“…Previously, thermogravimetric analysis of plastic waste used for the manufacturing WPC samples showed that about 2 to 8 wt% of solid ash was at the residue, whereas the reference from pristine PE burned completely. 10 The same tendency was described by Kwak and Nam 5 when they studied the fire resistance of PP-based recycled composites. 5…”

“…In the present case, a possible reason for the diminishing of the anti‐flammable properties of CB was poor dispersion of CB particles through the matrix. As proposed in our previous work, due to the heterogeneity of the matrix and incompatibility between PP and PE, CB particles could accumulate in the PE/PP separation phase . The ignition time for the CB‐containing sample decreased compared to its “precursor,” PB_C4.…”

“…Carbon black, Raven®1170, was delivered by IMCD Finland Oy, mean particle size 21 nm, surface area 107 m 2 /g. The recycled plastic sources were household and construction solid waste described previously . Briefly, PB_C1‐PB_C8 were manufactured by using a “light fraction” (PE and PP) extracted from a construction mixed plastic blend; PB_C9 was manufactured from mixed household plastic waste.…”

“…The recycled plastic sources were household and construction solid waste described previously. 9,10 Briefly, PB_C1-PB_C8 were manufactured by using a "light fraction" (PE and PP) extracted from a construction mixed plastic blend; PB_C9 was manufactured from mixed household plastic waste. The composition of the matrix, the PE percentage, was identified with calibration by using Fourier transform infrared analysis and is shown in Table 1.…”

Summary The flammability of wood plastic composites manufactured from recycled plastics was investigated by using the cone calorimetry technique. The peak of the heat release rate was 12% to 25% lower compared to references produced from pure polyethylene‐ and polypropylene‐based composites. The total heat capacity and mass loss rate were also smaller for recycled material compared to the references. The stability of the composites was improved due to the presence of various thermally stable compounds, eg, traces of fire retardants, pigments, and other additives and impurities that can be present in recycled material. Incorporation of carbon black into the secondary materials did not reduce the peak of the heat release rate, but the total heat capacity and mass loss rate decreased further.

Recycled plastic (rHDPE) was coupled with different weight percentage of ronier palm leaf fiber (RLFs) to prepare eco‐friendly polymer biocomposites. Fourier transform infrared analysis, tensile test, dynamic rheological test, hardness test, scanning electron microscopy (SEM) analysis, and density measurement were used to determine the structural, mechanical, morphological and physical properties of the biocomposites. The modulus showed excellent improvement with the addition of RLFs. G′ and G″ were found to increase with the increment of both the filler content and the angular frequency. At low frequencies, the loss factor was increased with the frequency and decreased with the RLFs content. However, at high frequencies, it was decreased with both the angular frequency and the RLFs content. The complex viscosity η* was found to be increasing and decreasing with the RLFs content and the angular frequency, respectively. SEM micrographs of tensile fractured surfaces of biocomposites show pulled out RLFs zones and voids due to the presence of agglomeration. Finally, the experimental Young's modulus data was compared with theoretical predictions. A good fit was obtained with Einstein Model.
