The effect of isophathalic acid-maleic anhydride (IAMA) as a compatibilizer on the tensile properties and swelling behavior of ethylene vinyl acetate /natural rubber/ feldspar (EVA/NR/PF) composites were studied. The EVA/NR/PF composites with and without IAMA were prepared using Brabender Plasticoder at 160oC with 50rpm rotor speed. The results indicated that EVA/NR/PF/IAMA showed higher value of tensile strength and M100 but lower elongation at break and percentage mass swell compared to EVA/NR/PF composites.

The EVA/NR/PF composites with and without IAMA were prepared using Brabender Plasticoder at 160oC with 50rpm rotor speed. The effects of potash feldspar loading and isophathalic acid-maleic anhydride (IAMA) on the tensile properties and morphology analysis of EVA/NR/PF composites were studied. The results indicated that tensile strength for EVA/NR/PF and EVA/NR/PFIAMA composites decreased but M100 increased as the filler loading increased. EVA/NR/PFIAMA composites showed higher value of tensile strength and M100.

Elongation At Break

The effect of irradiation on the mechanical properties of Epoxidized Natural Rubber/Ethylene Vinyl Acetate/Carbon Nanotubes (ENR/EVA/CNTs) nanocomposites were investigated. CNTs at various amount (2, 3, 4 and 6 wt%) were incorporated into ENR50 by solvent casting method. The ENR/CNTs were then blended with EVA by mixing in a Brabender Plasticoder at 120°C. Next, the samples were irradiated by using electron beam with 3 MeV electron beam machine in a dose range of 50 to 200 kGy. The mechanical properties such as tensile strength (Ts), modulus at 100% elongation (M100), elongation at break (Eb) and hardness of reinforced ENR/EVA/CNTs nanocomposites were studied as a function of radiation dose. It was found that, the Ts and M100 has increased almost 2 times compared to the nanocomposites without irradiation up to 150 kGy dose of radiation, and a downward trend thereafter. Gel fraction further confirmed the powerful energy of electron beam radiation result in irradiation-induced crosslinking and further enhanced mechanical properties of the nanocomposites.

The results indicated that EVA/NR/FP/PEgMAH had higher value of tensile strength and M100 but lower elongation at break and percentage mass swell.
