Modern passenger car tire tread compounds usually consist of a polymer blend Solution Styrene-Butadiene Rubber (SSBR) and Butadiene (BR) in combination with silica/silane system. To further enhance the compatibility between nonpolar polar silica, different functional groups can be introduced at end or along chains. The influence such functionalization SSBR BR on processing behavior as well mech...

background: the measurement data regarding the influent and effluent of wastewater treatment plant (wwtp) provides a general overview, demonstrating an overall performance of wwtp. nevertheless, these data do not provide the suitable operational information for the optimization of individual units involved in a wwtp. a full-scale evolution of wwtp was carried out in this study via a reconciled ...

Abstract The flow curves of polymers often reveal the onset melt instabilities such as sharkskin, stick–slip, or gross fracture, in order increasing shear rates. focus this work lies application Göttfert sharkskin option to investigation styrene-butadiene rubber (SBR) compounds. consists highly sensitive pressure transducers located inside a slit die capillary rheometer. This tool allows detect...

In order to study the effect of UV aging on asphalt performance, four-component test, dynamic shear rheology and flexural creep stiffness test were combined with molecular dynamics simulation matrix rubber powder/styrene-butadiene rubber/polymerization. The properties phosphoric acid/epoxy resin modified before after analyzed, mechanism was discussed. Research shows that has better high low tem...

Polypropylene (PP) compounds with styrene–butadiene rubber residue (SBRr) from the footwear industry were produced, adding styrene-(ethylene–butylene)-styrene (SEBS) as a compatibilizer, 20% and 30% of styrene (St.). The PP/SBRr PP/SBRr/SEBS processed in co-rotating twin-screw extruder injection molded. addition SBRr did not compromise processability, torque melt flow index increased slightly c...

the polymeric and non-polymeric petrochemical wastes are environmentally unfavorable materials. we have to found a way to reuse these wastes in a safe manner. in styrene-butadiene rubber (sbr) production plant two major wastes are produced one is a fine rubber powder and the other is recycled n-methyl pyrrolidone (nmp). in high-density polyethylene (hdpe) production plant also a low molecular w...

Fused deposition modeling (FDM) is a rapidly growing 3D printing technology. However, printing materials are restricted to acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) in most Fused deposition modeling (FDM) equipment. Here, we report on a new high-performance printing material, polyether-ether-ketone (PEEK), which could surmount these shortcomings. This paper is devoted to...
