ArmaGel® HTL — Technical Overview & FAQs

What is ArmaGel® HTL?

ArmaGel® HTL is a low-density, high-temperature aerogel insulation blanket engineered for industrial systems that require excellent thermal efficiency at elevated operating temperatures. As part of Armacell’s advanced aerogel portfolio, HTL combines ultra-low thermal conductivity with a lighter, more flexible construction—making it easier to install, handle, and maintain compared to traditional high-temperature insulation materials.

HTL is designed to reduce heat loss, improve system efficiency, and help mitigate corrosion under insulation (CUI) in refineries, petrochemical facilities, and power generation environments.

Where is ArmaGel® HTL typically used?

• Refinery and petrochemical hot-service piping
• High-temperature industrial equipment and vessels
• Power generation, turbines, and heat-trace lines
• Chemical processing systems
• Applications requiring lighter, easier-to-install high-temperature insulation

What makes ArmaGel® HTL different from other insulation materials?

• Lower density design for easier handling and reduced installation fatigue
• Exceptional thermal performance powered by aerogel technology
• Reduced insulation thickness compared to mineral wool or calcium silicate
• Hydrophobic construction to help prevent moisture ingress and CUI
• Flexible blanket design for faster, simpler installation
• Suitable for congested piping and tight-access areas
• Compatible with metal jacketing and fabricated insulation systems

Is ArmaGel® HTL resistant to moisture and CUI?

Yes. ArmaGel® HTL offers superior hydrophobicity, helping to:
• reduce moisture absorption
• limit corrosion under insulation
• maintain thermal performance over time
• resist environmental exposure during service

Hydrophobic performance remains effective even after cutting or shaping the insulation.

Is ArmaGel® HTL safe and suitable for industrial environments?

Absolutely. ArmaGel® HTL is engineered for the demands of refinery and chemical-processing operations. It is:
• designed for reduced dust compared to traditional aerogels
• compatible with hot-service industrial applications
• safe for installation with appropriate PPE
• compliant with common jacketing and cladding systems
