The effects of different sizes of Batu Reput (Dolomite) filler which are smaller size (<63μm) and bigger size (75-150μm) on tensile and morphological properties of Batu Reput (Dolomite) filled SMR L and epoxidized natural rubber (ENR-50) blends were investigated. Results indicated that, the tensile properties, such as tensile strength (TS), elongation at break (Eb) and stress at 100% elongation (M100) of Batu Reput (Dolomite) filled SMR L higher than Batu Reput (Dolomite) filled ENR-50 blends, particularly, at 15 phr of smaller size of Batu Reput (Dolomite). The scanning electron microscopy studies proved, Batu Reput (Dolomite) filled SMR L illustrated a higher Batu Reput (Dolomite) - SMR L matrix interaction compared with Batu Reput (Dolomite) filled ENR-50.

The virgin polyethylene (vPE) and recycled polyethylene (rPE) was melt blended with ethylene propylene diene terpolymer (EPDM) in different ratio by using a Haake Rheomix at 180°C and 50 rpm were prepared. The characterization such as tensile properties and morphology were examined. Results indicated that, the tensile strength and youngs modulus of vPE/rPE/EPDM with CB show the highest value compared to silica and CaCO3 except for elongation at break. The scanning electron microscopy (SEM) studies proved that, better dispersion and less agglomeration of CB and silica filled particles as compared to the CaCO3.

The polymer blend was prepared from natural rubber (NR) and polyethylene (PE) powder blended with epoxidized natural rubber (ENR) by using an internal mixer. In this study, epoxidized natural rubber (ENR) was used as compatibilizer for the blends. Blending ENR with PE powder and NR were prepared at various compositions from 0-20% by weight. Then, specimens from the blends were produced by compression molding at 150 °C. The mechanical and morphological properties of the composites were investigated. It was found that the addition of ENR content has improved the tensile strength, compression set and hardness for the ternary compositions composed of NR/PE powder/ENR compared to the binary one (i.e. NR/PE powder). ENR contributed to a better dispersion between the NR and PE phases as observed in the scanning electron microscopy.

Polypropylene/Cocoa Pod Husk (PP/CPH) biocomposites with different maleated polypropylene (MAPP) content were prepared via melt blending process using Brabender Plastrograph mixer. The tensile strength and tensile modulus of PP/CPH biocomposites increased with increasing of MAPP content. The PP/CPH biocomposites with 5 phr of MAPP showed the optimum improvement on tensile properties. However, the increased of MAPP content reduced the elongation at break of PP/CPH biocomposites. At 5 phr of MAPP content, PP/CPH biocomposites showed lowest elongation at break. Scanning electron microscope confirms the PP/CPH biocomposites with MAPP have better filler-matrix interaction and adhesion due to the effect of MAPP.

Sodium alginate based films containing turmeric oil (TEO) at different concentrations (1, 2 and 3%) were developed. The film with no TEO was used as control. Incorporation of TEO had the effects on the film properties. With increasing TEO concentrations, thickness, elongation at break, permeability of oxygen and water vapor of the films significantly (p ≤ 0.05) increased. Whereas moisture content, tensile strength and modulus of elasticity significantly (p ≤ 0.05) decreased. Scanning electron microscopy (SEM) analysis showed more numerous pores and rougher surface of the antifungal films than the control film.

Nanocellulose (NCC) is incorporated into nitrile butadiene rubber (NBR) latex with the composition 0 to 5 phr using dipping method. Mechanical properties of NBR/NCC composites using tensile test was used to characterize their mechanical performance and the fracture surfaces post tensile test were studied. The tensile strength of NBR/NCC composites increase significantly with the addition of nanocellulose. This could be anticipated due to the presence of Van der Waals interaction between hydrophilic natures of nanocellulose with hydrophobic of NBR consequently limits the tearing propagation. The result was supported with the fracture surfaces morphology viewed under Fourier Emission Scanning Electron Microscopy (FESEM).

The nanocomposites of polypropylene (PP)/graphene were prepared by melt blending. The effects of the dosage of graphene on the flow and mechanical properties of the nanocomposites were investigated. The morphologies of fracture surfaces were characterized through scanning electron microscopy (SEM). The graphene simultaneous enhanced tensile and impact properties of nanocomposites. A 3.22% increase in tensile strength, 39.8% increase in elongation at break, and 26.7% increase in impact strength are achieved by addition of only 1 wt.% of graphene loading. The morphological behavior indicates the fracture surface of PP/graphene is more rough than that of pure PP.

The effects on the properties of recycled latex glove (RL-G) filled Epoxidized Natural Rubber (ENR 50) were studied. Both compounds were prepared by two roll mill at five different compositions of RL-G (5, 15, 25, 35 and 50 phr). The size range of RL-G particles i.e., S1 (300μm-700μm) and S2 (3cm-5cm) were used. The properties such as tensile properties (tensile strength, elongation at break, and stress at 100% elongation) and morphology studies were determined. The results indicated that the both size, S1 and S2 of recycled latex glove filled ENR 50 blends exhibited an increased in tensile strength and elongation at break for increasing weight ratio of RL-G. Scanning electron microscopy (SEM) of the fracture surfaces shows that the fine size, S1 RL-G/ENR50 exhibited high surface roughness and matrix tearing lines than the coarse size, S2 thus improving the compatibility of RL-G/ENR50 compounds. The results overall indicated that the fine size, S1of RL-G filled ENR50 contributed to the better properties such as tensile strength and surface morphology compared to the coarse size, S2 mainly at 15 phr of RL-G content.

This study aims was to determine the effect of palm oil fuel ash (POFA) composite as filler on the physical and mechanical properties of high impact polystyrene (HIPS) composites. The research methodology included preparation of raw materials, treatment POFA (hydration process of POFA), mixing using tumbler and then extruder, molding composite specimens, and testing. The variables used were weight ratio of HIPS with 140 mesh POFA at 95/5; 92.5/7.5; 90/10. The composites were tested by Fourier Transform Infrared (FTIR), ash content, specific gravity, tensile strength, elongation at break, impact strength, hardness test, and Scanning Electron Microscopy (SEM). The results of FTIR characterization shows the formation of –OH bonding that was suspected as Si-OH or Si-hydrat. Results of physical and mechanical properties of the composites shows that increase of the filler composition in HIPS-POFA composites until the ratio of 90/10, increase the specific gravity to 7.2% of the original, tensile strength did not change significantly to 28.4 MPa, elongation at break decreased to 2.7%, impact strength decreased to 3.183 KJ/m2, and the hardness increased to 110.5, and Scanning Electron Microscopy (SEM) test show the transformation of POFA structure on treated POFA and intercalation between the matrix and POFA.

Various electrospun epoxized natural rubber / poly (vinyl chloride) (ENR/PVC) blend nonwoven membranes were prepared by electrospinning technique. Various concentration of epoxidized natural rubber (ENR) solution in N,N-dimethylformamide (DMF) were directly added to PVC solution for plasticization of the electrospun nanofibrous. Differencial thermal analysis (DTA), thermogravimetry analysis (TGA), fourier transfrom infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM) were used to characterize the pristine and plasticized nanofibrous. DTA results indicated that the addition of ENR resulted in the shifting of glass transition temperature (Tg) towards lower temperatures. The blending of PVC with ENR is thermodynamically incompatible.
