The perlite is an acidic, glassy volcanic rock containing a certain amount of adherent water and a small amount of crystalline phase, too (feldspar, quartz etc.)

By the effect of an abrupt warming up the perlite gets into a pyroplastic state and the pressure of the inner adherent water creates a spatial expansion. The extent of the thermal expansion changes depending on the quality of the raw material, the expansion temperature and time between 1:10 and 1:20.

Hungary's only one perlite quarry is to be found in Pálháza. The quarry has been in operation since 1959. The milling, drying and grading of perlite is made in a dressing plant near-by the quarry, according to the demand of the customers. Perlit-92 Kft. has opened its second mine in 2006, that ensures raw perlite supply for another 80 years. Important developments in the last 5 years:
    - environment protection
    - mining machinery
    - development of the grinding and classifying works
    - modernization of transport

We perform our work on the basis of the "Declaration on Quality Policy" of the ISO 9001 Quality Assurance System qualified by TÜV CERT.

Major applications of the expanded perlite:

Building industry and equipment operating on a high temperature:
- Heat insulation (
mortars, plasters, önterülő insulations)
- Sound-proofing
- Making of lightweight constructions
  (light concretes)
-  Perlite sheets and forms

Food industry:
- Filtering of beer, edible oil, vinegar, syrups

Pharmaceutical industry:
- Filtering of antibiotics

Agriculture:
- Amelioration, planting, liquid dung treatment, carrier for plant protection agents

Environment protection:
- Blotting of oil pollutions from water surface, filtering of swimming pools'
  water

Industrial equipments:
- refrigeration  technique, heat insulation

Paint production, plastic industry:
- filler

The raw perlite gets to an extensive application on the area of metallurgy and foundry as slag enchaining and insulating cover dust.

The applications of perlite are continuously broadening. In the countries where special attention is paid to the protection of the environment the environmental friendly perlite is more and more used instead of artificial materials of similar properties.
