GENERAL INFORMATION

A 17.5 mil. pressure-sensitive rubber adhesive tape, coated on a dead soft aluminum foil backing used for application to panels and steel support member for vibration damping purposes. The combination of viscoelastic polymer (type 830 adhesive) and an aluminum foil backing (a constrained layer damper, or CLD) has proved to be a unique construction with exceptional ability to resonant vibrations in the temperature range of -76°Fto 68°F at 100 Hz, plus, higher temperatures at higher frequencies. See 3M data sheet for Dynamic Mechanical Properties of ISD 830 Viscoelastic Adhesive chart.

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.
