PolySurlyn Laminated Aluminum Coil is an industrial-grade aluminum jacketing material with a high-strength polymer moisture barrier hot-bonded to the inner surface of the aluminum coil. It helps reduce the risk of corrosion caused by contact between aluminum and wet insulation materials.
Haomei Aluminum supplies PolySurlyn Laminated Aluminum Coil using 1060, 3003, or 5052 aluminum alloy as the base metal. The inner side is heat-bonded with an approximately 3-mil (76–80 micron) blue or clear polymer film. This product is suitable for insulated pipes, tanks, towers, valves, elbows, vessels, and a wide range of industrial equipment requiring durable metal protection.
What Is PolySurlyn Laminated Aluminum Coil?
PolySurlyn Laminated Aluminum Coil, also called PSMB Aluminum Coil or moisture-barrier aluminum coil, is a composite material made by hot-press bonding an aluminum coil with a multilayer polyethylene/Surlyn polymer moisture barrier.
The key difference between this material and conventional insulation aluminum jacketing is the continuous, tear-resistant polymer layer on the inner side. The film helps isolate moisture, oil, and certain chemical contaminants, reducing direct contact between the aluminum base metal and wet insulation wool, salts, or condensed water. For this reason, it is particularly suitable for high-humidity areas, coastal projects, corrosive chemical environments, and insulation systems requiring long-term reliability.
For applications requiring only basic exterior protection, customers may also choose Mill Finish Aluminum Coil. However, for insulation systems that require an additional moisture barrier on the inner side, PolySurlyn Laminated Aluminum Coil is the more appropriate option.

PolySurlyn Moisture Barrier Functions in Aluminum Jacketing Systems
The polymer moisture barrier used by Haomei Aluminum provides high tear strength, good work of fracture, and strong dynamic performance. It is designed to remain stable during fabrication, profiling, transportation, and on-site installation. The moisture barrier mainly helps to:
- Isolate water vapor and liquid water from the insulation layer.
- Reduce direct contact between aluminum, oil, moisture, and contaminants.
- Lower the risk of corrosion under insulation.
- Improve the stability of aluminum jacketing systems in demanding environments.
- Maintain protective performance during bending, wrapping, and profiling operations.
Blue is the most common moisture-barrier color because it makes it easier for workers to distinguish the inner surface from the outer surface during installation. Clear film is also available for projects with specific color or appearance requirements.
Available Aluminum Alloys: 1060, 3003, and 5052
Different industrial environments require different levels of strength, corrosion resistance, and formability. Haomei Aluminum can recommend a suitable alloy according to the operating conditions, corrosive media, fabrication method, and project specifications.
1060 PolySurlyn Laminated Aluminum Coil
1060 is a commercially pure aluminum alloy with good ductility, thermal conductivity, and fabrication performance. It is a cost-effective option for general insulation pipelines, ventilation ducts, and equipment jacketing projects where corrosion requirements are relatively moderate.
3003 PolySurlyn Laminated Aluminum Coil
3003 aluminum alloy contains manganese and offers higher strength and better corrosion resistance than 1060. It is one of the commonly used materials for insulation jacketing in petrochemical plants, power facilities, and industrial pipe systems. For projects that require a balance between formability and durability, 3003 is often a practical choice.
5052 PolySurlyn Laminated Aluminum Coil
5052 provides higher strength and better resistance to marine and high-humidity environments. It is suitable for coastal regions, offshore projects, humid industrial sites, and facilities exposed to certain corrosive media. For demanding equipment jacketing applications, 5052 PolySurlyn laminated aluminum coil can offer more robust base-metal performance.
Surface Finishes of PolySurlyn Laminated Aluminum Coil for Insulation Jacketing
The outer surface of PolySurlyn Laminated Aluminum Coil can be selected according to installation methods, appearance requirements, and project specifications.
- Smooth Aluminum Coil: A flat and clean surface suitable for standard equipment and straight pipe cladding.
- Stucco-Embossed Aluminum Coil: Commonly available in orange-peel or stucco-embossed patterns. It can reduce the visual impact of minor scratches during transportation and installation while adding surface rigidity. Learn more about our Embossed Aluminum Coil.
- Corrugated Aluminum Coil: Suitable for applications requiring a more structured surface profile or a specific cladding process.

