Abstract

Polymer's roof has been done using solid waste in rubber gloves industry with the best mixing composition from the making of polymer's roof Samples from any composition which is done thus being pressed by hot compressor with temperature 150° celcius during 30 minutes. After providing samples, examining the physical and mechanical properties, include testing the surface of SEM, DSC, DTA, absorption from XRD, and sound dumping. The results shows that an addition of rubber waste causes the absorption and porosity decreasing, while flexural strength and impact increasing. The result from DSC and DTA shows that samples have an endurance from 300-470° celcius, while SEM shows that the shape of surface from some samples are less homogeneous. The result from absorption using XRD seems that samples absorp as another samples, which is the more addition of rubber waste, the intencity of absorption bigger. From the sound dumping test by thick of samples about 5 x 10·3 meters producing the sound dumping to the average samples with a= 0,128. From the result above, polymer's roof is so suitable with physical and mechanical properties which is needed by the standard polymer's roof.
