39 Super Insulating for Evacuated Cryogenic Service - Perlite

Thermal conductivity of evacuated perlite is many times lower than that of nonevacuated perlite insulation. For example, at a mean temperature of -115°F (-82°C), normal unevacuated cryogenic perlite at 4 lb/ft3 (64 kg/m3) would have a thermal conductivity about 22 times as great as evacuated perlite at 8.7 lb/ft3 (139 kg/m3) and interstitial ...

A Guide for the Bulk Handling of Expanded Perlite

(3) High-pressure, low-air-volume systems with high ratio of perlite to air (1-15 psi, ratio of 1 /3 through 1/10). A vacuum can be drawn on a storage silo or cryogenic vessel (Fig. 1) and the perlite is pulled through a hose or pipe, to be settled out in the tank without the use of a cyclone. As shown here, this is a low-pressure system.
