434 Aluminum Foil Tape


3M™ 434 Vibration Damping Tape is a low temperature 3M™ Viscoelastic Damping Polymers Type 830 adhesive coated on a dead soft aluminum foil constraining layer. They have pressure sensitive properties and are furnished in roll form and designed for direct, pressure sensitive application to metal and composite panels for vibration damping purposes. The combination of the low temperature 3M viscoelastic polymers type 830 adhesive and an aluminum constraining layer has proven to be an unique construction with exceptional ability to damp resonant vibrations in the temperature range of -76º to +68ºF (-60º to +20ºC). Meets F.A.R. 25.853(a)

Comes with a blue polyethylene liner standard.
