“…The rotomolded Zimbabwean graphite composites showed modest improvements in the Young's moduli up to 10 wt.% graphite content. Previous investigations on the moduli of rotomolded composites also showed an initial improvement, then deterioration thereafter [1,32,36]. The expandable and expanded graphite composites did not show a marked improvement in the modulus.…”

“…Rotational molding, also referred to as rotomolding or rotocasting, is an attractive technique well-suited for the manufacture of hollow parts with complex shapes [1]. Unlike other polymer forming processes, rotomolded products are nearly stress-free.…”

“…Hence the recent interest in expanded graphite and graphite nanoplatelets, as they promise attainment of resistivity at low percolation thresholds [17,26,29,30,31]. However, agglomeration and segregation of particulate fillers is a potential problem in rotomolding [1,[32][33][34].…”

“…One of the great advantages of rotational molding is the low cost and the simplicity of mold, because the molten polymer takes the shape of the mold under very low stresses 1,2 . The principal polymer used in rotational molding is polyethylene, due to its high thermal stability and the wide range of grades developed for this process [3][4][5] . Hafsaoui et al 6 affirm that the principal disadvantage of rotational molding is the relatively long cycle time compared to conventional techniques and they present a thermal model for simulation which permits to follow the local evolution of the temperature in various areas of rotational molding and gives a good representation of experimental data.…”

Influence of calcium carbonate and slip agent addition on linear medium density polyethylene processed by rotational molding

In this paper, the influence of calcium carbonate and slip agent on linear medium density polyethylene (LMDPE) processed by rotational molding was evaluated. LMDPE was dry blended with different CaCO 3 masterbatch ratios, erucamide slip agent and then extruded, micronized and rotomolded. The powder samples were characterized using MFI (Melting flow index), dry flow and bulk density. The characterization of rotomolded samples properties was performed by DSC (Differential scanning calorimetry), microscopy analysis, izod impact and tensile test. The results pointed out that the CaCO 3 addition modifies the bulk density compared to neat LMDPE, but did not significantly affect the dry flow and MFI. The erucamide addition decreased the dry flow and increased the bulk densities. The porosity degree data showed that CaCO 3 addition in the LMDPE increased the quantity of pores. The DSC results showed no significant difference in the crystallinity degree. The behavior of porosity led to a decrease in the mechanical properties of LMDPE with the CaCO 3 addition.

Fillers have played an important role in plastic and composite industries in aspects of traditional material reinforcements with higher modulus and strength, enhancements of multifunctional properties in thermal and/or electrical conductivities, heat distortion temperature, wear resistance and dimensional stability, and so on. Fillers synergistically act as essential constituent in composite materials to achieve many difficult‐to‐attain properties, which are the stringent requirements and specifications when employed for a wide range of end‐user applications. The different types of fillers in terms of two major classifications of organic and inorganic fillers are elaborated in this article with special focuses on naturally extracted fillers for “green composites” and nanofillers for “polymer nanocomposites.” The filler processing methods are also explicitly reviewed, which are based on the conventional plastic molding techniques such as extrusion, injection molding, compression molding, thermoforming, blow molding, and rotational molding. Finally, the commonly used characterization techniques to deal with filler‐reinforced composite materials are summarized in order to understand the processing‐structure‐property relationship due to the contribution of fillers in polymer matrices.
