In this study, acrylonitrile butadiene styrene polymer was exposed to 12 injection cycles to investigate the influence of recycling number on the mechanical, rheological, and morphological properties. Also, binary and ternary blends including different weight percentages and recycling number of virgin–recycled polymers were prepared. A slight decrement was found in the tensile strength values with recycling number. All blends including recycled polymer (binary or ternary) gave lower tensile strength values with respect to 100% virgin polymer. Strain at break value was decreased after twelve times recycling; however, no clear tendency was observed with the presence of different ratios of virgin polymer to recycled polymer. Impact strength of the polymer decreased with recycling number. There was relatively large drop in the third recycling, from 72 kJ/m2 to 38.5 kJ/m2; however, further recycling induced in a slower drop in the impact strength to 32.5 kJ/m2. All blends including recycled material gave lower impact strength values as compared to 100% virgin polymer. It was observed that the melt flow index values increased with the recycling number, a total of 26.53% after twelve times recycling. All blends containing recycled material showed higher melt flow index values as compared to 100% virgin polymer.

Melt Flow

This research is to identify the difference in melt flow and mechanical properties in hybrid composites between kenaf and rice husk that each of the filler was compounded with composite material of calcium carbonate (CaCO3) and high density polyethylene (HDPE) in different loading amount. Different filler loading up to 30 parts of kenaf fibers and rice husk particulate were mixed with the fixed 30% amount of CaCO3. Compounded hybrid composite were prepared and tested for melt flow index, tensile and impact strength. Addition of both fillers had decreased melt flow index (MFI). MFI of rice husk/CaCO3 was higher than kenaf/CaCO3 in HDPE composites. Tensile strength, elongation at break and impact properties of both hybrid composites had decreased with increasing filler content. Tensile strength of kenaf/CaCO3 was higher than rice husk/CaCO3 due to intrinsic fiber structure of kenaf which has some reinforcing effect compared to rice husk. While, impact strength of rice husk/CaCO3 was improved with addition of filler but drastically decrease as the rice husk content were increased up to 30% due to high silica content in rice husk. The Youngs Modulus was increased with addition of natural fibers in CaCO3/HDPE composite.

The recyclability of polystyrene, acrylonitrile butadiene styrene and polyvinylchloride waste and their use as a source for 3D printing were studied. Filaments of about 3 mm in diameter were extruded successfully with a small-size extruder. The processed filaments were tested on a broad range of parameters-melt flow index, glass transition temperature, tensile properties and a pyrolysis scenario were obtained. The measured parameters were compared with parameters of virgin counterparts presented in the literature. In order to estimate the composition of the recycled material, Fourier Transform Infrared and elemental analysis of the samples was done.

In this study, the ageing behaviour of glass-fibre-reinforced poly(oxymethylene) composite at different conditions was investigated. The ageing was performed in various controlled environments, namely in air at room temperature, in water at room temperature and in an oven at the temperature of 100 ℃. Tensile and flexural tests were conducted to determine the mechanical properties, melt flow index was measured to determine the rheological property and scanning electron microscopy was used to observe the morphological property of unaged and aged poly(oxymethylene) samples. A reduction in both tensile and flexural strength was observed with all ageing environment. The worst strength retention was obtained with water ageing. Water absorbed by glass-fibre-reinforced poly(oxymethylene) composite had a detrimental influence on the tensile and flexural strength. Tensile strength was affected by the ageing environments. The decrease in the tensile strength of air and thermally aged poly(oxymethylene) was slower than that of water aged poly(oxymethylene), and the tensile strength of aged samples decreased as the ageing time increased. The combined actions of heat, air and water (thermal + water + air ageing) did not further degrade glass-fibre-reinforced poly(oxymethylene) compared to only water ageing at the room temperature. All tensile stress–strain and flexural load–deflection curves showed the similar tendency and did not change with ageing environments and time. All aged samples showed higher melt flow index values than that of unaged sample and the changes in melt flow index could be an indicator of degradation.

The effects of two types of carbon nanotubes, namely multiwall (MWCNT) and single-wall (SWCNT) carbon nanotube, on the thermal and mechanical properties of acrylonitrile-butadiene-styrene (ABS) nanocomposites, have been investigated. ABS filled-CNT nanocomposites with various filler loadings of 5–10 wt% were properly produced by a solvent-free process in blend compounding at 190 °C. Compression moulded plates and extruded filaments were obtained at 190 °C and 230 °C, respectively. Melt flow index (MFI), shore hardness, Vicat temperature, differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) were performed to characterize and compared the different CNT nanocomposites. ABS/SWCNT composite filaments showed higher tensile properties (i.e., stiffness and strength), than ABS/MWCNT. The electrical resistivity of ABS/SWCNT and ABS/MWCNT filaments decreased to 0.19 Ω.cm and 0.65 Ω.cm for nanocomposites with 10 wt% of nanofillers; a power law was presented to describe the electrical resistivity of composites as a function of the CNTs content. A final comparative parameter regarding melt flow, stiffness and conductivity was also evaluated for understanding the combined effects of the nanofillers. SWCNT nanocomposites exhibited better overall cumulative results than MWCNT nanocomposites.

