Product introduction

Expanded perlite is a natural acidic glassy volcanic lava, a non-metallic mineral, including perlite, pine resin and obsidian, the three of which differ only in their crystal water content. Due to the rapid expansion of its volume by 4 to 30 times under the high temperature condition of 1000 1300 , it is collectively called expanded perlite. Generally, the expansion ratio is> 7 to 10 times (obsidian> 3 times, available), and about 70% of silica.

It can be used as filter, catalyst, molecular sieve and carrier for rubber, fertilizer, pesticide. Widely used in construction, metallurgy, petroleum, machinery, light industry, hydropower, foundry, medicine, food, agriculture, forestry, gardening and other departments.
