Vent Tape

General Information
3294 is a 5 mil rayon which is a non-woven, synthetic backing with a strip-coated low tack pressure sensitive adhesive for use in various venting applications to allow the confinement and outgassing of foam insulation. The non-woven backing conforms for effective sealing. It allows high air/gas permeability to promote minimal foaming voids. It has good burst strength and the uncoated areas have higher permeability.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.

Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.

Choose the surface energy of the exact surface that the adhesive will contact (e.g. if the part was painted metal, paint would be the surface energy).
