“…sults in two types of end chain reaction with the carbon black surface and nonpolar chain terminal interacted with the rubber molecule. According to Gujel et al the interaction between the filler and elastomer is increased by the addition of vegetable oil (Gujel et al, 2014), or in this case, the addition of castor oil.…”

“…MACO also contains long chain unsaturated fatty acid ester which results in two types of end chain reaction with the carbon black surface and nonpolar chain terminal interacted with the rubber molecule. According to Gujel et al, vegetable oil, or in this case is castor oil, will improve the interaction between filler and rubber matrix (Gujel et al, 2014).…”

Recently, much attention has been focused on research to replace petroleum-based plasticizers, with biodegradable materials, such as biopolymer which offers competitive mechanical properties. In this study, castor oil was modified with maleic anhydride (MAH) to produce bioplasticizer named maleated anhydride castor oil (MACO), and used in nitrile butadiene rubber (NBR)/poly vinyl chloride (PVC) blend. The effect of MACO on its cure characteristics and mechanical properties of NBR/PVC blend has been determined. The reactions were carried out at different castor oil (CO)/xylene ratios, i.e. 1:0 and 1:1 by weight, and fixed CO/MAH ratio, 1:3 by mole. DOP, CO, and MACO were added into each NBR/PVC blend according to the formula. It was found that the viscosity and safe process level of NBR/PVC blend is similar from all plasticizer, however, MACO (1:0) showed the highest cure rate index (CRI). MACO-based plasticizer gave a higher value of the mechanical properties of the NBR/PVC blend as compared to DOP based plasticizer. MACO (1:1) based plasticizer showed a rather significance performance compared to another type of plasticizers both before and after aging. The value of hardness, elongation at break, tensile strength, and tear strength were 96 Shore A, 155.91 %, 19.15 MPa, and 74.47 MPa, respectively. From this result, NBR/PVC blends based on MACO plasticizer can potentially replace the DOP, and therefore, making the rubber blends eco-friendly.

“…The modulus at 300% is defined as the tensile stress necessary to elongate a specimen to 300% of its original length. Although other elongations may be used (as 50% and 100%), 300% is the one most often employed for rubber and flexible polymers (Gujel et al, 2014). In general, the evaluated mechanical properties of the silicon samples remain unaffected after the swelling test because these samples have small swelling indices.…”

An engine industry from Caxias do Sul city (RS, Brazil) has developed tests with biofuels to adapt their products to new fuel trends. Thus, this study aims to examine the components of their engines with potential degradation in the biodiesel usage. The most important aspects that were studied include fuel hoses, sealing rings and painting degradation. This work evaluated polymeric materials in terms of the direct contact with biodiesel from soybean in different proposed compositions with diesel fuel and compared the currently used materials with other elastomers that were proposed by the manufacturers of these components to choose the best performance for this application. The paint performance was also verified to evaluate the resistance aspects to fuels and to compare them to the proposed improvements to these engines. The results indicate that it is possible to use the proposed fuel hoses and sealing rings for some applications in specific biodiesel ratios. Additionally, the blistering and adhesion tests appear to be satisfactory for some of the studied systems.

“…Faktor lain yang mempengaruhi ketahanan sobek adalah kerapatan ikatan silang dalam vulkanisat karet. Seperti diketahui bahwa nilai ketahanan sobek meningkat seiring dengan sedikit peningkatan kerapatan ikatan silang, hingga mencapai puncaknya, saat jumlah optimumnya tercapai (Gujel et al, 2014).…”

The objectives of this research were to study the manufacturing method, to obtain the best formula and to study the morphological properties of shoe sole from natural rubber latex. ABSTRAKTujuan dari penelitian ini adalah untuk mempelajari metode pembuatan sol sepatu dari lateks karet alam dengan cetak tuang, mendapatkan formula terbaik berdasarkan sifat mekanik, serta mempelajari sifat morfologinya. Metode tersebut dilakukan dengan tiga tahap, yaitu pembentukan, perendaman dalam air, dan vulkanisaasi. Sol sepatu lateks dibuat dengan bahan pengisi Nano Precipitated Calcium Carbonate (NPCC) sebanyak 5 phr, dan bahan pengisi tambahan CaCO 3 bervariasi mulai dari 0, 5, 10, 15, dan 20 phr. Pengujian menggunakan metode dan syarat mutu sesuai SNI 0778:2009. Hasil penelitian menunjukkan bahwa formula terbaik yang didapat menggunakan kombinasi bahan pengisi NPCC/CaCO 3 sebesar 5/5 phr. Sifat mekanik yang diperoleh adalah tegangan putus sebesar 169,87 kg/cm 2 , perpanjangan putus sebesar 648,03%, kekerasan sebesar 46,33 shore A, ketahanan retak lentur yang baik dan tidak retak, densitas sebesar 0,93 g/cm 3 , ketahanan kikis 346,26 mm 3 , dan perpanjangan tetap 50% sebesar 2,15%. Seluruh parameter uji memenuhi syarat mutu SNI 0778:2009, kecuali kekerasannya.Kata kunci: lateks karet alam, sol sepatu, cetak tuang.
