Expanded perlite for cryogenic insulation

Perlite magnified

Cryogenic and low temperature insulation using expanded perlite

Liquefied gases having boiling points as low as -452°F (-269°C) have created a demand for storage facilities capable of economically reducing evaporation losses.


Perlite, widely used for insulation because of its low thermal conductivity, cost, ease of handling, nonflammability and low moisture retention, performs well in insulating cryogenic and low temperature storage tanks, air separation units, cold boxes, nitrogen, oxygen, argon and LNG storage facilities, and in food processing
