Armaflex tape-adhesive Foam Insulation Tape | Thermal Sealing for pipes & Ducts_ Nairobi Kenya.

Armaflex Self-Adhesive Elastomeric Foam Insulation Tape is a high-performance thermal sealing solution designed to prevent condensation, sweating, and energy loss on HVAC, refrigeration, and plumbing pipework. Made from flexible, closed-cell elastomeric foam with a pressure-sensitive adhesive backing, this 3mm-thick tape easily wraps around complex pipe fittings, valves, joints, and tight corners to create a continuous moisture barrier.
Key Highlights:
  • Thickness & Size: 3 mm thick × 50 mm wide
  • Thermal Efficiency: Prevents heat gain/loss and condensation on hot/cold lines
  • Vapor Seal: High-resistance closed-cell structure prevents moisture ingress and corrosion under insulation (CUI)
  • Easy Application: Self-adhesive backing with a peel-off liner for fast, hassle-free installation

Product Description
Armaflex insulation tape is a flexible, closed-cell elastomeric foam tape engineered for thermal insulation, vapor sealing, and condensation control. 1 It is widely used in HVAC, refrigeration, plumbing, and industrial systems to wrap around complex pipe fittings, valves, joints, and tight corners where rigid or tubular insulation cannot easily conform.

Key Features & Benefits

  . Condensation Control: The closed-cell foam structure forms a built-in          vapor barrier that prevents pipe “sweating,” moisture ingress, and                        subsequent corrosion under insulation (CUI).
  . Energy Efficiency: Reduces thermal loss or heat gain on hot and cold             line  connections, reducing energy consumption for HVAC and                            refrigeration  equipment.
   .High Flexibility: Easily wraps around irregular shapes, T-joints, valves,          elbows, and short pipe runs without tearing or cracking.
   .Microbial Resistance: Often built with antimicrobial protection (e.g.,             Microban®) to resist mold and fungal growth.   


Key Applications

       .HVAC & Refrigeration: Insulating suction lines, copper refrigerant                 pipes, and ductwork joints.
       . Chilled Water & Plumbing: Sealing pipe connections to prevent drip           damage in commercial and residential buildings.
       .Cold Rooms & Chillers: Wrapping valves, fittings, and thermal                       bridges  in cold storage facilities.
       .Repair & Sealing: Patching damaged areas on existing Armaflex pipe            tubes or sheet insulation to restore continuous thermal coverage.  


Application Instructions

        1. Surface Prep: Ensure the target pipe or substrate is clean, dry, and                  free from oil, dust, or rust.
2. Wrapping: Peel back the protective paper backing and apply the                        adhesive side directly to the surface.
3. Overlapping: Wrap the tape around the pipe with a 50% overlap to               ensure seamless continuous coverage without air gaps.
       4.Firm Pressure: Smooth down firmly along the seam to ensure proper              bonding of the pressure-sensitive adhesive.
