“…The EPDM compounds with silica are very appropriate for applications where light colors are required. There are some recent investigations concerning EPDM compounds with silica, especially focused on the matrix-filler interaction with the use of compatibilizing agents [5][6]. In this paper, the authors wanted to study the effect of adding 20 phr of different particle size precipitated silica, produced in Venezuela, to EPDM compounds, with the purpose of improving their mechanical properties without increasing the costs, so they can be competitive with their equivalent formulations with carbon black.…”

In this work we present the influence of different particle size (surface areas: 120,150, 200 and 250 m2/g) and size distribution of precipitated silica on the mechanical properties of Ethylene- Propylene-Diene (EPDM) rubber. The vulcanization system employed was efficient. Compounds were prepared using a Banbury internal mixer. Tensile and tear properties of vulcanized blends were determined according to ASTM D412 and ASTM D624 procedures, respectively. Results show an increasing tendency on tensile properties when particle size decreases, due to the better dispersion of the filler and to a greater interaction with the rubber. Increases of up to 500% on tensile strength and 400% on tear strength were observed. However, there was an incoherent behavior for the silica with surface area of 200 m2/g (Si-200), so size distribution of the aggregates was experimentally determined by a microphotography study. Secondary aggregates size distribution was very different for each type of silica. Aggregates for Si-200 presented a bimodal distribution where the greater frequencies correspond to aggregates with surface area higher than the corresponding values for the Si-120. This fact could explain why the mechanical properties of the EPDM filled with Si-200 are not in between the values of the compounds filled with Si-150 and Si-250.

“…In recent years, silica has been introduced as a reinforcing filler for rubbers from economic factors and its ability to offer major functional benefits, such as low thermal expansion, chemical resistance, hard surface, high dielectric strength, etc., [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. In fact, many studies have shown that the technical properties of silica reinforced compounds are better than those of carbon black filled ones [31][32][33][34][35][36][37].…”

The silane (TESPD) treated silica-filled silicone rubber (SR)/natural rubber (NR) blends are studied with regard to their mechanical, thermal, and optical properties. Two grades of SR, with and without vinyl group are used and the results are compared. The effects of a vinyl functional group in SR with respect to vibration isolation property, and mechanical properties are investigated to find maximum torque, tensile strength, tensile modulus, elongation at break, hardness and tan δ. The compounds are cured with sulfur, peroxide and peroxide/sulfur combination. The results show that the presence of the vinyl group in SR helps improve the mechanical and thermal properties of the SR/NR blend. Scanning electron microscopy (SEM) photographs show that the silica particles are well dispersed in the rubber matrix. Thermal properties including thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and heat resistance are also studied. It shows the presence of the vinyl group in the SR/NR blend curing with the peroxide/sulfur combination improves both mechanical properties and the vibration properties.

“…The specified materials affect not only the final product properties but also the behavior of the components. Many researchers attempted to develop alternative methods to improve the formulation of the EPDM dough mixture and improve the properties of the final product [10][11][12][13]. In this study, different compositions of EPDM rubber were prepared using carbon black, precipitated silica, silane, antiozonants, homogenizer, and peroxide crosslinking agent, and mixing was carried out in two different Banbury rotors (tangential and intermeshing types).…”

Rubbers have a wide range of usage in polymeric materials since materials with a wide variety of mechanical properties can be obtained by varying the type or addition rates of the materials contained in the rubber in addition to the important properties such as high elasticity, good abrasion resistance, and low deformation. Highperformance properties of the material are provided by cross-linking (vulcanization). Raw rubbers do not contain cross-links. In this study, it was aimed to examine the changes that may occur in the mechanical properties of the newly prepared EPDM rubber by changing the composition of the available Ethylene Propylene Diene Monomer (EPDM) rubber. For this purpose, a new rubber mixture, of which composition had been previously known and which was developed in this study, was prepared in two different Banbury mixers (tangential and intermeshing types), and both samples were subjected to mechanical and rheological analyses. The most important criteria in mechanical properties are tensile strength and elongation at break. As these properties increase, the final product becomes more durable. When tensile strength and elongation at break of the EPDM rubber prepared according to the new formulation were compared with the available EPDM rubber, a significant increase was observed in these two values in the EPDM rubber sample prepared with the new formula. In conclusion, it was shown with the characterization analyses that the newly developed modified EPDM rubber can be used in the rubber industry.
