Polysurlyn Moisture Barrier

THE MOISTURE BARRIER (PSMB) ISOLATES THE LAYERS OF INSULATION FROM THE JACKETING MATERIAL, AVOIDING MOISTURE PENETRATION AND METAL-TO-METAL CONTACT TO PREVENT CREVICE, PITTING AND GALVANIC CORROSION. IT ALSO PROTECTS THE INSULATION AND UNDERLYING PIPE/VESSEL FROM ANY PHYSICAL DAMAGE, UV EXPOSURE, CORROSIVE ATOMSPHERES AND WATER.

THE POLYSURLYN MOSITURE BARRIER (PSMB) IS A THREE LAYER CO-EXTRUDED SYSTEM WHICH USES POLYETHYLENE AND DuPont™ Surlyn® POLYMERS WITH A TOTAL FILM THICKNESS OF 3 MILS (76 µm) THAT IS HEAT LAMINATED IN THE FACTORY TO THE INTERIOR SURFACE OF ALUMINIUM JACKETING. THIS MOISTURE BARRIER’S THREE LAYERS ENSURES THE ELIMINATION OF ANY PIN-HOLES IMPARTING EXCELLENT MOISTURE RESISTANCE PROPERTY TO THE FILM.
