Abstract: | Natural rubber obtained from a milky colloid (latex) extras mainly from the tree Hevea Brasiliensis is approximately 95% cis-polyisopren has important physical properties. Among its shortcomings are resistance to aging and thermal stability that limits its applications. The use of fillers in rubber is almost as old as the use of rubber itself. ZnO originally used for whiteness was the first “active” filler. In 1904 carbon black was discovered and since then became the most important powder used in rubber technology. Recently various mineral and organic nanoparticles are studied as reinforcements for elastomers in view -with minimum amounts – to achieve required properties. Natural rubber nanocomposites bring together mechanical and thermal properties from the rubber matrix and special characteristics of the nanoparticles. |
