“…Nowadays, it was found that LDPE waste can be developed if their low mechanical properties can be improved by adding other materials [1,2]. Efforts by various researchers to modify and blend recycled thermoplastic waste have been investigated so as to obtain finished products with good mechanical properties [3,4].…”

Thermoplastic polyolefin (TPO) has gained considerable attention because of having a combination of rubbery and thermoplastic properties and ease of production. Their excellent weather resistance, low density, and relatively low cost make them attractive materials for the automotive, electrical, footwear industries and membranes for water treatment. Their main shortcomings are poor mechanical properties, especially at low temperatures because of the opposing trends of stiffness and toughness. In this paper, recycled low density polyethylene (RLDPE) was integrated with ethylene-propylene-diene rubber (EPDM) incorporating very low content of carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) to improve the mechanical properties of the produced TPO nanocomposite. TPO has been prepared through the combination of 40, 50, and 60 wt.% RLDPE and 40, 50, and 60 wt.% EBDM. The improved TPO composition was then reinforced with 0.1, 0.3, and 0.5 wt.% MWCNTs-COOH to produce TPO nanocomposites. The compounding of TPO and its nanocomposites was done by melt mixing followed by heat pressing. Mechanical and thermal behaviors of the TPO nanocomposites were investigated. Tensile tests showed that the TOP (60-40) is the best improved concentration; the storage modulus of nanocomposites was enhanced by increasing MWCNTs-COOH concentration. In addition, modulus, stress/strain and toughness of TPO were enhanced by adding 0.5 wt.% MWCNTs-COOH. Thus, MWCNTs-COOH reinforced TPO due to not only its large aspect ratios but also due to its interaction with both the TOP matrix and the combatibilizer. The results of microstructural investigations of the prepared TPO nanocomposite using FTIR and TGA confirmed the interaction between MWCNTs-COOH and TPO matrix

Kenaf fibers have been extensively explored from the past few decades in polymer composites industries owing to its extensive adaptations, excellent properties together with its comparable mechanical properties to traditional glass fibers polymer composites. The combustibility or lowered flame retardancy hampered the diverse applications of kenaf fibers reinforced polymer composites, as it affects the mechanical strength and stiffness of composites during fire. Current review article intended to be a comprehensive source of published literature involving the flame retardants (FRs), types and applications of FRs and the fabrication of kenaf fibers reinforced polymer composites. This article will also provide a perfect data on the recent development of the FR kenaf fibers polymer composites with different FRs and explored its structural and semi‐structural industrial application for performing further research in this topic.

The aim of this study was to investigate the effect of combination of magnesium hydroxide (Mg(OH)2) and Multiwall Carbon Nanotubes (MWCNT) on the thermal, flammable, and mechanical properties of ternary blends (High density polyethylene/Low density polyethylene/Nylon). Kenaf fiber has also been added for reinforcement. For ternary blend it is found that the tensile strength value was increased by 50% at 0.5/0.5 wt% loading of Mg(OH)2/MWCNT as compared to composite without filler. The improvement in tensile strength was also significant from scanning electron microscope micrographs and also assessed using predictive theories. The cone calorimeter studies showed lowered peak heat release rate with addition of MWCNT/Mg(OH)2. It also promoted char formation and thus improved flame retardancy of the nanocomposites. These composites have a potential for application as high performance fire retardant composites by recycling mixed plastic waste. POLYM.
