2" x 30' Foam Tape

Mars 93506 Pipe Insulation Foam Tape – Closed-Cell, Self-Adhesive Thermal Barrier

The Mars 93506 insulation tape is a closed-cell foam product designed for thermal protection on hot or cold piping systems. Manufactured with a self-adhering acrylic adhesive, this tape provides supplemental insulation to prevent heat loss and minimize condensation in HVAC and refrigeration piping.

It is suitable for both new installations and retrofit applications and can be applied directly over existing insulation or onto bare tubing. Its flexible composition allows for conformance to curved or irregular surfaces.

Product Features

• Material Type: Closed-cell elastomeric foam
• Adhesive: Single-side acrylic pressure-sensitive backing
• Temperature Range: 20°F to 200°F (-6.7°C to 93°C)
• Water Absorption: ≤ 5% by weight
• UV Resistance: Moderate

Physical Specifications

• Length: 30 feet per roll
• Width: 2 inches
• Thickness: 1/8 inch
• Color: Black

Applications

• ✔ Insulating suction lines in refrigeration and split system HVAC installations
• ✔ Wrapping piping components, valves, and fittings prone to sweating
• ✔ Supplementing existing insulation in confined or irregular geometries
• ✔ Ideal for reducing surface temperature differential to prevent moisture buildup

Installation Guidance

• Apply to clean, dry surfaces only
• Overlap each wrap slightly to maintain continuity of insulation
• Firm pressure ensures full adhesive contact; no mechanical fasteners required
• Do not use on surfaces exceeding 200°F

Performance Considerations

• Closed-cell structure limits vapor transmission and supports thermal performance
• Adhesive backing simplifies installation without the need for secondary bonding agents
• Can serve as a short-term repair option on compromised foam insulation jackets

The Mars 93506 foam insulation tape provides contractors with a reliable and easy-to-apply solution for reducing thermal losses and preventing condensation-related issues in piping systems. Its flexible, conformable form and durable adhesive backing make it suitable for a wide range of HVAC and plumbing applications.
