Compression stress relaxation in carbon black reinforced HNBR at low temperatures
(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. ... -
Determining the PE fraction in recycled PP
(Peer reviewed; Journal article, 2021)The presence of a polyethylene (PE) fraction in recycled polypropylene (PP) will influence the processing as well as mechanical and thermal properties of recycled polypropylene. The objective of this work has been to compare ... -
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
(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 ... -
The effect of hydrocarbon ageing on the mechanical properties, apparent crosslink density and CO2 diffusion of a hydrogenated nitrile butadiene rubber (HNBR)
(Peer reviewed; Journal article, 2015)The effect of ageing in a sweet oil environment on the tensile properties, apparent crosslink density, CO2 diffusion and Shore hardness of a typical carbon black reinforced hydrogenated nitrile butadiene rubber (HNBR) is ... -
Elastic recovery after compression in HNBR at low and moderate temperatures: Experiment and modelling
(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 ... -
Experimental set-up for determination of the large-strain tensile behaviour of polymers at low temperatures
(Journal article; Peer reviewed, 2016)In this study, we present a method to determine the large-strain tensile behaviour of polymers at low temperatures using a purpose-built temperature chamber made of polycarbonate (PC). This chamber allows for several cameras ... -
Long-term ISO 23936-2 sweet oil ageing of HNBR
(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 ... -
Material characterisation and failure envelope evaluation of filament wound GFRP and CFRP composite tubes
(Peer reviewed; Journal article, 2014)The full procedure for material characterisation of filament wound composite pipe is reported. Two different typologies of composite were used in order to evaluate the performance of the developed test methodology. Test ... -
The mechanical properties of a model hydrogenated nitrile butadiene rubber (HNBR) following simulated sweet oil exposure at elevated temperature and pressure
(Peer reviewed; Journal article, 2015)A typical carbon black reinforced hydrogenated nitrile butadiene rubber (HNBR) was exposed to a mix of hydrocarbons (toluene, heptane and cyclohexane) at elevated temperatures and pressure in order to chemically age the ... -
The low temperature crystallization of hydrogenated nitrile butadiene rubber (HNBR)
(Journal article; Peer reviewed, 2018)HNBR was analyzed following low temperature storage (between 0 °C and −50 °C) in order to measure the effects of cold crystallization during exposure close to, and below, the glass transition temperature (Tg). Differential ...
