Anisotropy of the internal damage caused by imposed deformation, which is called stress-softening or Mullins effect, was investigated for a carbon-black (CB) filled styrene butadiene rubber (SBR/CB) sequence two tensile measurements. A wide-width pristine sheet specimen satisfying pure shear (planar) stretching geometry first subjected to single loading-unloading cycle with maximum stretch (λm)...

In this paper, three composite agents (i.e. emulsified asphalt, EA; styrene butadiene rubber, SBR; rubber powder, RP) were employed to modify the cement stabilized macadam (CSM) for optimal design of semi-rigid base materials. The feasibility utilizing EA/SBR/RP composites in is investigated from perspectives modification mechanism and durability performance. To investigate effects different mo...

Fly ash (FA) is produced as a waste byproduct during the burning process of coal in thermal power plants whose cost is primarily associated to cleaning and transportation. It possesses mechanical properties on account of its constituents like silica and alumina. The use of FA as filler in styrene butadiene rubber (SBR) was of researchers’ interest to reinforce and/or to reduce product cost. In ...

OBJECTIVES This study evaluated the mortality experience of workers from the styrene-butadiene rubber industry. Concerns about a possible association of 1,3-butadiene and styrene with lymphohaematopoietic, gastrointestinal, and lung cancers prompted the investigation. METHODS A retrospective follow up study was conducted of 15,649 men employed for at least one year at any of eight North Ameri...

Thermogravimetric methods with internal polymer standards have successfully quantified environmental tire and road wear particle (TRWP) concentrations. However, TRWP quantification in matrices via pyrolysis-gas chromatography-mass spectrometry (py-GC-MS) using butadiene rubber (BR) styrene-butadiene (SBR) marker 4-vinylcyclohexene (4-VCH; 1,4-butadiene-1,4-butadiene dimer) may be uncertain beca...

Silicon anodes require polymer binder systems that are both mechanically robust and electrochemically stable, to accommodate the dramatic volume expansion experienced during cycling operation. Herein, we report use of a poly(acrylic acid)-grafted styrene–butadiene rubber (PAA-g-SBR) with 80% partially neutralized Na-PAA as system for silicon-graphite anodes. The PAA-g-SBR graft copolymer was sy...

this study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. starch-based sbr1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (plastograph brabender).the content in starch was varied from 0 to 50 phr. the effect of starch content on the rheological behavior was evaluated through...

Sulfur (S) cross-linking styrene butadiene rubber (SBR) foams show high shrinkage due to the cure reversion, leading to reduced yield and increased processing cost. In this paper, double cross-linking system by S and dicumyl peroxide (DCP) was used to decrease the shrinkage of SBR foams. Most importantly, the synergy of double cross-linking agents was reported for the first time to our knowledg...
