Expanded perlite divide into closed cell, open cell.
Expanded perlite produce by coal gas furnace and electric furnace.
Welcome to contact us for detail specification and application guidence.
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.
