Evaluation of the effect of clay nanoparticles on mechanical properties of recycled polyethylene

Recycled film blowing extrusion grade polyethylene (rPE) was studied by investigating an influence of organically-modified nanoclay (montmorillonite) on the mechanical properties. In this paper, recycled film composite blowing extrusion grade polyethylene was studied as variations of mechanical properties. Consequently, a surface modified clay nanoparticle with melt intercalation method vs. changing in nanoclay content in polymer matrix was studied. In this work, the tensile modulus, tensile strength, elongation at yield, impact strength, surface hardness and MFI are measured for determination mechanical properties. Experimental results of recycled polyethylene showed that with increased clay ratio, Chain entanglement and chain mobility decreased and brittleness increased and decreased plastic behavior
