Ground tire rubber filled low-density polyethylene: The effect of particle size

In the present study, we investigated possibility of value-added recycling ultrafine ground tire rubber (uGTR) produced from water jet milling, with an average particle size a few tens microns. Our goal was to compare properties blends different uGTR and conventional fine (fGTR) contents prepared by blending low-density polyethylene (LDPE). We also aimed explore property changes caused larger specific surface area due effect. Samples were hydraulic press after internal mixing. case (GTR) filled mixtures, tensile showed rubber-like characteristics: significant decrease in modulus, elongation at break remained high, strength slightly decreased. The fracture surfaces samples analyzed scanning electron microscopy (SEM), wherein materials made better adhesion between phases. order investigate interfacial GTR LDPE, performed dynamic mechanical thermal analysis (DMTA). glass transition peak shifted higher temperature storage modulus than containing fGTR. Finally, determined Shore D hardness materials, which decreased increasing content, but greater samples. explained two phases significantly compared
