CHEMICAL RESISTANCE OF HNBR AND NBR IN PROPYLENE

Rubber Chemistry and Technology
ABSTRACT The chemical resistance of HNBR and NBR in propylene is considered as no resistance by many chemical compatibility handbooks and industry chemical resistance tables and charts. This situation drives the change of the elastomer compounds from cheap HNBR/NBR to expensive fluoroelastomer for applications involving propylene.

New Developments for Surviving Aggressive Environments with HNBR

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">This paper will discuss new developments that enhance the heat and chemical resistance of rubber articles made with Hydrogenated Acrylonitrile Butadiene Rubber (HNBR). Results of long term aging studies in hot air, lubricating oils, and oxygenated fuels will be presented. The work will be oriented to seal, hose and

Multifunctional and specific interactions of CNTs in NBR and HNBR

World Journal of Engineering, 2014
There are different techniques in practice to disperse multiwalled carbon nanotubes (MWCNTs) in elastomers. In the present work, commercially available MWCNTs NANOCYL NC 7000™ are used as filler. A synthetic Nitrile Butadiene Rubber (NBR) and Hydrogenated Nitrile Butadiene Rubber (HNBR) were used as polymer matrix for the composites prepared by melt ...

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 ...

Thermal and radiation behaviour of HNBR and CSPE blends

Polymer, 2000
Abstract The changes in crosslinking, chlorine or sulphur content and unsaturation were determined for three concentrations of hydrogenated acrylonitrile–butadiene rubber (HNBR)/chlorosulfonated polyethylene (CSPE) blends (25:75, 50:50 and 75:25 wt%), and for their individual components.

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.

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 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.
