Vermiculite is used as a carrier and bulking agent across many industries, thanks to many of its renowned properties, including:

High Absorbency

Expanded vermiculite is highly absorbent and capable of wicking fluid and attracting nutrients.

Light Weight

Vermiculite adds mass to a product without the heavy weight of many other bulking agents. This increases ease of application and can help save on transportation and labor costs.


It won’t rot, mold, or decay—essential requirements for carrier and bulking agents.
