Abstract In this study, we evaluate the thermal and mechanical properties of materials based on polypropylene (PP), high-density polyethylene (HDPE), terephthalate (PET) using thermogravimetric analysis impulse excitation technique. The results show that even if melted input material together with pressure ~4 MPa was used to produce samples, can find small cavities around sand grains in samples...
Increasing end-of-life material recovery and its application in new products is essential to reduce resource consumption. This paper assesses the cradle-to-gate life cycle energy carbon dioxide (CO2) emissions of a road safety barrier product be installed around guardrails’ poles. To analyze potential benefit incorporating recycled materials, base case A, produced with conventional virgin synt...
We report the design, synthesis, morphology, phase behavior, and mechanical properties of semicrystalline, polyolefin-based block copolymers. By using living, stereoselective insertion polymerization catalysts, syndiotactic polypropylene-block-poly(ethylene-co-propylene)-block-syndiotactic polypropylene and isotactic polypropylene-block-regioirregular polypropylene-block-isotactic polypropylene...
In this work, a complete sorting and characterization of dirty non-recyclable mixed plastic (plasmix fraction) from municipal solid waste was performed. The procedure comprised visual inspection identification the materials presented in bales, subsequent moisture dirt content determination. Afterwards, both polypropylene polystyrene fractions obtained process were recycled physico-mechanically ...
In this study, we investigated the rejection of the synthetic patch and human tissues in the host. We observed the growth of adipose-derived stem cells (ADSCs) cultured with polypropylene mesh in vitro. The results of flow cytometry showed that the expression of CD44, CD73, CD90, CD45, CD14 and CD34 was 98.54, 95.32, 98.49, 1.21, 3.01 and 2.14%, respectively. ADSCs were isolated from rabbit sub...
