“…The reinforcement effect ratio increases up to 6 phr HNTs, then slightly declines, indicating higher reinforcing e ciency in the PVMQ matrix at this loading. However, beyond 6 phr HNTs, the ratio slightly decreases due to nanotube aggregation within the elastomer matrix [47].…”

Halloysite nanotubes (HNTs), an innovative material, were integrated into a silicone rubber (SR) matrix. This investigation aimed to assess the influence of varying HNTs concentrations on the curing behavior, mechanical properties, swelling resistance, and microstructural features of SR/HNTs nanocomposites. These nanocomposites were formulated by incorporating HNTs at different concentrations (0-10 phr) through a two-roll mill. The cure characteristics revealed an upsurge in maximum torque (MH) with escalating HNTs loading, accompanied by a decrease in cure time (t90) and scorch time (ts2). The abrasion resistance exhibited an increment with increasing HNTs loading, reaching optimal levels at 6 phr, and tensile characteristics demonstrated improvement up to this optimal loading. Morphological analysis illustrated the uniform dispersion of HNTs within the SR matrix, indicating a positive interaction between HNTs and silicone rubber.

“…This method's weakness is its inability to accurately determine the vulcanizing agent's content. (2) Thermal analysis methods, where the DSC technology is founded on the idea that reaction heat is only produced by crosslinking processes and is directly correlated with the strength of those reactions. But there is no support for this notion for complex reaction systems [58].…”

“…It is possible to obtain materials with extra properties while retaining the majority of their original characteristics by blending more than one kind of elastomers [1][2]. In fact, it is simple to alter the blends to match the performance and cost requirements of the current markets.…”

In this study, the impacts of nanosilica on the properties of natural rubber and ethylenepropylene-diene rubber blends (NR/EPDM; 70/30 phr/phr) were examined. Utilising the melt compounding method, the composites were developed. The effects of thioctic acid (TA) on the surface modification of silica (SiO2) are compared to those of bis(3triethoxysilylpropyl)tetrasulfide (TESPT)/polyoxyethylene (20) sorbitan monolaurate (TWEEN-20) on the curing, mechanical, tensile and compression set, and swelling properties of nanocomposites in this study. In NR/EPDM composites, the nanosilica made from rice husk ash was employed as reinforcing nanofiller. For the production of rubber composites, the interaction at the interface between the nanosilica and the NR/EPDM matrix is essential. The 2:1 ratio between TESPT and TWEEN-20 is maintained in this study's utilisation of TESPT and TWEEN-20 as a silica modifier. It has been found that the attributes of NR/EPDM blends are mostly influenced by the presence of TA modified nanosilica. When compared to pure NR/EPDM blends, the incorporation of TA modified nanosilica considerably increased tensile and tear strength by up to 76% and 48%, respectively. Swell measurement, abrasion resistance, and FESEM all provided additional evidence in support of these conclusions.

The in uences of nanosilica and modi ed nanosilica on cure, compression set, mechanical and swelling characteristics are studied in blends of ethylenepropylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the nanosilica made from rice husk ash (RHA) was utilised as a reinforcing nano ller. The interaction between the nanosilica and the EPDM/SBR matrix at the interface is crucial for the production of rubber composites. This study uses bis [3-(triethoxysilyl)propyl] tetrasul de (TESPT) and polyoxyethylene (20) sorbitan monolaurate (TWEEN-20) as a silica modi er, with the ratio of TESPT to TWEEN-20 maintained at 2:1. The cure and mechanical characteristics, compression set, abrasion and swelling resistance increased with the incorporation of nanosilica and modi ed nanosilica. By interacting at the interface between silica nanoparticles and the EPDM/SBR rubber matrix, TESPT with the TWEEN-20 modi er exhibits a considerable effect on cure characteristics, mechanical qualities, and swelling resistance.
