Perlite is ideal for insulating low temperature applications (- 4°C down to -100°C) and cryogenic applications (lower than -100°C, such as vessels used for the transportation or storage of very cold liquids).
The major advantages of expanded perlite in cryogenics and are the following:
- Low thermal conductivity (0.04-0.06 W/m.K at 24°C)
- Free flowing
- Non-settling
- Non-combustible
