Products Description
Volcanic stone/
Lava rock/P
umice stone
is a kind of glass lava with dense pores.
The pore volume accounts for more than 50 percent of the rock volume.
It is called pumice because it has many pores, light weight, and can float on the water surface.
It is characterized by: high strength , heat insulation , sound adsorption , fire prevention , acid and alkali resistance , corrssion resistance, and no pollution, no radioactivity , etc.
