3M™ SPECIALTY TAPES

Advanced Venting Solution with 3M™ Vent Tape 394

3M™ Vent Tape 394 is a high-performance, single-sided specialty tape engineered for precise outgassing control in foam-in-place insulation processes. Featuring a nonwoven synthetic backing with exceptional air and gas permeability, this tape ensures insulation foam stays in place while allowing gases to escape.

Its conformability, strong burst resistance, and effective barrier against solids make it an ideal choice for applications requiring clean, efficient venting – especially in appliance manufacturing.

Applications for 3M™ Vent Tape 394

Refrigerator and freezer production – cabinet and door insulation
Foam-in-place polyurethane (PUR) processes – venting during injection
Gas release management – appliance cavities, panels, and enclosures
Technical insulation manufacturing – controlling foam expansion
Any industrial process requiring clean air/gas escape during foam fill

Key Benefits of 3M™ Vent Tape 394

High air/gas permeability – minimizes voids and defects in foamed insulation
Nonwoven synthetic backing – flexible, strong, and conformable to irregular surfaces
Pressure-sensitive adhesive (PSA) – bonds well to a variety of surfaces
Reduces foam leakage and cleanup – keeps solid materials in place
Excellent burst strength – withstands expanding pressure during foam fill