Polyolefin Elastomer

To develop filled polymer compositions based on polypropylene with different contents of calcite concentrate as a filler and the newest polyolefin elastomer as a modifier; to define the influence of the compositions on their rheological and physico-mechanical properties for production injection molded goods. The values of viscosity, melt flow index, tensile strength, elongation, and impact strength and frost resistance of the compositions depending on their composition are determined by standard methods. The influence of calcite concentrate as a filler and polyolefin elastomer as a modifier on the rheological and mechanical properties of compositions has been determined. With an increase in the amount of filler the physical and mechanical properties of the filled compositions are reduce that is offset by introducing the newest polyolefin elastomer as a modifier in amount of 5 wt. %. Addition of 5 wt. % of polyolefin elastomer in the filled composition gives them frost resistance, wherein the impact strength is higher than for compositions without the modifier even after freezing for 30 days at -18°С. It has been determined that adding of the filler does not increase the viscosity of the compositions, which contradicts the traditional behavior of filled systems. The addition of 5 wt. % of polyolefin elastomer to the filled compositions with calcite concentrate up to 20 wt.% does not change the tensile strength of the compositions which is 24 MPa, but increases elongation by 2 times, impact strength by an average of 8,5 % and frost resistance after freezing compositions at -18 °C for 30 days by an average of 12,6 %. The research results of rheological and physic-mechanical properties allow choosing the rational composition to achieve the desired characteristics of the polymer material for production goods by injection molding. Melt flow index of the compositions increases with increasing amount of filler to 50 wt. %. which does not increase the production costs of the injection molding process in comparison with unfilled compositions.

The effects of styrene-co-maleic anhydride (SMA) compatibilizer on the mechanical thermal and morphological properties of polyoxymethylene (POM)/acrylonitrile-butadiene-styrene (ABS) blends were inverstigated. POM/ABS blends without and with SMA compatibilizer were prepared by an internal mixer and molded by compression molding. It was found that the dispersion of ABS phase and compatibility could not improve by using SMA compatibilizer in POM/ABS blends due to SMA can be miscible with ABS phase more than POM phase. The addition of ABS in a range of 10-30 wt% could improve the Young’s modulus of POM. Impact strength, tensile strength and percent strain at break of POM/ABS blends decreased with increasing ABS content. The addition of compatibilizer improved Young’s modulus of POM/ABS (60/40, 50/50) blends. The addition of ABS increased the degradation temperature of POM, while SMA compatibilizer did not improve the degradation of POM/ABS blends.

AbstractChopped jute fiber (JF) surfaces were modified using alkaline, silane and eco-grade epoxy resin. Surface characteristics of jute fibers were confirmed by FTIR and EDX analyses. JF filled polyurethane elastomer (TPU) composites were prepared via extrusion process. The effect of surface modifications of JF on mechanical, thermo-mechanical, melt-flow, water uptake and morphological properties of TPU-based eco-composites were investigated by tensile and hardness tests, dynamic mechanical analysis (DMA), melt flow index (MFI) test, water absorption measurements and scanning electron microscopy (SEM) techniques, respectively. Mechanical test results showed that silane and epoxy treated JF additions led to increase in tensile strength, modulus and hardness of TPU. Glass transition temperature (Tg) of TPU rose up to higher values after JF inclusions regardless of treatment type. Si-JF filled TPU exhibited the lowest water absorption among composites. Surface treated JFs displayed homogeneous dispersion into TPU and their surface were covered by TPU according to SEM micro-photographs.

The present investigation deals with the viability of the use of recycled milk pouch material, which is a 50:50 mixture of LDPE and LLDPE, and the scope for improvement of its properties by combining it with virgin LDPE-LLDPE (50/50). Melt flow index (MFI), rheological properties, thermal and mechanical properties of the pure materials and their formulated blends containing recycled milk pouches were studied. The properties of the recycled materials were not as satisfactory as those of the corresponding virgin materials. But a significant improvement in viscosity, crystallinity, tensile strength and elongation at break of the recycled LDPE-LLDPE material was achieved by blending it with the corresponding virgin LDPE-LLDPE blend.
