“…Figure shows that the stabilization torque values, which are taken 10 min into the mixing process, indicate that blending sequences and MLF loadings influenced the stabilization torque values. The stabilization torque reached at the completion of melt mixing can be related to the viscosity of the final blend, used to predict the processibility of the blends . It clearly indicates that the B1 system exhibits a lower stabilization torque compared with other systems in all the blends compositions.…”

Ethylene vinyl acetate [EVA])/(natural rubber [NR])/ (Mengkuang leaf fiber) (MLF) thermoplastic elastomer composites were prepared by using three different blending sequences in an internal mixer. The blending sequences studied were (i) B1: NR was added followed by MLF into the molten EVA; (ii) B2: MLF was added followed by NR into the molten EVA; (iii) B3: MLF was added followed by EVA into the molten NR. The effect of different blending sequences and fiber loadings from 10 to 40 parts by weight per hundred parts of resin on the torque development, tensile properties, thermal degradation, and morphology of EVA/NR/MLF composites was studied. Of the blending sequences investigated, the B1 system is considered the best method for the preparation of EVA/NR/MLF composites. The B1 system produces composites with lower stabilization torque, higher tensile strength, and better thermal stability compared with other systems. At 40 parts by weight per hundred parts of resin of MLF loading, the tensile strength of the composite prepared by using the B1 system was 15% higher than that of B2 system composites, and 8% higher than that of the B3 system. Scanning electron micrographs of the tensile fracture surfaces indicated this system also had good fiber dispersion in the EVA/NR matrix. An increase in MLF loading resulted in an increase of the values of the stabilization torque and the Young's modulus, but a decrease in values of the tensile strength, the elongation at break, and the thermal stability of the composites. Scanning electron microscopy revealed increased fiber pullout in the composites as the loading increased.

“…The processing torque–time curve has been utilized as qualitative information regarding the processing characteristics, the rheological behavior, and the viscosity of the composites during the mixing process. The value of stabilization torque that reached at the end of the completion of mixing can be used to predict the viscosity of the final composites . Figure shows the relationship between the stabilization torque and the MLF loading of untreated and treated EVA/NR/MLF composites.…”

In this article, the effect of alkaline peroxide bleaching treatment using hydrogen peroxide on mengkuang leaf fiber (MLF) to the tensile, thermal properties and water absorption of thermoplastic elastomer composites based on ethylene-vinyl acetate/natural rubber and MLF was investigated. Fiber morphology and the fiber-matrix interface were further characterized by scanning electron microscopy (SEM). Treated composites showed better tensile properties than untreated fiber composites. SEM of the fractured surfaces of the composite specimens indicates that the bleaching treatment improved the interfacial interaction between the fiber and the matrix. The results of thermogravimetric analysis showed a higher thermal stability for treated composites than untreated composites. Furthermore, alkaline bleaching treatment has resulted in reduction of water absorption from 31% to 26% as compared with untreated composites. J. VINYL ADDIT. TECHNOL., 26:127-134, 2020. FIG. 6. Scanning electron micrographs of MLF subjected to different treatments. (a) untreated MLF (mag 500×), (b) untreated MLF (mag 700×), (c) treated MLF (mag 500×), and (d) treated MLF (mag 700×).

“…KAE 26% mol memiliki parameter kelarutan sebesar 17,4 MPa 1/2 dan KAE 48% mol memiliki parameter kelarutan sebesar 18,2 MPa 1/2 (Gelling, 1991 (Kongsin & Lewan, 1998;Thomas et al, 2012). Penggunaan KAE sebagai kompatibiliser juga telah dilakukan pada campuran KA/ NBR (Onyeagoro, 2012) dan KA/etilena vinil asetat (EVA) (Yong et al, 2007), komposit NBRnanoclay (Rajasekar et al, 2009) dan nanokomposit KA-organoclay (Teh et al, 2004). Beberapa penelitian terdahulu menunjukkan bahwa penambahan kompatibiliser dapat meningkatkan sifat mekanis dan ketahanan minyak campuran KA/ NBR serta mempercepat waktu pemasakan vulkanisat (Thomas et al, 2012) dan komposit (Rajasekar et al, 2009), namun belum ada informasi mengenai ketahanan campuran tersebut di dalam n-pentana.…”

The improvement of the compatibility of natural rubber (NR)/acrilonitrile-butadiene rubber (NBR) blend on rubber seal vulcanizate has been done by the addition of chloroprene rubber (CR) or epoxidized natural rubber (ENR) as compatibilizer. Rubber seal compound was made of NR and NBR blend (BN) with CR (BCR), and ENR with epoxy content of 10% (BENR10), 20% (BENR20), 30% (BENR30), 40% (BENR40), and 50% (BENR50 ABSTRAKPeningkatan kompatibilitas pencampuran karet alam (KA) dan akrilonitril-butadiena (NBR) pada vulkanisat karet perapat dilakukan dengan menambahkan kompatibiliser karet kloroprena (CR) atau karet alam epoksidasi (KAE). Kompon karet perapat dibuat dari campuran KA dan NBR (BN) dengan kompatibiliser CR (BCR) dan KAE dengan kandungan epoksi 10% (BKAE10), 20% (BKAE20), 30% (BKAE30), 40% (BKAE40), dan 50% (BKAE50). Komposisi pada masing-masing formula diseragamkan dengan perbandingan KA:NBR sebesar 40:60 dan KA:kompatibiliser:NBR sebesar 40:5:55. Kompon divulkanisasi dengan sistem efisien pada suhu 150 0 C. Penambahan kompatibiliser CR memperbaiki karakteristik pematangan, pampatan tetap, dan ketahanan n-pentana vulkanisat KA/NBR (BN). Sedangkan penambahan kompatibiliser KAE memperbaiki sifat elastis vulkanisat. Keelastisan dan ketahanan n-pentana BKAE meningkat seiiring kandungan epoksi KAE.Kata kunci: karet perapat, kompatibiliser, ketahanan n-pentana, sifat mekanis. PENDAHULUANKaret perapat (rubber seal) pada tabung gas liquified petroleum gas (LPG) dipasang untuk mencegah terjadinya kebocoran gas pada waktu pengisian atau penggunaan tabung LPG serta memperkuat kedudukan regulator. Pada pembuatan produk karet perapat, bahan baku karet yang digunakan harus tahan terhadap gas LPG. Pada SNI karet perapat (SNI 7655:2010), ketahanan karet terhadap gas LPG didekati melalui pengujian ketahanan karet terhadap pelarut non polar n-pentana. Salah satu alternatif bahan baku pembuatan karet perapat adalah karet akrilonitril butadiena (NBR). NBR memiliki ketahanan yang baik terhadap oli
