GRANUGLASS as an additive with a very wide range of applications

It is used in the construction industry, plastics, paints and coatings.It has the following properties: Glazed and closed surface, does not soak up water, has high mechanical strength, high abrasion resistance, excellent insulating properties.
Additional advantages: low-dust, non-flammable and environmentally friendly.
Stability of the material without time limitation - expanded perlite is 100% natural rock in terms of its chemical composition, which ensures its durability. Performance characteristics do not change over time. It will last for more than 50 years without losing its thermal insulation properties. Remains stable in the building structure throughout the life of the building: it does not shrink and prevents cracks from forming.
High strength - the cellular structure is formed by melting materials, characterised by high strength at low density. Granulated GRANUGLASS is 10 times lighter than water, so it stays on the surface. The strength characteristics do not change over time and do not deteriorate when exposed to an aggressive environment. When used in building mixtures, it forms an elastic structure in the product, so that the resulting materials can withstand high deformation loads and have increased abrasion resistance.
Low Crystalline Silica Content in Aragatsperlite: Safety Confirmed by Research

Safety / Features
The sand used in the production of GRANUGLASS - Aragatsperlite, our natural mineral raw material and finished product, is distinguished by its exceptionally low and safe content of crystalline silica (quartz), as confirmed by independent, specialized X-ray diffraction (XRD) analyses.
Scientifically Confirmed Safe Composition
The latest detailed quantitative analysis using X-ray diffraction (XRD) and the Rietveld method has unequivocally shown that Aragatsperlite is characterized by:
-
Very high content of amorphous substance: at a level of ~96%.
-
Extremely low quartz (crystalline silica) content: below 1.1% by weight.
-
Trace presence of zeolites (gmelinite and mordenite): at a level of 3-4%.
Why is this so important?
Compliance with EU Regulations and User Safety
Crystalline silica (RCS), particularly in the form of respirable dust, is classified in the European Union as a carcinogenic substance (Category 1A according to the CLP Regulation). Its presence in the workplace is strictly controlled under Directive 2017/2398/EU and Directive 2004/37/EC (Carcinogens and Mutagens Directive).
Our product, with its confirmed quartz content significantly below 1%, minimizes the risks associated with exposure to respirable dust. In practice, this means:
-
Greatly facilitated compliance with the stringent Occupational Exposure Limits (OELs) in force in the EU.
-
Reduced health risk for workers during material processing, mixing, or application.
-
Greater safety for end-users of products containing Aragatsperlite.
-
Less burden in HSE management – reduces the need to implement the highest levels of collective and personal protective equipment.
High Quality and Predictable Properties
The dominant amorphous (glassy) phase not only guarantees safety but is also responsible for the excellent functional properties of Aragatsperlite as a lightweight aggregate, filler, or absorbent material. The amorphous structure ensures consistency of physicochemical parameters and high batch-to-batch repeatability.
Summary
By choosing Aragatsperlite, you are investing in a top-quality raw material whose safety is documented at a scientific level. We offer a material that not only performs its functional roles excellently but also helps meet the rigorous legal requirements of the European Union regarding workplace health protection, making it a reasonable and responsible choice for modern industry.
Content based on a detailed report from quantitative XRD analysis (Rietveld method) performed by an accredited laboratory. We are ready to provide full documentation.
The spherical shape of GRANUGLASS provides significant benefits
Granular GRANUGLASS
thanks to its low density and spherical shape, reduces production costs.
GRANUGLASS is a product with a closed porous structure, which gives it an almost zero absorbability. The surface of the perlite granules is coated with a vitreous crystallisation, which prevents the ingress of moisture. The water absorption of granulated perlite is lower (0.5%) than that of crushed foam glass (5%).
The spherical shape of GRANUGLASS provides significant advantages. As a loose fill, it perfectly fills even uneven and curved voids. When used as an additive to building mixes makes the product easier and more convenient to use. The spherical form of the granules facilitates its application and even distribution in mixtures.
Low thermal conductivity
low thermal conductivity GRANUGLASS, thanks to its gas-filled cellular structure, retains heat and cold perfectly. Gas, it retains heat and cold perfectly, being an excellent thermal insulation material.
Sound insulation - thanks to its gas-filled cellular structure, perlite prevents the passage of sound. Thanks to its spherical shape, it distributes itself evenly in the thermal and acoustic insulation layer without deteriorating its properties.
Chemical and biological resistance - chemically resistant material. Does not cause mould. Unfavourable environment for the proliferation of parasites, rodents and plants.
Easy - granulated GRANUGLASS is lightweight, making it particularly suitable for insulating beams and old building structures. The lightweight material is easy to work with!
Environmentally safe - granulated GRANUGLASS is non-toxic, odourless, does not emit dust and does not cause skin irritation or allergies. Made from natural volcanic rock. Fully recyclable. Disposable without harming the environment or human health.
Fire-resistant - GRANUGLASS is a non-flammable material and does not emit gases or fumes when heated. Application temperature from -200°C to +600°C.
