Welcome to Specialty Vermiculite, a trusted source for minerals mined and processed in our South Carolina facility. On this website, you’ll find information about our products, including comprehensive guides, safety data sheets, and the benefits of using vermiculite whether you work in agriculture, construction, or a range of other industries.

What is Vermiculite

Vermiculite is a naturally-sourced mineral that’s as versatile as it is beneficial. It’s mined as a light-colored, hydrated magnesium-aluminum-iron silicate similar to mica. When heated, vermiculite expands into particles that possess a variety of benefits.

Benefits of Vermiculite

Once heated into its expanded form, vermiculite is revered for its valuable properties:

• Lightweight. Makes it easy to work with, without adding bulk to products.
• Durable. Will compress under pressure, making it flexible and long-lasting.
• Absorbent. Capable of retaining up to three times its volume in water.
• Cation Exchange Capacity (CEC). A high CEC means vermiculite can effectively hold and release essential nutrients.
• Resistant. Stands up to heat, flame, and chemicals.
• Sterile. This non-toxic mineral has a neutral pH.

Because of these benefits, vermiculite is a sought-after solution across industries looking for the following applications:

• Coatings: Create a lightweight, durable shield for strengthening and protecting materials exposed to intense heat and fire.
• Construction: Add durable strength and insulation where flexibility and fire resistance are required.
• Horticulture: Use in potting mixes to improve moisture retention and promote root growth.
• Packaging. Absorbent, incombustible material protects hazardous goods.

If you’re wondering where you can find a product with so many benefits, turn to Specialty Vermiculite.

Who We Are

Specialty Vermiculite is proud to be a direct source of mineral-based materials for industry leaders far and wide. We’re dedicated to delivering a top-tier product that’s tailored to customer requirements, so we take a hands-on approach to production. We mine and process our own minerals at our facility in Enoree, South Carolina, so we’re able to control every step of the process and ensure a consistent, high quality result.

We use advanced open-pit mining techniques to extract vermiculite. Once we carefully separate the ore from other minerals, we sort and categorize it based on its particle size. At our processing facility, we mill the vermiculite ore into three different grades:

• VCX203 (coarse)
• VCX204 (medium)
• VCX205 (fine)

You can choose to use any of these concentrated materials or have Specialty Vermiculite expand VCX203 and VCX204 for additional applications.
