No moisture barrier needed
Flexible insulation from -200℃ to +125℃
No expansion joints required
Low thermal conductivity
These are flexible, closed-cell, rubber foams based on dienes rubber. Flexible elastomeric foams exhibit such a high resistance to the passage of water vapour that they do not generally require additional water-vapour barriers. Such high vapour resistance, combined with the high surface emissivity of rubber, allows flexible elastomeric foams to prevent surface condensation formation with comparatively small thicknesses.

No, these foams are closed-cell structures based on dienes rubber and exhibit extremely high resistance to water vapor transmission, rendering additional moisture barriers unnecessary.
The ULT (Ultra-Low Temperature) grade performs reliably between -200°C and +125°C, while the LT (Low Temperature) grade is designed for operating temperatures from -50°C to +105°C.
Due to its high water vapor resistance and the high surface emissivity of the rubber base material, it successfully prevents condensation with relatively thin insulation thicknesses.
No, expansion joints are not required because the elastomeric foam material maintains its flexible and elastic characteristics even at exceptionally low cryogenic temperatures.
Thermal conductivity is tested in accordance with ASTM C177, while the product density is evaluated using the ASTM D1622 testing methodology.
The foam possesses a closed-cell structural configuration with a close area percentage exceeding 95% under the ASTM D2856 test method, which guarantees excellent thermal and moisture performance.
