Pelite is a natural volcanic mineral, mined in opencast mines in different parts of the world (e.g. Slovakia, Greece, Hungary, USA, China) in the form of a grey stone. After preliminary treatment, perlite ore undergoes the process of expanding, i.e. short influence of high temperature (about 1000o C). Then the water contained in the grains evaporates rapidly, causing expansion of the material. The grain expands even 20 times. The final product reminds roasted corn in terms of structure and appearance and in terms of the chemical composition it reminds glass. Porous structure of perlite determines its perfect insulation properties. PERLIPOL offers different fractions of perlite, as well as hydrophobised Hydroperls perlite. Hydrophohic perlite serves as an absorbent, but is also applied wherever the water absorption of perlite is undesirable.

EXPANDED (EXFOLIATED) VERMICULITE
Vermiculite is a mineral. It contains thin, shiny plates of goldish colour. It contains a small quantity of water in its structure. The mineral, broken into appropriate particles, is heated in the explanation process (exfoliation) up to the temperature of about 1000 oCelsjusza As the result of a thermal shock the grain volume in increasing almost 30 times. Expanded vermiculite has a structure reminding small expanded folding. Large amount of air, contained in every particle, results in low bulk density and very good thermal insulation properties.
Advantages of expanded vermiculite:
- durability and light weight,
- perfect thermal insulation properties,
- resistance to high temperature,
- noise dumping,
- environmental harmlessness,
- chemical neutrality.
PERLITE PLASTERS AND MORTARS
Perlite plasters are very light. Sand in such plasters is replaced with perlite. They have very good thermal insulation properties, insulate both heat and sound. These plasters are chemically neutral and fireproof. Perlite plasters are applied both outside and inside. Mortars eliminate thermal bridges.
FLOOR AND ROOF FILLINGS
Perlite fillings may be applied at any ceiling and under any flooring. Arrangement of screed boards on perlite filling makes the whole structure light, warm and quiet.
For thermal and acoustic insulation of wooden ceilings, perlite may be used in the form of granulate (loose backfill). Perlite EP180 is used for insulation of ceilings.
Perlite backfill is intended for fireproof, warm and resistant to pressure flooring levelling mixtures in houses, public buildings, farming and industrial buildings. It is suitable for levelling mixtures on reinforced concrete or prefabricated or any other ceilings, intended for traditional concrete levelling mixtures, where there are problems with correct fixing of styrofoam or mineral wool due to uneven surface.
When we replace sand with perlite during manufacturing construction blocks, we obtain products with perfect properties, as light weight, thermal insulation, noise absorption and fire resistance.
Addition of expanded perlite for construction mixtures as mortars, plasters, adhesives, lowers its specific weight and improves workability. This mainly applies in gypsum and cement plasters as well as in styrofoam and tiles adhesives.
Perlite is used for regulating density of cement mass, e.g. in the process of borehole cementing.
Fireproof mortar protects structures from high temperatures. It is composed of perlite, vermiculite, binding agents and is applied as a spray. It is suitable for protecting metal bars, walls and concrete ceilings, wooden posts and metal parts. The mass is also used for assembly of fire doors, cable and pipe passages in walls and ceilings.
The market also offers perlite and vermiculite boards, applied in fire barriers, walls and ceilings.
Perlite and vermiculite are valued as a substrate for many plants. Applied independently or with another substrate, they create perfect conditions for plants.
The main advantages of perlite and vermiculite is soil aeration and working, which enables the roots breath easily, store water and give it back gradually.
Perlite is used as an addition to forage, where it plays the role of a natural anticaking agent and is a carrier of liquid additives, as unsaturated fatty acids, vitamins and medicines.
Perlite is very light and characterised by a porous structure. It prevents excessive roots growing. In hydroponics, perlite is used at drop watering or as an addition to the rock wool or coconut fibre in order to improve their properties.
Perlite and vermiculite is applied as a compound of thermal insulation backfills in blast furnaces and cryogenic chambers.
Perlite is for filtration in beer, wine, vinegar, soft drinks, juices, oil, sugar, pectin and water.
Perlite, especially hydrophobized perlite is used as an absorber for oil and gasoline in case of road accidents leakages, as they absorb liquid chemicals.
Perlite has some abrasive properties. The finest perlite fraction, EP100F is used as a gentle abrasive material, used for stainless steel, glass and varnishes.
Perlite, especially vermiculite, applied as agents protecting goods from breaking or damage. It applies to the protection of chemical products, as during a possible leakage, it absorbs dangerous substances and protect further spillage.
Perlite easily absorbs and stores fragrances and later releases them gradually.
Perlite is used at manufacturing of perlite bricks, characterised by a very low weight and perfect insulation properties. In these products, perlite is bound hydraulically.
They have special applications and are used as parts of cooling towers, stack tubes and pipeline insulation;
They are applied for fire and thermal insulation of any type of structures, as they characterise with high fire resistance and good thermal insulation.
