3M™ Venting Tape 3294 is a pink non-woven, synthetic backing with a strip-coated low-tack pressure sensitive acrylic adhesive for use in various venting applications requiring high outgassing rates.

3M™ Venting Tape 3294
Allows air and gases to escape while keeping solids in place
Conformable, Non-Woven Backing Offers High Air/Gas Permeability
We manufacture 3M™ Venting Tape 3294 to meet various high outgassing requirements for foam-in-place insulation processes in appliance and other industries. The acrylic adhesive is strip-coated so uncoated areas have higher permeability to help minimize foaming voids. The non-woven, synthetic backing is conformable with good burst strength for effective sealing and minimal foaming voids to help reduce clean-up.

Recommended applications:
  • To allow the confinement and outgassing of foam insulation
Used in Foam-In-Place Manufacturing Process
A common challenge in refrigerator and freezer manufacturing is the venting of insulation foam gasses while keeping foam in place. Our venting tape is used to cover openings in the cabinet of refrigerators and freezers during the foam-in-place manufacturing process. It allows air and gases to escape while keeping solids (such as urethane foam) in place. The air-permeable, non-woven backing of 3M™ Venting Tape 3294 keeps foam-in-place insulation inside door and appliance cavities, while helping eliminate voids.
