Product Information: 3M™ Vent Tape 394 features a unique, non-woven synthetic backing with high air/gas permeability, good burst strength and solids barrier for minimal voids and less clean up..

Conformable, Non-Woven Backing Offers High Air/Gas Permeability
We manufacture 3M™ Vent Tape 394 to meet most typical outgassing requirements for foam-in-place insulation processes in appliance and other industries. The non-woven backing conforms well, providing an effective seal. This unique backing has high air and gas permeability, allowing minimal foaming voids and has good burst strength, which helps reduce clean-up.

Recommended applications

Outgas venting in appliances‎

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 3M™ Vent 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™ Vent Tape 394 keeps foam-in-place insulation inside door and appliance cavities, while helping eliminate voids.
