Perlite Functional Fillers

Dicalite perlite functional fillers are a versatile family of mineral-based silicate products used in ceiling tiles, lightweight cement, insulating plasters and much more. Our perlite fillers will elevate your processes to new heights. including high surface area, permeability and reinforcement that has densities among the lowest of any of the mineral fillers.

Unlock the incredible potential of Dicalite Europe’s expanded perlite.

Discover a new era of efficiency and insulation for all your applications. Dicalite perlite functional fillers are a versatile family of mineral-based silicate products available throughout the world. A specialized Dicalite process incorporating expansion, selective milling, and sizing determines the particle shape of each filler product. A variety of flake or di-, tri-, and tetrahedral particle shapes are obtained by this exclusive process. These unique shapes provide numerous functions including high surface area, permeability and reinforcement and have densities among the lowest of any of the mineral fillers. In addition to superior spatial loading, this property affords customers the added bonus of density control in their finished products.


Worried about interference with product coloring? Don’t be! Dicalite perlite fillers are off-white and won’t compromise the vibrant hues of your formulation.

Incredible Density Control

Our perlite fillers boast one of the lowest densities among mineral fillers, giving you complete control over the density of your finished products.

Versatile Shapes

Thanks to an exclusive process, Dicalite perlite fillers come in a variety of flake or di-, tri-, and tetrahedral shapes. These shapes enhance their functions, such as high surface area, permeability, and reinforcement.


Ensures Fire Safety

Fire safety is a top priority in every building. The right sheet material is essential to make your construction fire-safe which includes fire-resistant and fire-retardant, fireproof or non-combustible. Perlite is an essential component in wall boards to reach this goal. After years of testing and cooperation between our company and our producers of fire retardant plates, we’ve developed a state of the art expanded perlite, both in coated and uncoated form, suitable for fire wall boards.

Fire retardant boards or plates are widely used in making buildings and tunnels fire proof that include systems in compartmentalization, floor finishes, smoke extraction ducts, structure protection, ventilation and much more!

Free From Organic Materials

This means that it boasts an incredibly low solubility in carbon tetrachloride, with only traces detected. In some applications where temperatures drop to mind-boggling lows, it’s crucial to have insulation that won’t degrade or react with the extreme conditions. That’s where expanded perlite steps in, ensuring optimum performance and safety. Not only does expanded perlite provide exceptional thermal insulation, but its chemical stability makes it an ideal choice for storing and transporting substances like liquid nitrogen and LNG.



Fully Safe to human health

One of the most remarkable advantages of expanded perlite is that it is fully safe to human health. Unlike other materials, it contains no crystalline silica, making it undetectable and non-hazardous. So, when it comes to protecting ourselves and the environment, expanded perlite is a clear winner with its exceptional insulating properties and health-friendly nature.

Very Low Moisture Content

With expanded perlite, you can ensure optimal insulation in your applications preventing any potential moisture-related issues. Its moisture-resistant properties keep your equipment safe and efficient. If you’re looking for a reliable and durable insulating material for your processes, expanded perlite is the way to go. Discover the countless advantages it offers in maintaining the integrity and performance of your equipment.

Very Low Thermal Conductivity

Did you know that expanded perlite is an incredible insulating material? One of its amazing benefits is its very low thermal conductivity, ranging from λs = 0.034 to 0.042 W/(m.K). This means it can effectively minimize heat transfer, keeping things cooler for longer periods. Whether it’s for industrial applications or scientific research, expanded perlite is the go-to choice for insulating systems.
