NBR Elastomeric Foam Tube Insulation

​Product Overview
​​​​​​​
H-VAX NBR Elastomeric Foam Tube Insulation is a flexible closed-cell insulation solution designed to provide thermal efficiency, condensation control, and energy savings across a wide range of mechanical and industrial applications.
Manufactured from high-performance NBR elastomeric foam, it combines low thermal conductivity, excellent resistance to water vapor diffusion, and flexibility to ensure reliable performance under both low- and high-temperature operating conditions.
Its closed-cell structure minimizes heat transfer, prevents condensation, and helps protect piping systems against energy loss, making it suitable for H-VAX, refrigeration, plumbing, industrial processing, and building services.
