GENERAL INFORMATION

4014 is a 25mil, open cell polyurethane foam tape, primarily used for plastic or metal contact with materials that can result in potentially damaging vibration. It has an aluminum constraining layer on one side and a pressure sensitive adhesive on the opposite side to facilitate attachment to the surface of the vibrating panel. The adhesive is protected by an easy-release liner.

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.
