Effects of CO2 on polymeric materials in the CO2 transport chain: A review
Ansaloni, Luca; Alcock, Benjamin; Peters, Thijs (Journal article; Peer reviewed, 2020)The implementation of carbon capture and storage requires suitable solutions at all levels of the CO2 value chain, including the CO2 transport. A large number of studies in this area are dedicated to the characterization ... -
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.
