The low temperature crystallization of hydrogenated nitrile butadiene rubber (HNBR) [PDF]
Polymer Testing, 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).

Abstract The thermal degradation of hydrogenated nitrile-butadiene rubber (HNBR)/clay and HNBR/clay/carbon nanotubes (CNTs) nanocomposites was investigated with thermogravimetric analysis (TGA) by using Kissinger method, Flynn–Wall–Ozawa method and Friedman method. The activation energy sequence of HNBR and its nanocomposites is HNBR/clay/CNTs > HNBR/

Journal of Applied Polymer Science, 2014
ABSTRACTThis article focuses on the reinforcement of hydrogenated acrylonitrile butadiene rubber (HNBR) by cotton fiber as natural reinforcing filler. The effect of fiber alignment on the properties of HNBR compounds and vulcanizates is investigated. Properties of interest include rheological behavior, cure, tensile, abrasion, and dynamic mechanical ...

Properties of POSS/HNBR Elastomer Nanocomposites
Materials Science Forum, 2012A series of composite materials containing polyhedral oligomeric silsesquioxanes (POSS) and hydrogenated butadiene-acrylonitrile rubber (HNBR) were prepared. The goal of the work was to evaluate the effect of the type and reactivity of functional groups in the POSS cage on properties of the resulting elastomeric nanocomposites.
