“…Rubber is a type of vital material that is frequently used in aerospace, automotive, marine and medicinal applications because of its many distinct characteristics. Generally speaking, in order for rubber to achieve the application requirements for outstanding mechanical properties, it must be chemically cross-linked and strengthened with llers [12][13]. For this investigation, EPDM and NBR were chosen due to their unique physical characteristics and incompatibility.…”

The main inorganic component of rice husk is silica. Washing the rice husk, followed by combustion and chemical treatment, produced high-surface area amorphous extracted nanosilica (NS) and modified extracted nanosilica (mNS). It was established to reinforce a blend of ethylene-propylene-diene monomer (EPDM) and acrylonitrile-butadiene rubber (NBR) using different amounts of mNS, specifically 2, 4, 6, 8, and 10 phr. The cure properties, mechanical, physical, and swelling resistance examinations of the sulphur-cured nanocomposites were studied. The results showed that while the torques were prolonged with increasing mNS concentration, the optimum cure time (t90) and scorch time (ts2) decreased. The homogeneous distribution of nanosilica particles throughout the rubber matrices was confirmed by the FESEM micrographs. The outcomes guaranteed a discernible improvement in the nanocomposites' examined qualities.

“…However, asbestos is carcinogenic and has serious environmental problems [ 14 ]. The improved mechanical, and morphological properties of EPDM blends with some other fillers including nano clay [ 15 ], silicon carbide (SiC), carbon fiber (CF) [ 16 ], and nano-silica [ 17 ] have also been reported in different studies. In present research we tried to develop low-cost, low-density EPDM-based materials by using carbon fiber fabric, asbestos and vulkasil-C fillers and studied these materials for improved thermal insulation performance.…”

The most widely used filler in EPDM-based thermal insulation materials is asbestos which is hazardous to health and environment. The main motivation of this study was to develop improved EPDM-based materials by partially or completely replacing asbestos with other fillers. EPDM-Esprene501A and EPDM-Keltan®4869DE were used and the effect of three fillers (vulkasil-C, asbestos, carbon fiber fabric) on mechanical, ablative, physical, thermal, and electrical performances have been investigated. Samples were divided into phase-1, -2, and -3 by compounding EPDM with various percentages of fillers and other necessary ingredients. It was observed that asbestos and carbon fiber in the absence of vulkasil-C did not import enough reinforcement to EPDM-matrix. Experimental evidence showed that presence of vulkasil-C has not only enhanced mechanical properties but also improved thermal and ablation performance of EPDM-based composites. The swelling index was found comparatively lower with vulkasil-C than that with other fillers. Among two EPDMs, EPDM-Esprene based composites have shown comparatively better performance. Among all (phase-1–3) samples, E100K0VA (phase-2) has shown greater mechanical (stress 3.89 MPa; strain 774%), ablative (linear 0.1 mm/s; mass 0.05 g/s), and thermal (material left 91.0%) properties. Overall findings indicated improved properties of EPDM in the presence of vulkasil-C and may help to develop better heat resistant materials.

“…Compared to conventional filler, the high interfacial surface area of nanofillers lessen the quantity of filler required and thus reduces the specific gravity of the compound and heat generation that ultimately lead to the high performance of tyre and its better fuel efficiency. [10][11][12][13] Silica is one of the promising environment friendly and inexpensive reinforcing filler, which can be prepared from renewable resources. Among different inorganic fillers, nanosilica stands out as it provides significant improvement in thermal, mechanical and dynamic properties of elastomers.…”

The effect of factors on the process of chemical modification of tar with formaldehyde using a sulfuric acid as the catalyst has been studied. By using experimental results, the adequate statistical-mathematical (ESM) model has been developed. Based on this model, the optimal values on the process of chemical modification of tar with formaldehyde using a sulfuric acid as the catalyst have been identified, bringing about optimal penetration value and softening point of the modified tars. Data predicted on the basis of the ESM model were compared with empirical evidence about modified tars preparation.
