Rockville Sound Deadening Melted in Packaging Failure
In the submitted examples shown, Rockville sound deadening appears to have arrived
already melted inside its own packaging. The butyl had already turned into a goopy
mess before the material was ever installed, and the product had to be thrown out
immediately.
That is a severe failure. A CLD product should be able to survive normal storage,
handling, and shipping without arriving in this condition. When the butyl is already
melted and unstable right out of the package, the product is already showing that the
formula is far too poor for reliable use as an effective constrained layer damper for
resonance reduction.
Based on what is shown here, the most likely cause is a very poor butyl formula. This is the first time I was able see photo evidence of Rockville failing this way, though I have heard of a few other issues in the past. From a functional standpoint, this is already a failure. If the material cannot even handle being shipped without turning into goop, that tells you plenty about the quality and stability of the formula.
