Perlite for Industry

Industrial applications

Being lightweight, non-combustable, and insulating, perlite has been found to be useful in a wide variety of industrial applications. Perlite can safely be used over a wide range of temperatures. Use it in refractory brick, high temperature insulation, molten metal topping, cryogenic insulation, filtration, and lightweight fillers.
