Aluminum Jacket with Polysurlyn Moisture Barrier

Aluminum roll jacketing with polysurlyn moister barrier is recommended for insulated piping, tanks and vessels. The aluminum roll laminated with polysurlyn composite materials with high strength and corrosion resistance already replaces the polykraft moisture retarders. The aluminum with polysurlyn composite material’s service life can reach 7 years without any maintenance, it has excellent resistance to corrosion.


Polysurlyn consists of 50-200um thickness of a polyethylene or a DuPont’s Surlyn which is heat and pressure bonded to the interior surface, provides a highly effective moisture retarder. Polysurlyn Moisture Barrier is heat laminated in the factory to the interior surface of all types of metal jacketing for mechanical insulation to help prevent pitting, crevice, and galvanic decomposition of the interior apparent of the metal jacketing and the underlying insulated pipe, tank, or equipment. This corrosion can occur when water enters the installed insulation system through joints or damage in the metal jacketing.

Polysurlyn is manufactured from 3 layers of film: 1 mil high-density polyethylene, 1 mil Surlyn, and 1 mil low-density polyethylene, with each layer carefully selected to yieldoptimum performance. This multilayer film is laminated to the interior side of aluminium and stainless steel jacketing using precise pressure and heat. Use of 3 mil thick three layer Polysurlyn Moisture Barrier (PSMB) film avoids the pinholes prevent in standard 1 mil single layer Polykraft Moisture Barrier(PKMB). When water is present and touching the metal jacket, corrosion can and does occur. This can happen in all applications (hot, cold, rooftop, industrial, commericial, etc.) and with all insulation types.

Polysurlyn moisture barrier has advantages:

1, Simple, low cost, and effective resistance to metal jacket and pipe corrosion;

2, Provides a barrier to crevice or pitting corrosion on the inner jacket surface in cold and hot pipe/tank applications;

3, Provides a barrier to galvanic corrosion of jacket or pipe in hot applications;

4, Minimal water absorption compared to kraft paper;

5, Will not deteriorate, discolor or shred when exposed to water;

6, Provides abrasion resistance during installation;

7, Long term durability and resistance to a wide range of environmental contaminants.
