  • Zeon Chemicals LP has developed a new epichlorohydrin (ECO) elastomer called Hydrin DP5245 for use to dampen and absorb vibration or sound while also being resistant to oils, hydrocarbons, ozone, and elevated temperatures. This presentation will explain advantages and weaknesses of current materials, test methods for measuring damping performance, and showcase test data comparing the new Hydrin (ECO) elastomer alongside competitive materials such as Polychloroprene (CR) and Nitrile (NBR). Furthermore, the novel grade of Hydrin is easily made into foam by addition of a blowing agent which makes it ideal for automotive NVH. A study into the foam properties of several elastomers including this new grade of ECO was also performed with a focus on sound and heat insulation. This novel polymer solution is very useful for manufacturing and construction equipment or automotive body panels, for example. When made into support pads or body panel insulation the rubber material will reduce or eliminate vibration or noise transfer to the operator or the surroundings, providing an advance in materials used for vibration and acoustic damping.
