1,3-Butadiene (BD), a gas used widely in production and synthesis of rubber, plastics, and resins, is metabolized to three different epoxide metabolites: butadiene monoxide (BMO), butadiene bisoxide (BBO) and epoxybutanediol (ED). We have examined the role of stereochemistry in the chemical and enzyme-mediated conjugation of R- and S-BMO; RR-, SS-, and meso-BBO; and SR-, RS-, RR-, and SS-ED wit...

Thermoplastic rubbers are materials that combine the characteristics of good processability of thermoplastics with the physical properties of vulcanized rubber. SEBS is a SBS which has been subjected to a hydrogenation process, through the polybutadiene chain is eliminated. This new rubber has a high resistance to environment, temperature, UV radiation, etc. without losing the properties of a t...

Rubber-filler composites are a key component in the manufacture of tyres. The filler provides mechanical reinforcement and additional wear resistance to the rubber, but it in turn introduces non-linear mechanical behaviour to the material which most likely arises from interactions between the filler particles, mediated by the rubber matrix. While various studies have been made on the bulk mecha...

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...

This work investigates the industrial production of styrene-butadiene rubber in a continuous reactor train, and proposes a soft sensor for online monitoring of several processes and polymer quality variables in each reactor. The soft sensor includes two independent artificial neural networks (ANN). ThefirstANNestimatesmonomer conversion, solid content, polymer production, average particle diame...

Along with the developing technology in rubber industry, use of natural and synthetic rubbers as well liquid has increased significantly recent years. The formulation tread compound, which directly affects performance a tire, is generally produced from rubbers. Intensive scientific studies have been carried out on because they reduce consumption process oils used tire production phase increase ...

Abstract The environmental impact of rubber waste can be reduced by extending the lifetime products. It achieved developing graphene/rubber nanocomposites with good abrasion resistance. In this paper, we investigated how mixing technologies influence mechanical properties rubber. We added various amounts (0, 1, 5 and 10 phr) graphite graphene to mixtures using a two-roll mill, an internal mixer...
