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.
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.
