One mighty mineral. Endless possibilities.

Insulation

As a loose-fill, low-density insulator, Silbrico Perlite is extremely efficient and ideal for filling odd-shaped spaces. Its natural properties of being lightweight, insulating, fire retardant, noise reducing, durable, inorganic and non-combustible make it the preferred choice for multiple insulation applications.

Uses

Ladle covers

Riser insulation

Lightweight castables

Insulation applications

Sound insulation

Cryogenics

High-temperature insulation

Particle sizes range from approximately
1 to 2,400 microns

This ultra-fine perlite is similar in size to microsphere perlite but is made by milling and classifying expanded perlite under our stringent quality-controlled conditions to create particles with jagged interlocking structures. Of course, with our Silbrico standards, consistency is always guaranteed. Our product line for this grade of perlite is Sil-Kleer.

At Silbrico, we refer to these industrial perlite grades as macroparticles. Coarser grades are clusters of glass bubbles containing a multi-cellular core, offering many industrial benefits like being lightweight and insulating. We apply non-flammable water repellent treatment to certain grades, which significantly improves the water repellent properties of perlite. Ryolex is our line of macroparticles.
