Hydrin-brand ECO has a long history of use in automotive applications due its exceptional heat and oil resistance up to 150°C, while maintaining flexibility at low temperatures down to -50°C. While mainly used in air and fuel hose applications, the elastomer also possesses unique properties for vibration and acoustic damping. Standard grades, such as Hydrin T3108, offer an upgrade over commonly used polychloroprene in terms of heat and oil resistance, and data is shown where comparable damping response is achieved across a wide temperature range.
Furthermore, a newly developed commercial product, Hydrin DP5245, further improves these dynamic properties and provides the rubber industry with a new option when ultra-high damping at normal temperatures is desired. Hydrin DP5245 also is easily foamed for use as lightweight acoustic insulation or sound baffling.
Data is shown for Hydrin and competitive materials for both solid and foamed samples in a multitude of tests which illustrate the exceptional damping performance of Hydrin DP5245, as well as Hydrin polymers’ resistance to heat and oil in harsh environments.
