Description

Aluminum alloy 3105-H14 or 3000/3003-H14 with PSMB( 75 micron ) at one side and other side is bare Stucco finish coils 0.5mm x 1219mm

PFMB/PSMR is a type of material that is applied to aluminum coils in order to prevent moisture from penetrating the surface. This is typically done to protect the aluminum from corrosion and other forms of damage that can occur as a result of exposure to moisture. PSMB, or Polysurlin Moisture Barrier, is similar to PFMB/PSMR and also used to prevent moisture to penetrate the surface on the Aluminum alloy 3003-H14 coils with PSMR( 75 micron ). It is a polyethylene-based product which is used as a moisture barrier on aluminum coils. Both are used as a protective layer to protect the aluminum coils from moisture

Since most people commonly think of corrosion in the industrial sector when they think of pipes, they are often aware of the risks that arise from corrosion under insulation (CUI). Many people neglect the inside surface of the metal jacketing while discussing corrosion. Corrosion can and does happen when water is present in a jacketed insulation system and comes into contact with the inside surface of the metal jacketing. In all situations (hot and cold), with all metal jacketing types, and with all insulation kinds, this form of corrosion on the internal surface of insulation jacketing is a hidden, serious, and expensive problem. The jacketing system becomes weaker as it corrodes from the inside, which can lead to increased water intrusion or damage to the insulation, vapor barriers, or pipes below the jacketing.
