ResoNix CCF Decoupler 7S Tape – Self-adhering sound deadening foam to isolate panels to prevent rattles.


       ResoNix CCF Decoupler 7S Tape is a 6.5mm (+/- 0.5mm) thick closed-cell foam, often referred to as CCF, or sound deadening foam for cars, that is formed into a 1-inch wide and 20-foot long roll. It is used to decouple one panel from another. CCF7S Tape features an automotive-grade adhesive that makes it easy to install and ensures a lifetime-lasting hold.

       The primary purpose of CCF7 is to prevent audible rattles caused by two panels vibrating against each other. It also reduces the amount of energy transferred from the body of the vehicle to your noise barrier, making the noise barrier more effective. This works by providing a soft, compliant substrate for the panels to transfer their energy into, rather than vibrating against a hard surface. Essentially, the closed-cell foam provides a cushion of support between vibrating panels.

       CCF sound deadening foam should be used to eliminate panel-on-panel vibration noise in areas such as doors/door panels, rear decks, and various interior panels, as they are the main offenders of this type of noise. When doing aftermarket speaker installs, constrained layer damping alone may not be sufficient to achieve the desired results, as it does not decouple panels.

What makes ResoNix CCF Decoupler 7S and our other sound deadening foams better than other CCF’s available from other providers?

       We have designed our closed-cell foam to have the ideal properties to provide the best decoupling layer in the industry. We have found the perfect balance of providing a thick enough, yet soft enough material to properly decouple panels, while also being easy to work with due to its natural compliance. To get more technical, our foam was picked due to its ideal Compression Deflection and Compression Set parameters. The adhesive we use can easily handle the automotive environment without fail.

       Note: Since the release of our Fiber Mat 25 and Fiber Mat 45, we only recommend using CCF7 for decoupling small areas where the Fiber Mat products cannot fit. For areas where you can fit Fiber Mat, it will be better than CCF7.
