Polysurlyn Moisture Barrier Film

Polysurlyn Moisture Barrier Film are simple, low Cost and effective Resistance to metal jacket and Pipe Corrosion. They provide a barrier to crevice or pitting corrosion on the inner jacket surface in cold & hot pipe/tank applications. They are a barrier to galvanic corrosion of jacket or pipe in hot applications. Metal Jacketing and water don't mix. When the water is present & touching the metal jacket, corrosion can and does occur. This can happen in all applications ( hot, cold, rooftop, industrial, commercial, etc.) and with all insulation types.

Polysurlyn is manufactured from 3 layers of film:

1 mil high density polythylene, 1 mil surlyn and 1 mil low-density polythylene, with each layer carefully selected to yeildoptimum performancee. This multilayer film is laminated to the interior side of ITW's 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 grade single layer polykraft.

Polysulyn Advantages:

1) Minimal water absorbtion compared to Kraft paper.

2) Will not deteriorate, discolor or shred when exposed to water.

3) Provides absorbtion resistance during installation

4) Long term durability and resistance to a wide range of environmental contaminants.

5) Metal jacketing with PSMB has on ASTM E84 fame/smoke performance of less than or equal to 25/50

5) Aluminium Jacketing with PSMB Complies with
