Keldax® Sound-Barrier Resins

Nothing says luxury like the pristine hush of a well-insulated car interior. DuPont™ Keldax® sound-barrier resins in carpet backing, door panels and components help reduce unwanted noise, from both interior sources, such as seat belt retractors, and exterior culprits, like engines, transmissions, and suspension systems. A recyclable thermoplastic, Keldax® can be molded to extremely thin gauges, a critical advantage when designing double-walled sound barriers, which include a sound-deadening air space.
