“…When working in a nuclear plant building using instrument installed with rubber, etc., degradation of the rubber is serious problem. In general, ordinary rubber becomes hard after γ-irradiation so that the degradation can be ascertain In general, as indicated in other studies on ordinary rubber without a filler that is vulcanized using sulfur such as SBR [22], in blends of polybutadiene rubber and NR [24], and hydrogenated NBR [25], more C-C crosslinks are created than C-S crosslinks by γ-irradiation. As such, the rubber hardens.…”

We have performed sequential studies on new types of soft rubber for their application as artificial skin in robots and haptic sensors. Based on a proposed electrolytic polymerization method and novel adhesion technique for rubber and a metal that utilizes a metal complex hydrate, we have developed an MCF rubber sensor. This sensor uses a magnetic compound fluid (MCF), natural rubber (NR-latex) or chloroprene rubber latex (CR-latex), and requires the application of a magnetic field. The potential application of the developed sensor in various engineering scenarios and our daily lives is significant. In this regard, we investigated the effects of γ-irradiation, infrared radiation, microwaves, and a thermal source on the MCF rubber sensor. We established that the MCF rubber is effective enough to be used for power generation of broadband electromagnetic waves from γ-rays to microwaves, including the range of the solar spectrum, which is the typical characteristic obtained in the present investigation. The remarkable attribute is that the MCF rubber sensor dose is not degraded by γ-irradiation. We also demonstrated the effectiveness of the MCF rubber sensor in energy harvesting.

“…Warm-mix asphalt (WMA) technology has grown in popularity in recent years because it can drastically lower the working temperature of the bitumen mixture while ensuring its performance and minimising pollutant gas emissions during the mixing and paving stages, resulting in improved on-site construction conditions [61][62][63]. Other advantages of WMA technology include lesser fuel consumption, a faster construction period and transportation time opening and less bitumen thermal ageing [30].…”

Conventional bitumen pavement is no longer suitable for handling increasing loads and weather variations, which cause road deterioration, Thus, the modification of bitumen has been suggested to counter this issue. This study provides a detailed assessment of various additives for modifying natural rubber-modified bitumen used in road construction. This work will focus on the use of additives with cup lump natural rubber (CLNR), which has recently started to gain attention among researchers, especially in rubber-producing countries such as Malaysia, Thailand and Indonesia. Furthermore, this paper aims to briefly review how the addition of additives or modifiers helps elevate the performance of bitumen by highlighting the significant properties of modified bitumen after the addition of modifiers. Moreover, the amount and method of application of each additive are discussed further to obtain the optimum value for future implementation. On the basis of past studies, this paper will review the utilisation of several types of additives, including polyphosphoric acid, Evotherm, mangosteen powder, trimethyl-quinoline and sulphur, and the application of xylene and toluene to ensure the homogeneity of the rubberised bitumen. Numerous studies were conducted to verify the performance of various types and compositions of additives, particularly in terms of physical and rheological properties. In general, additives enhance the properties of conventional bitumen. Future research should investigate CLNR because studies on its utilisation are limited.

“…Elastomer blends have attracted a lot of interest from researchers all over the world in the recent decade. [1][2][3][4][5][6] Even though there are numerous types of elastomers, natural rubber has received the most attention over the years. 7,8 Natural rubber offers numerous advantages over synthetic rubber in general, such as good processability, high tensile strength, cost-effectiveness, and excellent tear and abrasion resistance.…”

The most important goal of this work was to investigate the different physical and mechanical properties of the nanoclay (montmorillonite, MMT)-filled 50/50 wt.% of natural rubber/styrene butadiene rubber (NR/SBR) blend containing 40 phr of waste tire rubber (WTR) in the presence of bio-resin. The MMT was added into the NR/SBR/WTR blends and processed via a two-roll mill to prepare blends at 0, 5, 10, 15, and 20 phr of nanoclay filler and a constant concentration of 10 phr of bio-resin. The morphology, rheological, percent of swelling weight, and mechanical properties of the MMT-reinforced NR/SBR/WTR blends were examined. The cure characteristics of the blends showed that MMT significantly affected the scorch and vulcanization times, torques, and curing rate of NR/SBR/WTR blends at all filler contents. Also, the findings revealed that the MMT was an efficient reinforcing material for the NR/SBR/WTR blend, improving crosslink density, tensile and tear strengths, hardness, compression set, and abrasion resistance. The tensile strength of filled NR/SBR/WTR blends achieved its maximum value (11.2 MPa) when the MMT content was 15 phr. While the elongation percent of the filled blends decreased for all MMT concentrations compared with the pristine blend. The elastic modulus and tear strength of the blends improved as the MMT loading increased. The hardness (Shore A) continued to increase with increasing MMT loading. On the contrary, the rebound resilience gradually decreased leading to improved interaction between the matrix and filler.
