A whole feather-mass system in one product?

Odenwald-Chemie provides the solution! The sound-insulating element Monolayer spring-mass system - O.C.-PREN SC. Our new product O.C.-PREN SC is a foam coated only one side with a special impregnation. It creates a heavy and a lightweight layer which are inextricably bonded in one basic material. This material compound can be used as a lightweight alternative to conventional spring-mass systems (heavy foils back-foamed with PUR-foam) providing the same acoustical characteristics at far lower costs! Due to this innovation, Odenwald has been able to enhance its product portfolio. In addition, it reduces the energy consumption during the manufacturing process as well as the materials requirement, the waste stream and the transport costs.

O.C.-PREN SC meets the requirements for the application in passenger compartments of commercial vehicles, it is resistant to hydrolysis and it complies with the requirements for fire behavior according to FMVSS 302. O.C.-PREN SC allows a very flexible application, as it can be combined with a wide range of adhesives, protective films and cover fleeces.
