Abstract :

      One of the ways to improve the mechanical properties and product new compounds with good quality is the use of combination of polymer and thermoplastic elastomers. In addition to the use of nano clay particles can affect the properties of polymer composites. One of the most renowned elastomers is nitrile butadiene rubber (NBR). The thermoplastic elastomer NBR / PP is applied for oil resistance and high temperature. Therefore, in this paper are discussed the recovery characteristics of thermoplastic elastomer NBR / PP with the addition of clay nanoparticles. By a laboratory mixer, ratios of 2, 3 and 5 wt% nano clay particles with thermoplastic elastomer NBR / PP was mixed. The results of the profile of the structure using X-ray diffraction (XRD) showed that the formation of flake structure, the clay is used in related samples. The results of nanocomposite structural effect on mechanical properties such as tensile strength, stretch to the point of rupture, hardness and thermal analysis TGA and DTA for each of the samples were studied.
