Raw perlite
Raw perlite is a rock of volcanic origin which is crushed, dried and sorted into individual fractions in the processing process at the production facility.
Depending on the grain size, our company offers 7 basic fractions and a number of combinations of these fractions in virtually any number and ratio of the basic fractions to achieve a wider range of grain sizes.
