Polyethylene/Cloisite 20A Nanocomposites with Improved Mechanical and Thermal Properties for Preparation of Natural Gas Transportation Pipes

Intercalated polyethylene/Cloisite 20A nanocomposites were prepared with different loadings of closite20A (0, 1, 3 and 5 wt%) via melt blending. The mechanical and thermal properties of prepared nanocomposites were investigated by the tensile, DSC and MFI tests. The results demonstrated the improved mechanical properties (i.e. tensile strength, Young’s modulus and yields stress) and also increased melting temperature and decreased MFI for nanocomposites compared with the pure polyethylene
