HT/ArmaFlex is a flexible closed-cell elastomeric foam insulation for use in high-temperature applications of up to 150°C. This thermal insulation material reduces the risk of corrosion under insulation (CUI) and has a built-in UV-resistance for long service life.Applications for this flexible foam include thermal insulation of pipes, vessels and ducts in solar collectors (including outdoors), motor vehicles, hot gas lines as well as steam lines and dual temperature lines.
