3M 7000049897 Venture Tape 1555CW Foil Tape 1.88in X 50yd

Product Description

The 3M 7000049897 is a cryogenic vapor barrier foil tape in the Venture Tape 1555CW series, engineered for low-temperature vapor barrier joint closure applications. It features a durable aluminum foil core laminated between two layers of 0.5 mil polyester film, creating a zero-permeable barrier that blocks moisture transmission at seals and seams. The multi-layer laminate is coated with a pressure-sensitive cold-weather acrylic adhesive that maintains bond strength well below freezing. HVAC and insulation contractors use this tape where conformability, puncture resistance, and reliable adhesion in extreme cold are required.

This tape is suited for insulation jacketing, cryogenic piping, and cold-storage vapor barrier work in both commercial and industrial settings. The flexible backing conforms to irregular, curved, and uneven surfaces, making it practical for field installation on pipe fittings, ductwork penetrations, and pre-insulated panel seams. It is appropriate for applications where standard foil tapes fail due to low ambient or service temperatures. Each roll measures 1.88 inches wide by 50 yards long.

Key Features

• Zero-permeable laminate construction provides a continuous vapor barrier at joints and seams
• Aluminum foil core sandwiched between two 0.5 mil polyester film layers resists pinhole formation
• Cold-weather pressure-sensitive acrylic adhesive bonds reliably in sub-freezing temperatures
• High puncture and tear resistance for demanding cryogenic and cold-storage environments
• Flexible, conformable backing adheres to curved and irregular surfaces

Compatibility

Designed as an OEM-style vapor barrier tape for low-temperature insulation sealing applications including cryogenic piping, cold-storage panels, and HVAC insulation jacketing where a zero-permeable foil tape is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors. Surfaces should be clean, dry, and free of frost or oil before application. Apply firm, even pressure across the full tape width to ensure full adhesive contact with the substrate. Follow applicable mechanical insulation and vapor barrier specifications for the project.
