This paper describes the utilisation of urea as a single chemical agent to
obtain deproteinised high ammoniated natural rubber latex (HA-NRL). The role of
urea in HA-NRL deproteinisation was further investigated by employing two
different concentrations of urea solution which are low (0.01–0.05%) and high
(1.0–5.0%) concentrations. The study assessed the potential usage of urea as a
single denatur... hiện toàn bộ
Physiological Responses of Two Rubber Tree Clones with Differential Cold-Tolerant Potential to Cold StressSpringer Science and Business Media LLC - Tập 20 - Trang 117-129 - 2017
J. X. Wang, Y. Li, W. M. Tian
Improvement of cold tolerance in rubber tree is essential for sustainable
increase of natural rubber production when the planting region has been
extending outside of the traditional areas. In the present study, physiological
responses to cold stress were determined in two rubber tree clones with
differential cold tolerance. Upon cold stress, the level of endogenous hydrogen
peroxide was significa... hiện toàn bộ
Combined effects of styrene–butadiene rubber (SBR) latex and recycled aggregates on compressive strength of concreteSpringer Science and Business Media LLC - Tập 24 - Trang 107-120 - 2021
Usman Ali, Saman Shahid, Shahid Ali
Recycled Aggregates (RA) produced from the construction and demolition (C&D)
waste can be utilized along with Natural Aggregates (NA) to optimize the
concrete’s compressive strength (CS). We evaluated the combined effects of
Recycled Aggregates Concrete (RAC) and Styrene–Butadiene Rubber (SBR) Latex on
the concrete’s workability and compressive strengths. 72 concrete specimens of 4
groups with res... hiện toàn bộ
Modeling tensile modulus of nanoclay-filled ethylene–propylene–diene monomer/styrene–butadiene rubber using composite theoriesSpringer Science and Business Media LLC - Tập 24 - Trang 847-856 - 2022
M. S. Ravi Theja, Naveen Kilari, S. Vishvanathperumal, V. Navaneethakrishnan
Nanocomposites of ethylene–propylene–diene monomer (EPDM)/styrene–butadiene
rubber (SBR) (80/20) filled with different content of nanoclay 0–10 phr (parts
per hundred rubber) were prepared on the two-roll mill. Tensile modulus was
studied using composite theories. Transmission electron microscopy showed the
existence of intercalated, aggregated, and partially exfoliated structures. The
tensile mod... hiện toàn bộ
Numerical studies on the heat dissipation process in elastomers under rotating loading directionSpringer Science and Business Media LLC - - 2021
Mohamed A. Abdelmoniem, Bülent Yagimli
AbstractElastomeric components such as car bearings and vibration dampers are
subjected to dynamic loads with various amplitudes and loading directions during
operation. To better understand the lifetime expectancy of these components it
is required to implement a material model that sufficiently accounts for the
material thermo-mechanical behaviour. This paper implements a finite
viscoelastic mod... hiện toàn bộ
Mechanical and physical characterizations of styrene butadiene rubber: bagasse compositesSpringer Science and Business Media LLC - Tập 23 - Trang 23-31 - 2019
Eyad Sayed Abdallah Khalaf, H. Farag, E. M. Abdel-Bary
The incorporation of prevalent industrial wastes (i.e. residues) from sugar
industries as reinforcing fillers in rubber composites has emerged as a viable
solution, enabling improvements in the environment, and getting rid of bagasse
waste has also resulted in cost reduction of the final rubber products. In this
study, the use of maleic anhydride was proposed to improve the interfacial
adhesion be... hiện toàn bộ
An experimental study using 3-aminoproplymethyldiethoxysilane (APMDS) to improve biocompatibility of NR latex filmSpringer Science and Business Media LLC - Tập 26 - Trang 125-137 - 2023

To improve the biocompatibility of dipped films from natural rubber latex (NRL)
without compromising physical strength, high ammoniated NRL (HA-NRL) compounding
formulations were devised by manipulating the amount of compounding ingredients
and additive materials. In this study, the compatibility of
3-aminoproplymethyldiethoxysilane (APMDS) with calcium carbonate (CaCO3) filler
in zinc diethyldith... hiện toàn bộ
Evaluation of fuller's earth clay ceramic membrane in treating raw rubber-processing wastewaterSpringer Science and Business Media LLC - Tập 26 - Trang 205-219 - 2023
S. Lakshmi Sandhya Rani, K. V. V. Satyannarayana, R. Vinoth Kumar
Ceramic membranes are considered more effective for wastewater treatment
applications than polymeric membranes because of their excellent resistance to
thermal and chemical environments and possess high durability. To avoid the high
cost of commercial ceramic membranes, recently, a significant improvement has
been accomplished in developing them using low-cost alternative materials and
their appli... hiện toàn bộ
