Compression stress relaxation in carbon black reinforced HNBR at low temperatures
Akulichev, Anton; Alcock, Benjamin; Echtermeyer, Andreas (Peer reviewed; Journal article, 2017)Findings of a study of stress relaxation behaviour of hydrogenated nitrile butadiene rubber (HNBR) at nominal compressive strains up to 0.4 and temperatures above and below the glass transition temperature Tg are reported. ... -
Elastic recovery after compression in HNBR at low and moderate temperatures: Experiment and modelling
Akulichev, Anton; Alcock, Benjamin; Echtermeyer, Andreas T. (Journal article; Peer reviewed, 2017-08)Elastic recovery after compression or compression set is one of the key indicators of elastomer performance in sealing applications, such as O-rings in flange joints. In this work, findings of a study of the compression ... -
HNBR elastomer composite with zero thermal contraction over a range of temperatures
Akulichev, Anton; Alcock, Benjamin; Protasov, Andrey; Markin, Pavel; Echtermeyer, Andreas (Peer reviewed; Journal article, 2019)Elastomers such as hydrogenated nitrile butadiene rubber (HNBR) are known to have inferior dimensional stability upon temperature changes compared to metallic materials. This can result in thermal contraction mismatches ... -
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 ...
