Abstract

Indonesia is a second largest rubber-producing countries in the world with production of 3.18 million tons in 2013, after Thailand, and has a land area of the world's largest rubber plantation with an area of 3.56 million hectares in 2013. So the rubber and rubber goods are commodities that are very important and influential on the national economy. One of widely used product of the rubber is a sponge for floating media. The sponge is made of not only synthetic rubber, but also natural rubber. In this research, DPNR was used as a raw material rubber to produce sponge of floating hose. The results showed that sponges are made of DPNR3 has a density of 0.1890 g/cm3, compression set at room temperature of 8.08%, and 19.11% at a temperature of 700C, while the original (DPNR1) has a density of 0.3018g/cm3, 25.33% of compression set at room temperature, and 27.30% at a temperature of 70 ̊C. DPNR3 rubber can be used as raw material for the manufacture of sponges because the sponges which are obtained meet the technical specification requirements.
