PSMB (Polysurlyn Moisture Barrier) Aluminum Coil Jacketing is a high-performance solution for pipeline protection, featuring a multi-layer protective film.

• First layer: PE film
• Middle layer: Zn++ Ionomer Surlyn
• Third layer: EAA
• Thickness: 0.076mm | Weight: 80g per square meter

Complying with ASTM C1729 standards, this moisture retarder ensures less than 5 pinhole detections and a water vapor transmission rate of less than 1.55g/m²/day.

Preventing Metal Jacketing Corrosion: Temperature imbalances between the interior and exterior of pipelines can cause condensation. Polysurlyn film acts as a superior moisture barrier to prevent corrosion on the interior surface of metal jacketing.

• High Durability: 0.080mm thick film for long-term protection.
• Moisture Resistance: Superior to Kraft paper; does not absorb water.
• Low Flammability: Enhanced safety for industrial environments.
• Zero Pinholes: Significantly fewer pinholes compared to Kraft paper or painted surfaces.
• Strong Bonding: High bonding strength to metal substrates using advanced raw materials.
