Our Specialty Vermiculite brand is mined and processed in Enoree, South Carolina. We mine the vermiculite concentrate using an opencast mining technique where the ore is separated from other minerals and categorized into several particle sizes.

Our Specialty Vermiculite division is dedicated to making quality vermiculite products for a wide variety of customer needs and applications

Vermiculite is an ideal mineral that’s beneficial in many applications and products. It’s a hydrated magnesium aluminum sheet silicate mineral closely related to mica. When subjected to heat, vermiculite expands. The expanded particles are lightweight, and have thermal-resistant properties that make it ideal in these markets:

  • Agriculture
  • Automotive
  • Construction
  • Industrial
  • Masonry
  • Packaging
  • Specialty coatings
  • Swimming pools

Benefits of Vermiculite

Our vermiculite is produced in a variety of particle sizes and makes an excellent product in many applications. 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, and as barrier coatings for films. Some of the benefits include:

  • Compressible
  • Highly absorbent; soaks up to 3x its volume in water
  • High cation exchange capacity
  • Fireproof
  • Lightweight
