Abstract;Rubbers are often used outdoors or indoor locations where they are exposed to daylight or to daylight behind glass for long periods. It is therefore very important to determine the effects of daylight, heat, moisture and other climatic stresses on the color and other properties of rubbers. In this investigation the effects of Ultra Violet (UV) light on the properties of rubber bushing are studied. The rubber-bushing specimen was received from manufacturer in the form of flat sheet specimen with uniform thickness of 5mm. The specimens were exposed to type I Fluorescent UV lamp with radiant emission of 340nm for 100 hours. Standard ISO 4892-3: 1994 was employed during the experiment. As outlined by standard, the exposure is programmed by cycling through four hour periods of dry UV exposure at black-standard temperature of 60.DEG.C..+-.3.DEG.C., followed by four hour periods of condensation exposure with no radiation at a black-standard temperature of 50.DEG.C..+-.3.DEG.C.. After the exposure the specimen were visually inspected for cracks, warping, fungus, mildew followed by microstructure observation using scanning electron microscope (SEM). The results showed no substantial crack, warping, fungus and mildew were observed on specimens. Oxidation was observed on the exposed surface, which is showed by darker color than the original. Fourrier Transform Infra Red (FTIR) was also employed to investigate the changes in molecular interaction before and after the exposure. The showed that after the exposure, the double bound of the butadiene rubber was degraded which is indicated by disappearance its peak. (author abst.)
