Chemical-Resistant Cellular Glass Pipe Insulation
Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines. Insulation is flame resistant, meeting ASTM E84 0/0 for flame and smoke. Seal with tape (sold separately). Outdoor and underground use require metal jacketing (sold separately).
Tubes have a kraft paper jacket with an adhesive strip for sealing.
