Flexible forming is a sheet metal forming process with the application of soft material tooling. In this study, flexible (silicone rubber, SR, and styrene butadiene rubber, SBR) and semi-rigid (polyamide 66, PA) polymeric materials were adopted to make several upper dies which were used in combination with aluminium lower dies. Stamping operations were performed on a thin aluminium alloy sheet ...

Conventional bearing systems and materials, which are important components of machine elements, have often failed to fulfil requirements, especially in places where sealing is required. In such cases, sliding bearings with PTFE- NBR-based polymer elastomer materials operating water or oil preferred. this study, the performance two alternative rubber-based synthetic styrene butadiene rubber (SBR...

Abstract Rubber blending has been widely used to improve various properties in finished rubber products. The purpose of this paper is investigate the effect filler size, type, concentration, and surface treatment on mechanical, swelling, dielectric, morphology ethylene propylene diene (EPDM)/styrene-butadiene (SBR) blend nanocomposites filled with alumina (Al 2 O 3 ) nanoparticles. Bis-(3-(trie...

The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and styrene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known car...

The co-pyrolysis of various biomasses mixed with two types plastic waste was investigated in this study. Mixture M1 consisted 30% m/m styrene–butadiene rubber (SBR), 40% polyethylene terephthalate (PET), and polypropylene (PP). M2 PET, PP, acrylonitrile–butadiene–styrene copolymer (ABS). SBR, ABS, PP used study were from the automotive industry, while PET originated scrap bottles. Co-pyrolysis ...

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...

A comparative study has been done to investigate the effect of carbon black (CB) and fumed silica (Si) on physico-mechanical thermal properties Bagasse/styrene-butadiene rubber (B-SBR) composites. Based incorporation 25 phr from natural ground bagasse powder (GBP) as a supplement reinforcing filler in styrene butadiene (SBR) vulcanizates, two identical sets formulations have prepared using diff...

The influence of styrene butadiene rubber (SBR) or low-density polyethylene (LDPE) polymers on the characteristics local asphalt binder was analyzed to characterize rheological properties. results indicated that SBR LDPE increased softening point. point enhanced by around 35% when 9% used in comparison unmodified asphalt, while there a 15% increment used. also decreased penetration rate. decrea...

1,3-Butadiene is a highly volatile gas that is used in the production of synthetic rubber; the major end use of the synthetic rubber is automobile tires. 1,3-Butadiene is also used for the production of high impact polystyrene and acrylonitrile-butadiene-styrene (ABS) resin plastics The predominant source of 1,3-butadiene in the atmosphere is industrial releases, which can occur during manufact...

The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...
