EVM/HNBR Elastomer Blends for Automotive Applications
SAE Technical Paper Series, 2004<div class="htmlview paragraph">Hydrogenated acrylonitrile butadiene rubber (HNBR) compounds provide excellent mechanical properties, as well as heat, oil and fluid resistance in many demanding automotive applications. Ethylene vinyl acetate copolymer (EVM) compounds possess excellent compression set, heat resistance and processability.

Thermal and radiation behaviour of HNBR and CSPE blends
Polymer, 2000Abstract 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.

HNBR for Oilfield Applications
CORROSION 1990, 1990Abstract Test data indicate that highly saturated nitrile rubber (HNBR) can be used in high temperatures, and aggressive environments. The aggressive environments contain gas mixtures of methane, carbon dioxide, hydrogen sulfide, and other hydrocarbons.

CHEMICAL RESISTANCE OF HNBR AND NBR IN PROPYLENE
Rubber Chemistry and TechnologyABSTRACT 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.

Multifunctional and specific interactions of CNTs in NBR and HNBR
World Journal of Engineering, 2014There 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 ...

Ozone Resistance of Highly Saturated Nitrile Rubber (HNBR)
Journal of Elastomers & Plastics, 1992Ozone resistance of highly saturated nitrile rubber (HNBR) has been studied; the effect of hydrogenation progress of HNBR was evaluated at various ozone test conditions such as static, dynamic, and sequential condi tions. Dependence of its hydrogenation progress on ozone resistance is discussed by using parameters of Ii, Iodine value ...

The Status of HNBR in the West European Automotive Industry
SAE Technical Paper Series, 1989<div class="htmlview paragraph">Hydrogenated nitrile rubber (HNBR) is presented with respect to its principal technical features and market forecast. Being mainly an elastomer for powertrain applications HNBR, especially in cars with increased service temperatures, must be seen in connection with various service fluids.
