Ballistic Sound Dampening Material is an elastomeric butyl and aluminum layered vibration dampener that conforms and fuses easily to sheet metal and other hard surfaces. Ballistic’s super strong adhesive can withstand temperature extremes between -65°F to +300°F (-54°C to 149°C). Ballistic is the ideal product in creating an acoustical barrier between unwanted external noise and vibrations and your desired inter cabin acoustics.
