Blends of LLDPE and LDPE combine the favorable mechanical properties of the LLDPE with the ease of processing of LDPE. Yet, the melt rheological consequences of blending LLDPE and LDPE have received far less attention than have linear/linear or linear/ branched blends (1). Previous reports showed that blends of LLDPE/LDPE were either immiscible or partially miscible (2–5). Considering the compo...

Many road construction and maintenance projects are increasingly using recycled material as pavement material. Most of the times, generic sustainability evaluations ascribed to products without fully considering their performance. The potential environmental benefits various alternatives can be analytically evaluated with Life Cycle Assessment while many performance indicators found through lab...

Linear Low Density Polyethylene-Natural Rubber (LLDPE-NR) composites in the ratio of 70:20 were made with different loadings of nanosilica and micro-scale Palm Oil Fuel Ash (POFA). Linear Low Density Polyethylene grafted with maleic anhydride (LLDPE-g-MAH) of 10 wt% was added as a compatibiliser. The composites were produced by using two-roll mill machine. The tensile properties of the composit...

A highly electrically conductive linear low-density polyethylene/graphene nanoplate composite with segregated structure (s-LLDPE/GN) was prepared by Yongmei Ma and colleagues through an environmentally friendly method. First, GN coated LLDPE granules were aqueous dispersion, gradually drying. SEM images show that has been successfully on the granule surfaces. Then, s-LLDPE/GN composites obtaine...

Straw utilization is a key issue related to agricultural production and air pollution control. In this study, novel extrusion process was proposed improve the physical mechanical properties of straw-reinforced linear low-density polyethylene (LLDPE) composite. Instead crushing straw mixing it with plastic matrix, new method mixes matrix in its original form. The intact long rice straws were par...

Vitrimers are a new class of materials that consist chemically cross-linked networks engage in thermoactivated associative exchange reactions. These reactions can impart malleability, healing, and recyclability properties to thermosets. In this study, one-step protocol prepare linear low-density polyethylene (LLDPE) vitrimer-like with disulfide bonds via reactive blending is presented. The cros...

Magnetically sensitive shape memory poly(styrene-b-butadiene-b-styrene) copolymer (SBS)/liner low density polyethylene (LLDPE) composites filled with various contents of Fe3O4 nanoparticles were prepared. The influence of the Fe3O4 nanoparticles content on the thermal properties, mechanical properties, fracture morphology, magnetic behavior, and shape memory effect of SBS/LLDPE/Fe3O4 composites...

پلی‌اتیلن کم‌چگالی خطی (LLDPE) پلیمری خطی با تعداد قابل توجهی شاخه جانبی کوتاه است که معمولاً از کوپلیمر‌شدن اتیلن با اولفین‌هایی مانند 1-بوتن، 1-هگزن و 1-اُکتن تهیه می‌شود. LLDPE در مقایسه با پلی‌اتیلن کم‌چگالی (LDPE)، دارای استحکام کششی، مقاومت ضربه‌ای و مقاومت سوراخ‌شدگی بیشتری است. این پلیمر به‌دلیل ترکیبی از نرمی و مقاومت در برابر تنش به‌طور گسترده به‌عنوان پلیمر گرمانرم استفاده می‌شود. همچن...
