Adhesive Aluminum Foil Tape

• Tape Description

  This professional-grade aluminum foil tape is constructed with a high-tensile 125-micrometer aluminum foil backing coated with a specialized solvent acrylic adhesive. The result is a highly flexible tape that conforms effortlessly to irregular shapes and surfaces while maintaining structural integrity.

  Designed for longevity, the AFA125175 withstands extreme thermal cycles, ranging from freezing conditions to intense heat. Its superior weathering resistance ensures that it remains bonded and effective in both indoor and outdoor applications, providing a permanent seal against vapor and air leaks.

• Features & Benefits

  • Superior Backing Thickness: The 125um foil provides enhanced puncture and tear resistance compared to standard foil tapes.
  • Thermal Management: The polished aluminum backing offers excellent reflection of both heat and light, protecting sensitive components and improving energy efficiency.
  • Industrial Solvent Adhesive: Coated with a high-quality solvent acrylic adhesive that delivers super strong adhesion and long-term holding power.
  • Ultimate Vapor Barrier: Features a low moisture vapor transmission rate (MVTR), making it ideal for preventing condensation in insulation systems.
  • Extreme Temperature Tolerance: Maintains performance across a wide service range from -30 °C to +150 °C.
  • Flexible & Conformable: Easily adapts to uneven or complex surfaces without lifting or cracking.

Applications

The Adhesive Aluminum Foil Tape is a versatile tool across multiple specialized industries:

• HVAC Systems: Permanent sealing of joints and seams in ductwork to prevent air leaks and moisture ingress.
• Electrical: Used for EMI/RFI shielding and heat dissipation in electrical assemblies.
• Construction: Sealing insulation materials and vapor barriers to improve building thermal performance.
• Outdoor Repair: Patching metal surfaces and sealing gaps in exterior ducting due to its high UV and weather resistance.

FAQ:

Q1: What is the total thickness of this tape?
A: The tape has a total thickness of 175um (0.175mm), which includes a 125um (0.125mm) aluminum backing and the adhesive layer.

Q2: Can this tape be used for outdoor HVAC units?
A: Yes. Its solvent acrylic adhesive and thick foil backing are highly resistant to weathering, UV rays, and extreme temperature fluctuations, making it perfect for outdoor use.

Q3: Is it fire-resistant?
A: Aluminum is naturally non-combustible and provides excellent heat resistance up to +150 °C, helping to prevent the spread of flames in ducting systems.

Q4: Does it stick to fiberglass insulation?
A: While primarily designed for metal surfaces and FSK (Foil-Scrim-Kraft) facings, its high-tack adhesive bonds well to most clean, dry construction materials.
