The superior insulating performance of ROHACELL® HERO is an added advantage.
The rigid structural foam not only provides mechanical strength at all of its very low densities, but the innovative closed-cell foam also insulates applications quite effectively from hot or cold environments.
Lightweight “Dual-Use” Sandwich Panels
The ROHACELL® HERO panels are distinctively “dual-use” as it provides both thermal insulation and mechanical strength. Their impressive mechanical strength can fulfill structural demands, while simultaneously suppressing heat transfer.
Potential dual-use sandwich panel applications include shelter systems in harsh environments, satellites, space applications, protective enclosures for components in high altitude aircraft, etc.
Excellent Insulating Performance – At Any Density
Thermal conductivity changes depending on the density of the ROHACELL® HERO product grade.
Thermal performance or insulating capacity increases with the decrease in product density. However, excellent thermal conductivity takes place at all densities.
