Radiation vulcanization of hydrogenated acrylonitrile butadiene rubber (HNBR)

Journal of Applied Polymer Science, 1994
AbstractRaw polymer and compound of hydrogenated acrylonitrile butadiene rubber (HNBR) were subjected to γ‐ray irradiation. Crosslinking was found to be the main chemical reaction induced by irradiation; the ratio of chain scission to crosslinking as well as the does at which gelation occurred were determined from gel content measurements to be 0.41 ...

Dynamically vulcanized blends of oil‐resistant elastomers with HNBR

Journal of Applied Polymer Science, 2004
AbstractDynamic vulcanizates were produced from hydrogenated nitrile rubber (HNBR) and three different oil‐resistant elastomers. These are polychloroprene (CR), expoxidized natural rubber (EIR), and carboxylated nitrile rubber (XNBR). These elastomers are dispersed and crosslinked during mixing with HNBR.

Hydrogenated NBR (HNBR) in Power Steering Hose

Polymers and Polymer Composites, 1997
This paper considers the relative performance of HNBR, NBR, CSM and CM Elastomers in a power steering environment. Also discussed are the effects of oxidised fluids and additive packages on the elastomer compound. The paper highlights recent changes in requirements for hoses in power steering applications and describes how HNBR can help hose ...

Study of structure and properties for HNBR/OMMT nanocomposite materials

2011 International Conference on Materials for Renewable Energy & Environment, 2011
The HNBR/OMMT nanocomposite materials are prepared by molten intercalation method using hydrogenated nitrile butyl rubber (HNBR) and organic montmorillonite (OMMT) as raw materials. Three kinds of OMMT precursors and two kinds of vulcanization agents are investigated in the synthesis of HNBR/OMMT materials.

Polyblend Systems of Polyurethane and HNBR Elastomers (Peroxide Cure)

International Journal of Polymeric Materials, 2001
The blends of polyurethane elastomer (AU) with hydrogenated nitrile rubbers (HNBR) prepared by different blending techniques and different blend ratios have been studied. The processability and weather resistant properties of polyurethane elastomer was improved by blending with HNBR.

3D Raman images of rubber blends (IR–HNBR)

Vibrational Spectroscopy, 2008
The morphology of rubber blends was studied by means of confocal Raman spectroscopy, this latter being used as an imaging tool. Two immiscible rubbers were blended at different concentrations to test the ability of Raman spectroscopy for analysing a three-dimensional (3D) heterogeneous structure.

Study of the miscibility and mechanical properties of NBR/HNBR blends

Polymer Engineering & Science, 2004
Abstract In this study, hydrogenated acrylonitrile butadiene rubber (HNBR, ZETPOL‐2010L) and nitrile butadiene rubber (NBR, NIPOL‐DN4555) were blended at different ratios in a Haake melt blender at 130°C. The HNBR and the NBR were of very similar acrylonitrile content and Mooney viscosity.

Fatigue of HNBR - Effects of formulation and thermal aging

Fatigue du HNBR - effet de la formulation et du vieillissement thermique Cette thèse de doctorat s’intéresse à la fatigue des élastomères, et plus particulièrement des caoutchoucs nitrile hydrogénés (sigle HNBR en anglais). Les HNBR sont des élastomères de haute performance,classiquement utilisés pour des applications industrielles à ...
