Vermiculite are used in friction linings for automobiles because of its thermal resistance, shape, and surface characteristics.

Swim Pool Liners

Vermiculite is used to create a lightweight cement for a softer, more resilient pool floor for vinyl-lined pools
