Manufacturers Expanded Perlite minerals for Refractory/Foundry materials
What is Perlite ?
Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets Perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume.
Character: Non-toxic, flavorless, lightweight, corrosion resisting, netural PH 6.5-7.5 etc.
Size: 100mesh, 200mesh, 0.15-1.18mm, 1-3mm, 2-4mm, 3-6mm, 4-8mm etc.
Unit Weight:(for reference)
- 1-3mm--------------60-90kg/CBM
- 2-4mm--------------60-100kg/CBM
- 3-6mm--------------60-100kg/CBM
- 4-8mm--------------70-110kg/CBM
