Expanded perlite is a new material with multi applications. Due to excellent characteristics,
Excellent chemical stability,
Low coefficient of thermal conductivity,
Weak water absorption,
Non-toxic, non-smelling,
Excellent insulation properties,
Low bulk density etc.,
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.
