The objective of this research was to observe the effect of MBTS/ZDEC ratio on dynamic properties, curing characteristic, morphology as well as hardness and resiliency of the NR/EPDM blends prepared by curatives migration control technique. The MBTS/ZDEC ratio were 1.6/0.0; 1.5/0.1; 1.4/0.2; 1.3/0.3 and 1.2/0.4 respectively on a fixed NR/EPDM ratio of 60/40. Compounds (EPDM and NR) were prepared separately using two roll mill. The blends with binary accelerator MBTS/ZDEC showed synergistic activity which provided higher crosslink density than those of single accelerator MBTS. Reduction of ts 2 and t 90 as well as cure rate index (CRI) indicated the more homogeneous crosslink density distribution within the rubber phase. Scanning electron micrograph showed that the blends with binary accelerator gave smoother surface. Binary accelerator resulted higher hardness. Increasing of ZDEC raised hardness followed by reduction of the resillience property.

“…The function f ( α ) is defined as follows for an autocatalytic curing reaction

f (α) = α^{m} {(1 - α)}^{n}, 0 \leq m \geq 1, n \geq 1

where m and n denote the reaction orders that depends on temperature.…”

The present paper investigates the influence of polyethylene (PE) and plasma modified polyethylene (PPE) as fillers in natural rubber (NR) compound. The NR/PE and NR/PPE compounds were prepared through mechanical mixing using two roll mill by varying their compositions. The morphology of the compounds was analyzed in detail using field emission scanning electron microscopy (FESEM) to understand the dispersion of PE and PPE in the NR matrix as well as its interfacial adhesion. Morphological analysis revealed that unmodified polyethylene was nicely dispersed in the NR matrix whereas plasma modified polyethylene showed agglomerated structure due to the polar functional groups on the PPE surface. The vulcanization kinetics and cure characteristics of natural rubber compounds containing PE and PPE were examined using an oscillating disc rheometer. The cure behavior of the composites were studied at different temperatures (140, 160, and 180 °C) using conventional sulphur vulcanization system. The addition of polyethylene influenced the cure properties to a great extent. Theoretical modeling was done to follow the mechanism of the cure reaction. The cure reaction was kinetically controlled at the beginning followed by the diffusion mechanism. The curing reaction was found to be autocatalytic and extent of reaction increased with increasing temperature.

“…Hal ini menunjukkan bahwa pada kompon NBR 26 dan NBR 28 menghasilkan jumlah ikatan silang yang lebih banyak dibanding kompon NBR 33. Torsi minimum (M L ) merupakan indikator viskositas kompon (Konar & Saha, 2012;Marković et al, 2013;Indra et al, 2013) serta memberikan informasi terkait kemampuan proses dari kompon (Nabil et al, 2013). Pada Tabel 2 terlihat bahwa nilai torsi minimum dari semua kompon NBR relatif sama, viskositas kompon NBR relatif sama disebabkan semua bahan baku NBR yang digunakan pada penelitian ini memiliki viskositas Mooney yang sama, yaitu 45 unit Mooney.…”

Natural and acrylonitrile-butadiene rubbers possess different vulcanization characteristics. Selection of the vulcanization system and temperature affects the mechanical properties of vulcanized natural rubber (NR) and acrylonitrile-butadiene rubber (NBR). In the present work, the effect of vulcanization temperature (150, 160, 170 ABSTRAKKaret alam dan karet akrilonitril-butadiena memiliki karakteristik vulkanisasi yang berbeda. Pemilihan sistem dan suhu vulkanisasi berpengaruh terhadap sifat mekanis vulkanisat karet alam (NR) dan karet akrilonitril-butadiena (NBR). Pada penelitian ini dipelajari pengaruh suhu vulkanisasi (150, 160, 170, dan 180 o C) terhadap sifat mekanis vulkanisat NR dan NBR. Pada NR dipelajari pengaruh sistem vulkanisasi yang berbeda (semi efisien, efisien dan donor sulfur), sedangkan pada NBR lebih difokuskan terhadap pengaruh kandungan akrilonitril yang berbeda (26, 28, dan 33% b/b). Karakteristik pematangan dan sifat mekanis karet NBR menunjukkan bahwa karet NBR dengan kandungan akrilonitril yang rendah lebih sesuai divulkanisasi pada suhu rendah (150 o C), sedangkan karet NBR dengan kandungan akrilonitril yang tinggi lebih sesuai divulkanisasi pada suhu tinggi (170 o C). Vulkanisat karet alam lebih sesuai divulkanisasi menggunakan sistem vulkanisasi semi efisien dengan suhu vulkanisasi sebesar 150 o C.Kata kunci: suhu vulkanisasi, akrilonitril, NBR, karet alam, sifat mekanis.
