Perlite is a volcanic mineral siliceous rock composed mainly of aluminum silicate. Each perlite particle possesses an important amount of occluded water, which allows it to expand through thermal procedures, which then results in Expanded Perlite.

Harbolite exploits and processes perlite rock to supply for a wide range of applications such as:

• Filtration

• Food for animals

• Horticultural applications

• Construction

• Industrial Insulator
