Not specified noise absorber STRASONIC®

Description
STRASONIC® is a multilayer acoustic protective foam composed of a 100% waterproof black PU film bonded to a 25 mm heavy-weight (5 kg/m2) corrugated PU ether absorption foam, itself bonded to a 3 mm spring foam. It is designed to reduce airborne noise (isolation, absorption and damping) in partial or complete machine enclosures.

Advantages
