Ideal for Flexible HVAC Duct Work
We constructed 3M Metallized Flexible Duct Tape 3350 with a 1.6 mil polypropylene foil backing and a strong, pressure sensitive cold weather acrylic adhesive with a temperature range of -40°F (-40°C) to 185°F (85°C). This tape is flame, moisture, UV and chemical resistant and is commonly used for sealing flexible ducts and connector systems in residential and commercial construction.
