1. Nitrile rubber and carboxylated nitrile rubber resistance to soybean biodiesel
Abstract Biodiesel has been considered a suitable substitute for petroleum diesel, but their chemical composition differs greatly. For this reason, biodiesel interacts differently than petroleum diesel with various materials, including rubbers. Therefore, the resistance of some elastomers should be thoroughly evaluated, specifically those which are commonly

2. Estudo das propriedades reológicas, mecânicas e de blindagem eletromagnética de misturas elastoméricas envolvendo borracha nitrílica (NBR) e borracha nitrílica carboxilada (XNBR)
Resumo Neste trabalho foram avaliadas as propriedades reológicas, mecânicas e de blindagem eletromagnética de misturas elastoméricas envolvendo borracha nitrílica (NBR) e borracha nitrílica carboxilada (XNBR) formuladas com 30 pcr de negro de fumo condutor. As proporções de NBR/XNBR estudadas foram 100/0, 80/20, 50/50, 20/80, 10/90 e 0/100. Os result

3. Compatibilization efficiency of carboxylated nitrile rubber and epoxy pre-polymer in nitrile/acrylic rubber blends
An investigation has been made of the effects from a compatibilizer, viz. carboxylated nitrile rubber (XNBR), on several properties of nitrile rubber (NBR) and acrylic rubber (ACM) blends, including curing characteristics, mechanical, dynamic mechanical and dielectric properties. The presence of XNBR until 10 phr resulted in an improvement of the ultimate te

4. Carboxylated nitrile butadiene rubber/hybrid filler composites
The surface properties of the OSW and NLS are measured with the dynamic contact-angle technique. The x-ray photoelectron spectroscopy (XPS) of the OSW reveals that the OSW possesses various reactive functional groups namely hydroxyl groups (OH). Hybrid filler from NLS and OSW were incorporated into carboxylated nitrile rubber (XNBR) to produce XNBR hybrid co

5. Obtenção e propriedades de nanocompósitos borracha/argila a partir de látices de borrachas comerciais e borrachas epoxidadas
Atualmente, nanocompósitos têm sido alvo de grande interesse científico e tecnológico. Além do negro-de-fumo e da sílica, materiais já consagrados como nanopartículas de reforço para uma grande variedade de borrachas, outras nanopartículas funcionalizadas têm sido o centro das atenções. Especialmente, nanopartículas bidimensionais (lâminas) e
