SIL-CELL® Perlite Microsphere: Lightweight and Efficient
CMMP distributes the SIL-CELL® perlite microsphere, a technical material developed by Silbrico Corporation, a global expert in expanded perlite.
This perlite microsphere is designed to lighten, reinforce, and stabilize your formulations without altering their chemical or mechanical properties. It is aimed at demanding professionals seeking a reliable, durable, and stable solution for a wide range of industrial applications.
SIL-CELL® particles are spherical, hollow, siliceous, inorganic, and non-toxic. Their structure guarantees both lightness and compressive strength. SIL-CELL® perlite is pH-neutral, avoiding any unwanted chemical reactions in sensitive formulations.
Its microspherical format ensures homogeneous dispersion, allowing for easy handling and precise dosing in your blends. Thanks to its low density, it can effectively replace other mineral fillers while reducing the overall weight of the final product. Its multicellular structure also ensures excellent tensile strength and surface performance in composites.
What are the applications of SIL-CELL® perlite?
The SIL-CELL® perlite microsphere is ideal for many technical applications in the materials and composites industries.
It is used in lightweight concretes, technical coatings, exterior finishes, decorative paints, and resin-based formulations. In these products, it helps reduce weight, improve stability, and maintain expected mechanical performance. It is also found in asphalt and road binders, where its lightness and thermal resistance are key assets.
In composites, SIL-CELL® acts as a functional filler while ensuring good inter-material adhesion. It can be surface-treated to enhance bonding with organic or mineral matrices.
The microsphere is also used in industrial adhesives, automotive body fillers, repair compounds, and decorative stuccos. Its lightness makes it suitable for ready-mix plasters, insulation products, cosmetics, and advanced resins.
Thanks to its versatility, it can be used in aqueous formulations, dry matrices, or thermosetting systems. In every case, it contributes to optimizing density, improving texture, reducing costs, and enhancing final performance.
Technical advantages of SIL-CELL® perlite
SIL-CELL® Perlite stands out for its stable mineral composition and unique multicellular structure, ideal for technical applications. It primarily contains silica, alumina, magnesia, lime, titanium, and iron oxides.
These elements give it high chemical stability, with no reaction to binders, resins, or other sensitive components. It is pH-neutral, ensuring optimal compatibility with many environments, even in complex formulations.
Its hollow, multicellular structure provides high tensile strength at very low weight. This spherical geometry promotes homogeneous dispersion in mixtures, without clumping.
SIL-CELL® remains inert and non-toxic, making it safe for use in demanding or regulated environments.
Its low bulk density makes it an excellent lightweight filler that does not compromise the structural integrity of the final product. It retains its structural integrity under varying conditions of temperature, pressure, and humidity.
It meets the needs of manufacturers looking for a stable, lightweight, durable, and high-performance filler.

SIL-CELL® Perlite Microsphere: Lightweight and Efficient
Yes, GRANUTEC® vermiculite is highly suitable for lightweight, insulating, and fire-resistant concrete. Mixed with Portland cement and water, it forms a lighter and more thermally efficient concrete without compromising mechanical strength.
This concrete is used for roofing, slabs, screeds, or precast elements. It combines ease of handling, fire resistance and low thermal conductivity.
Formulations can be adjusted with or without resin depending on the project’s needs. Vermiculite acts as a technical aggregate that stabilizes the mix while reducing the weight of the finished product.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
Yes, GRANUTEC® vermiculite provides excellent thermal and acoustic insulation. Its expanded lamellar structure traps air, limiting heat and sound transmission.
It is commonly used in loose-fill insulation for cavity walls, attics, floors, doors, and partitions. It helps stabilize indoor temperature by reducing heat loss in winter and heat gain in summer.
It also absorbs airborne noise, making it useful in residential and industrial buildings. Easy to handle, it can be poured or blown into place depending on the site requirements.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
Yes, GRANUTEC® vermiculite is naturally non-combustible. It withstands temperatures up to 1100°C without degrading or releasing toxic fumes.
This property comes from its lamellar mineral structure and low thermal conductivity. It is widely used in passive fire protection systems, including sprayable coatings, prefabricated panels, fire doors, and fire-resistant plasters.
Vermiculite also plays a key role in refractory concrete formulations for high-temperature environments. Its dimensional and chemical stability ensures long-term fire resistance.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
Yes, SIL-CELL® has insulating properties. The porous, multicellular structure of the perlite microsphere gives it excellent thermal and acoustic performance.
It effectively reduces thermal conductivity in plaster, mortar, or coating formulations by limiting thermal bridging. This makes it an ideal filler for insulating coatings, lightweight thermal concretes, or composite insulation panels.
In acoustics, it can also help dampen noise and reduce reverberation when incorporated into sound-absorbing materials. These properties vary depending on the particle size used, the incorporation rate, and the nature of the final substrate.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
No, the SIL-CELL® perlite microsphere is a naturally safe material. It is inert, inorganic, and has no known toxicity. It contains no solvents, volatile organic compounds (VOCs), or harsh chemical additives.
It is chemically neutral, meaning it does not interact with other components in your formulations, even the most sensitive ones. Its neutral pH ensures optimal compatibility with most organic, mineral, or polymer matrices.
No harmful emissions are generated during storage, handling, or integration. It can be used in demanding environments, including food (excluding direct contact), cosmetics, or medical applications, depending on the context.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
Yes. The SIL-CELL® microsphere integrates seamlessly into thermosetting resins (epoxy, polyester, polyurethane) as well as thermoplastics.
It does not chemically react with organic or mineral binders, ensuring long-term stability. Its neutral pH and inert nature guarantee no interaction with additives or curing agents.
It can be used as-is or surface-treated (with coupling agents) to enhance adhesion in complex matrices. Its behavior remains stable even under thermal cycling or mechanical stress.
SIL-CELL® Perlite Microsphere: Lightweight and Efficient
The SIL-CELL® microsphere stands out due to its fine particle size, consistent spherical shape, and unique multicellular structure. Unlike conventional expanded perlite, it is lighter, more uniform, and better controlled in terms of density and size.
Its internal structure, made of closed cells, provides higher mechanical resistance to compression and tension. This regular spherical shape improves flowability in mixtures, makes dosing easier, and reduces the risk of clumping.
As a result, it delivers superior performance in technical formulations, especially when homogeneous dispersion is critical.

SIL-CELL® Perlite Microsphere: Lightweight and Efficient
A perlite microsphere is a small, hollow, spherical particle that is extremely lightweight and produced by the thermal expansion of volcanic perlite. When heated to around 1200 °C, perlite expands like popcorn, forming a porous, multicellular structure.
This process creates a siliceous particle that is stable, naturally inorganic, inert, non-toxic, and pH-neutral.
