Garden Perliete and ore perlite
Perlite is an amorphous volcanic glass that has a relatively high water content, typically
formed by the hydration of obsidian. It occurs naturally and has the unusual property of
greatly expanding when heated sufficiently. It is an industrial mineral and a commercial
product useful for its light weight after processing. When it reaches temperatures of
850–900 °C, perlite softens (since it is a glass). Water trapped in the structure of the
Our perlite has many specifications, such as 8-16 meshes, 16-20 meshes, 20-40
meshes, 30-50meshes, 50-70meshes, 70-90 meshes, 90-120 meshes.Our ore is located
in Northeast area, where is very famous in the natural source, with top grade quality,
high purity of over 95%.
material vapourises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material
is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m³
(1.1 g/cm³), while typical expanded perlite has a bulk density of about 30–150 kg/m³.
It is widely used in construction building products,horticultural aggregate,fillers,fillers aid and so on.
