Abstract In this work, the effect of natural (NV) and expanded (EV) vermiculite clays on the properties of biopolyethylene (BioPE)-vermiculite clay biocomposites was investigated. It was observed that the addition of NV and EV clays to BioPE increased the Heat Deflection Temperature (HDT) and improved the fire retardance.

Use of castor and canola oils in “biopolyethylene” curauá fiber composites
Composites Part A: Applied Science and Manufacturing, 2017Abstract High-density biopolyethylene (HDBPE) used as a matrix in composites reinforced by curaua fibers (5, 10, 15 and 20 wt%, 1 cm) was obtained on an industrial scale by polymerization of ethylene derived from sugarcane ethanol. Castor (CO) and canola (CA) oils were used in the preparation of composites (5, 10, 15, and 20 wt%) as a potential ...

Bionanocomposite Obtained from Poly (lactic acid)/Biopolyethylene Blend and Clay
Macromolecular Symposia, 2014SummaryThe aim of this work is the development of a bionanocomposite from Poly (lactic acid)‐PLA/Biopolyethylene (PE) blend and clay. The montmorillonite (MMT) clay was organically modified with an ionic surfactant to become organophilic (OMMT). The MMT and OMMT clays were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and X‐Ray ...

The production of plastic products from non-renewable raw materials, such as petroleum, damages the environment. Consequently, biocomposites have aroused interest from industry and researchers due to their ecologically correct characteristics, mainly because they come from renewable sources. Therefore, this study aimed to produce biopolyethylene/coffee

AbstractLow‐density biopolyethylene (BioLDPE) ecocomposites added with particles of eggshell (ES) residue were produced using linear low‐density polyethylene grafted with maleic anhydride (LDPE‐g‐MA) as a compatibilizing agent. BioLDPE/ES and BioLDPE/ES/LDPE‐g‐MA compounds were processed in a twin‐screw extruder, and the specimens were injection molded.
