“…Hal ini disebabkan semakin meruahnya struktur ENR-46 terbentuk setelah reaksi epoksidasi sehingga karet epoksi lebih kaku (Handayani, 2011). Tensile Strength merupakan hasil pengujian mekanik secara statis dengan cara sampel ditarik dengan pembebanan pada kedua ujungnya dengan gaya tarik sebesar P (Yuniari, 2015). Tensile Strength sangat berkaitan dengan ikatan silang (crosslinking) pada kompon karet.…”

Penelitian ini untuk mengetahui pengaruh penambahan Natural Rubber (NR) dan Epoxidation Natural Rubber (ENR-46) dengan kompatibiliser Chlorprene Rubber (CR) pada aplikasi kompon termoplastik Poly Vinyl Chloride (PVC) dan Nitrile Butadiene Rubber (NBR), variabel penelitian meliputi ENR-46/PVC/NBR/CR, NR/PVC/NBR/CR dan CR-NR/PVC/NBR, CR-ENR-46/PVC/NBR. Parameter pengujian sifat fisik-mekanik : Hardness (Shore A), Tensile Strength (Mpa), Elongation at Break (%) dan ketahanan terhadap pelarut minyak (n-Pentane, Toluene, Hexane dan Pertalite). Hasil penelitian didapatkan untuk sifat fisik-mekanik, semakin banyak penambahan NR Kekerasan kompon termoplastik akan menurun, Tensile Strength dan Elongation at Break kompon akan meningkat begitu juga dengan CR-NR. Tetapi berbanding terbalik hasilnya untuk ENR-46 dan CR-ENR-46. Pengujian Ketahanan terhadap pelarut minyak semakin banyak penambahan ENR-46 Ketahanan kompon termoplastik terhadap pelarut akan meningkat, hasil yang sama juga pada CR-ENR-46. Tetapi berbanding terbalik hasilnya dengan penambahan NR dan CR-NR pada kompon termoplastik.

“…Elongation at Break merupakan ukuran suatu bahan yang diartikan sebagai ketahanan material tersebut terhadap deformasi elastis. Semakin besar modulusnya maka semakin kecil regangan elastis yang dihasilkan akibat pemberian tegangan (Yuniari, 2015). Pada dasarnya nilai Elongation at Break berbanding lurus dengan tensile strength.…”

“…Hardness affects the appearance and durability of rubber products, and its value is related to the amount of filler added [4]. The more reclaimed rubber is added will provide a higher value of hardness [10].…”

“…Rubber are important elastomer [1], but since vulcanized rubbers having crosslinked structure and contain many additive its cannot degradated easily [2] [3]. The solid waste potentially damaged the environment if dumped without proper treatment [4]. Many attempt has been made to solved the problems, such as landfill, electrical generator and pirolysis [2][5] [6].…”

Rubber solid waste amount increased continuosly and caused environmental problem since it is very difficult to be naturally degraded. Therefore, the interest of using rubber waste as raw material for new rubber product is increased. Reclaimed rubber can be used as filler aditif for rubber processing. The aim of this research was to study the effect of UV aging on the rubber product as the reclaimed filler added. The mixing of the rubber and the additives used the kneader and open mill. The vulcanization process was done by hydraulic press. In this research, the reclaimed rubber addition was varied as follows: 12,5; 37,5 and 62,5 phr. The products quality differences before and after the UV aging evaluated using physical tests. The result of FTIR showed that the polymer chain were broken by ultraviolet radiation. The physical test gives result that the hardness and tensile strength decreased, but the elongation is increased after UV aging.

“…A conventional sulphur vulcanization system was employed with the following formulation: RSS 55 phr, butyl 45 phr, carbon black 50 phr, NPCC 5 phr, TMQ 2 phr, 6PPD 1 phr, wax 0.5 phr, ZnO 5 phr, aflux 42 1 phr, paraffinic oil 8 phr, TMT 0.5 phr, MBT 0.5 phr, and sulphur 2.5 phr. Blending of NR/IIR and additives was done according to previous study using a laboratory two-roll mill (Yuniari et al, 2015). Cure time of the blended compound was determined by a moving die rheometer (MDR) Gotech 3000A.…”

The knowledge of how rubber breakdown on heating in oxidative environment is important in processing and using the material. In this work, thermogravimetric analysis were carried out and three iso-conversional kinetic models were utilized to get apparent activation energies of thermal degradation of natural rubber (NR)/butyl rubber (IIR). Blending of NR/IIR and additives was conducted using a laboratory two-roll mill. Thermal degradation of the blends and its kinetic parameters were analysed using thermo gravimetric analysis (TGA) with heating rates of 5, 10, 15, and 20°C/min. The kinetic parameters were determined by three isoconversional models (Kissinger, Doyle, and Flynn-Wall-Ozawa (FWO) model). The result revealed that the thermal decomposition of the blend occurs in two stages and the derivative thermogravimetric (DTG) peaks tends to shift to a higher temperature during TGA measurement. The values of DTG peaks increases with an increase of the heating rate, and the three iso-conversional models gave similar apparent activation energies. The activation energy obtained can be used to predict thermal lifetime of the material.
