Industrial-grade pink venting tape with non-woven backing for foam-in-place insulation applications. Features high air/gas permeability, strip-coated acrylic adhesive, and meets outgassing requirements for appliance manufacturing.
3M™ Venting Tape 3294 is a specialized pink non-woven synthetic backing tape with strip-coated low-tack pressure sensitive acrylic adhesive designed for high-performance venting applications. This industrial-grade tape features unique air and gas permeability properties that make it ideal for foam-in-place insulation processes in appliance manufacturing, particularly for refrigerators and freezers. The conformable non-woven backing allows air and gases to escape while keeping foam solids in place, effectively reducing foaming voids and minimizing cleanup requirements.
The tape's innovative strip-coated adhesive design ensures that uncoated areas maintain higher permeability, which is critical for preventing void formation during the insulation process. With dimensions of 2 inches wide by 36 yards long and a total thickness of 5 mil, this tape meets stringent outgassing requirements and complies with ASTM D3330, ASTM D3652, and ASTM D3759 specifications. Each case contains 24 rolls, providing substantial coverage for large-scale manufacturing operations.
Manufactured by 3M's Industrial Adhesives and Tape Division, this venting tape represents the company's commitment to applying adhesion science to deliver innovative solutions that improve design and manufacturing processes. The product is specifically engineered for industrial and occupational use in appliance manufacturing environments where reliable foam venting is essential for product quality and manufacturing efficiency.
