perlite

1. Description:

The material comes from volcanic lava. It is a kind of amorphous, glassiness volcano that contains crystalline water inside.

For expanded perlite has low density and low heat conductivity characters, it is widely used in construction and manufacturing fields,lightweight plasters and mortars, insulation, ceiling tiles and filter aids.

2. Perlite specification:
