High temperature stability of hydrogenated nitrile butadiene rubber (HNBR) for sealing applications
The low temperature crystallization of hydrogenated nitrile butadiene rubber (HNBR)
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 scanning calorimetry (DSC), dynamic mechanical thermal analysis (DM...
Feasibility of using microencapsulated phase change materials as filler for improving low temperature performance of rubber sealing materials
Compression stress relaxation in carbon black reinforced HNBR at low temperatures
Elastic recovery after compression in HNBR at low and moderate temperatures: Experiment and modelling
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 set property of a hydrogenated nitrile butadiene rubber (HNBR) at temperatures a...
Thermomechanical properties of zirconium tungstate/hydrogenated nitrile butadiene rubber (HNBR) composites for low-temperature applications
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 subjected to decreases in temperature. Composites of hydrogenated nitrile butadie...
The effect of hydrocarbon ageing on the mechanical properties, apparent crosslink density and CO2 diffusion of a hydrogenated nitrile butadiene rubber (HNBR)
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 presented. Different ageing conditions yielded materials with different propert...
The mechanical properties of a model hydrogenated nitrile butadiene rubber (HNBR) following simulated sweet oil exposure at elevated temperature and pressure
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 material. The effect of this exposure on the mechanical properties is reported; ...
