General Description

SoundX® solutions provide customers with a flexible sheet for sound abatement applications.

It has excellent cold temperature flexibility and is perfect for low to medium draw, thermoformed engine and firewall partitions. Additionally, SoundX® EVA can be easily compression molded or die cut to fit most sound abatement applications.
