The effect of hot air exposure on the mechanical properties and carbon dioxide permeability of hydrogenated nitrile butadiene rubber (HNBR) with varying carbon black content
Alcock, Benjamin; Peters, Thijs; Tiwari, Avinash (Peer reviewed; Journal article, 2020)The effect of hot air exposure at 150ºC for up to 12 weeks (ca. 2000 h) on the properties of hydrogenated nitrile butadiene rubber (HNBR) compounds with varying degrees of carbon black content was investigated and re-ported ... -
Long-term ISO 23936-2 sweet oil ageing of HNBR
Akulichev, Anton; Alcock, Benjamin; Krauklis, Andrey; Tiwari, Avinash; Echtermeyer, Andreas (Peer reviewed; Journal article, 2021)A hydrogenated nitrile butadiene rubber (HNBR) compound is subjected to ageing in a simulated oil and gas environment in accordance with ISO 23936-2 standard at two elevated temperatures (130 °C and 150 °C) for a period ... -
Thermomechanical properties of zirconium tungstate/hydrogenated nitrile butadiene rubber (HNBR) composites for low-temperature applications
Akulichev, Anton; Alcock, Benjamin; Tiwari, Avinash; Echtermeyer, Andreas Thorsten (Peer reviewed; Journal article, 2016)Rubber compounds for pressure sealing application typically have inferior dimensional stability with temperature fluctuations compared with their steel counterparts. This effect may result in seal leakage failures when ...
