CommodityExpanded perlite
Size: 60-80mesh, 100mesh, 1-3mm, 2-4mm, 3-6mm etc.
DescriptionPerlite comes from volcanic lava. For expanded perlite has low density and low heat conductivity characters. It is a kind of amorphous, glassiness volcano that contains crystalline water inside.
It is widely used in construction and manufacturing fields, lightweight plasters and mortars, insulation, ceiling tiles, filling thermal insulation material and filter aids.
In horticulture, it makes composts more open to air, while having good water-retention capacity. It is good carrier for soilless plant. Since last few years, expanded perlite is more and more popular in cryogenic use.

Expanded perlite is widely used in many industry areas.
1. Horticultural Applications
2. Construction applications
3. Heat insualtion brick/board etc.
Expanded perlite closed cell
Is a type of new expanded perlite which heated the big grit perlite in electric furnace and gotten uniform structure and hyaline surface grit, shape in round granular.
Its characteristics:
1. Shape in irregular spherical particles
2. Porous structure inside
3. Pure white color
4. High strength
5. Low thermal conductivity
6. Low bulk density
7. Low water absorption
8. High and low temperature resistant
9. Waterproof
