The UK leader in Stud Welding and Refractory products
Exfoliated Vermiculite is a lightweight, expanded mineral widely used for thermal insulation, refractory applications and industrial processing. Produced by heating natural vermiculite to create low-density granules with excellent insulating properties, it provides an efficient solution for reducing heat transfer while maintaining excellent resistance to high temperatures.
Available in superfine, fine, medium and large particle grades, Exfoliated Vermiculite is suitable for a wide range of industrial, horticultural and construction applications. Its low density, excellent thermal insulation and versatile particle sizing make it an ideal material for insulation fills, lightweight refractory products and specialist manufacturing processes.
Exfoliated Vermiculite offers an excellent combination of lightweight performance, thermal insulation and versatility across a broad range of industrial applications.
