NR vulcanizate has its unigue characteristic of cushion, silence, vibration energy absorbtion etc. By reason of the above captioned characters, The vulcanizate has been widely applied to production of auto tires, belts and engine mounts, The purpose of this study is to examine the effect of rubber-filler attachments on the various dynamic properties of the NR vulcanizates. For this study, the elastic modulus and damping values are examined by means of the (RDS) the Good Rich Flexometer. The results of this study showed as follows. The damping values of the vulcaniz ates in the elastic region showed showed strong relations the damping values and the filler characteristics. The vulvanizates filled with carbon black had higher damping values than the vulcanizates loaded with inorganic filler. The Goodrich Flexometer test showed that build up for the silica filled NR vulcanizates was higher than those for which contained other fillers.
