Applicable temperature for pearlescent sand: -200 to -800
Foam glass polyurethane can be used (it can operate down to –200°C).
Foamed polyurethane works perfectly, but insulation needs to be installed in advance； Insulation begins as soon as the leak test is completed.
Foamed polyurethane is suitable, with a usage temperature range of -200 to 120 degrees
