Cryogel Z Flexible Aerogel Blanket Insulation

Cryogel Z Flexible Aerogel Blanket Insulation

Cryogel Z flexible aerogel blanket insulation is engineered to deliver maximum thermal protection with minimal weight and thickness. Cryogel Z is composed of a flexible aerogel blanket laminated to a vapor retarder. This powerful combination makes Cryogel Z unmatched in sub-ambient, cold cycling, and cryogenic applications.

Cryogel Z’s extremely low thermal conductivity minimizes heat gain and liquid boil-off. Cryogel Z remains flexible, even at cryogenic temperatures, eliminating the need for complex and costly contraction joints, thereby resulting in simple and faster installation. It is designed for long term performance while also withstanding incidental mechanical abuse, leading to continued protection through the life of the asset. Cryogel Z is ideal for faster and safer installations for both maintenance work and new builds.

In addition to being the first choice in cold conservation, Cryogel Z based systems offer acoustic attenuation and protections against cryogenic spill, pool fire, and jet fire. The combination of these safeguards make Cryogel Z ideal for onshore, offshore and marine applications.

Performance of Systems Incorporating Cryogel Z

The performance of Cryogel Z in cold acoustic service and passive fire protection systems has been evaluated according to the test methods described below. Performance levels achieved in these systems are configuration dependent. Contact Aspen Aerogels technical service for configuration and other details.
• UL 1709 – Rapid Rise Fire Test: Up to 150 min of protection
• OTI-95-634 – Jet Fire Protection: Up to 120 min of protection
• ISO 15665 – Acoustic Insulation for Pipes, Valves, and Flanges: Configurations meeting Class A2, B2, C2, and Shell D2 possible
• IMO Part 2 and 5: Effective July 2019, use only Cryogel Z (IMO grade) for applications requiring compliance with IMO Part 2 and 5. Standard grade Cryogel Z is only appropriate for applications that do not require compliance with IMO Part 2 and 5. Contact Aspen technical service for additional information.
