Deadening Sheet (Vibration Dampening Material) Approximately 10cm x Approximately 5cm, Approximately 2.5mm 80 sheets + α (a few sheets with irregular sizes) Vibration Dampening Type Since it's an adhesive butyl tape, you can use it immediately after peeling off the backing paper. Easy-to-use size, perfect for point vibration dampening. Can be cut with scissors, allowing you to work according to the installation location. Applying it to the back of speakers, inside doors, and the trunk room will suppress surrounding rattling noises and road noise from outside the car, bringing you closer to a higher-grade in-car environment. Recommended for those who are thinking of trying deadening for the first time. ※ Please wear gloves when working, as there is a possibility of cutting your hands on the edges of the sheets. Vibration dampening sheets absorb vibrational energy and significantly reduce the transmission of sound and vibration. By applying them to vibrating parts such as metal or resin surfaces that are the cause of the problem, unpleasant noises such as "rattling sounds" and "warbling sounds" are significantly reduced. Because it is an adhesive type, no adhesive is required and processing is easy. ※ Be sure to degrease and remove dust before installation. This is a black butyl tape type, which has stronger adhesion compared to white butyl tape. Therefore, it has high adhesion to the installation location and deadening effects can be expected. Due to product availability, specifications may vary, but there is no effect on the effectiveness, so please rest assured. We also accept changes in the number of sheets, so feel free to comment.