PolySurlyn Laminated Aluminum Coil Applications
PolySurlyn Laminated Aluminum Coil is not simply a decorative building material. It is designed primarily for long-term protection in industrial insulation systems. Typical applications include:
- Insulated pipelines and storage tanks in oil refineries.
- Petrochemical units, reactors, vessels, and tower equipment.
- Thermal power plants, nuclear auxiliary systems, and district heating pipelines.
- LNG facilities, cryogenic equipment, and cold insulation systems.
- Equipment cladding in chemical, pharmaceutical, and food-processing plants.
- Marine engineering, coastal industrial facilities, and high-humidity projects.
- HVAC ducts, heat exchangers, and industrial boiler insulation protection.
In cold insulation systems and humid environments, continuity of the moisture barrier is particularly important. During design and installation, attention should be given to overlap direction, seam sealing, rivet locations, and insulation dryness to maximize the protective function of PolySurlyn laminated aluminum coil.
Advantages of PolySurlyn Laminated Aluminum Coil for Insulation Jacketing
Helps Prevent Corrosion Under Insulation
The moisture barrier is located on the inner side of the aluminum coil and acts as an isolation layer between the aluminum and insulation material, reducing the harmful effect of trapped water, salts, and chemical residues.
Strong Bonding, Low Peeling Risk
The polymer film is firmly bonded to the aluminum substrate through a hot-lamination process. Under normal processing, bending, transportation, and installation conditions, the barrier layer is not easy to peel off.
Strength and Fabrication Performance
H14 and H16 aluminum tempers provide suitable rigidity for cutting, rolling, bending, profiling, and wrapping. Different alloys, thicknesses, and finishes can be selected for various pipe diameters and equipment geometries.
Lightweight and Weather Resistant
Aluminum is lightweight and convenient for handling and installation. It also offers good outdoor weather resistance against sunlight, rain, and certain acid-rain conditions.
High-Performance Polymer Film
The polymer barrier has high strength, good tear resistance, strong fracture performance, and reliable dynamic strength. It helps preserve the integrity of the moisture barrier during fabrication and handling.

FAQ – PolySurlyn Laminated Aluminum Coil
What is the difference between PolySurlyn Laminated Aluminum Coil and ordinary aluminum jacketing?
The main difference is the moisture barrier bonded to the inner side of the aluminum coil. Ordinary aluminum jacketing mainly provides exterior protection, while PolySurlyn Laminated Aluminum Coil offers additional moisture resistance and corrosion protection, making it more suitable for insulation systems exposed to condensation, humidity, and harsh environments.
How should I choose between 0.6 mm and 0.8 mm PolySurlyn laminated aluminum coil thickness?
A 0.6 mm thickness is commonly used for standard pipe insulation jacketing because it provides a good balance of cost, strength, and formability. A 0.8 mm thickness is recommended for larger-diameter pipelines, storage tanks, equipment insulation, or projects requiring higher mechanical strength and rigidity. The final thickness selection depends on pipe size, installation conditions, wind load, and project requirements.
Which aluminum alloy is better for petrochemical insulation projects: 3003 or 5052?
3003 aluminum alloy is widely used for most petrochemical insulation jacketing applications due to its good formability and corrosion resistance. For coastal projects, high-humidity environments, salt spray exposure, or applications requiring higher strength and corrosion resistance, 5052 aluminum alloy is usually the preferred choice.
Will the moisture barrier crack during bending or fabrication?
No. Under normal forming conditions and with a suitable bending radius, the hot-bonded polymer moisture barrier provides excellent flexibility and is resistant to cracking during standard fabrication. For special profiling or complex forming processes, a trial production test is recommended before full-scale manufacturing.
