The Influence of Cure Characteristics and Crosslink Density of Virgin Acrylonitrile Butadiene Rubber/Recycled Acrylonitrile Butadiene Rubber (vNBR/rNBR) Blends

Key Engineering Materials, 2013
Cure characteristics and crosslink density of virgin acrylonitrile butadiene rubber/recycled acrylonitrile butadiene rubber (vNBR/rNBR) blends were studied. Three different size ranges of rNBR particles, i.e., 150 - 350 μm, 2.0-15.0 mm, and 5-10 cm were used in this study.

Comparison properties of natural rubber/virgin acrylonitrile–butadiene rubber and natural rubber/recycled acrylonitrile–butadiene rubber blends

Iranian Polymer Journal, 2015
Cure characteristics, mechanical and morphological properties of natural rubber/virgin acrylonitrile–butadiene rubber (NR/NBRv) and natural rubber/recycled acrylonitrile–butadiene rubber (NR/NBRr) blends were investigated. The properties of NR/NBRv and NR/NBRr blends were studied at five different ratios of virgin and recycled NBR content [i.e., 95/5 ...

Hydrogenation of acrylonitrile–butadiene rubber latexes

Journal of Applied Polymer Science, 2003
AbstractThe hydrogenation of acrylonitrile–butadiene rubber (NBR) latex was carried out by a system consisting of hydrazine hydrate and hydrogen peroxide, with boric acid as catalyst. Highly saturated hydrogenated NBR (HNBR) latex was obtained through the optimization of the reaction conditions. The dried HNBR was found to be heavily gelled.

Polyacrylonitrile determination in acrylonitrile‐butadiene rubber

Journal of Applied Polymer Science, 1997
Acrylonitrile content from copolymer of acrylonitrile-butadiene has been studied combining vibrational spectroscopy and a nuclear technique. On the basis of the results obtained, it has been proven that these techniques can clearly be an asset to determine acrylonitrile content in rubber materials without prior separation and in a nondestructive fast ...

Reaction of ozone with natural hevea and acrylonitrile‐butadiene rubbers

Journal of Polymer Science, 1956
AbstractThe physical changes that occur when ozone reacts with unvulcanized rubber or unstretched vulcanizates have been studied. The speed of reaction is controlled by diffusion of gas into the rubber; as a consequence, initial products formed near the surface are subjected to further action by ozone. To minimize this possibility experiments have been

Ground rubber/acrylonitrile–butadiene–styrene composites

Composites Science and Technology, 2007
Abstract A range of ground rubber (GR)/acrylonitrile–butadiene–styrene (ABS) composites were developed that contained untreated and various treated rubber particles. The tensile properties of the composite materials were significantly improved over the untreated GR/ABS sample either by a two-step treatment process involving surface chlorination of ...

ACRYLONITRILE–BUTADIENE RUBBER STABILIZED BY METHACRYLAMIDES AS ANTIOXIDANTS

Polymer-Plastics Technology and Engineering, 2000
Methacryloyl chloride was reacted with 4-amino and 4-thiophenols to provide the corresponding methacrylamides. These compounds were incorporated in NBR mixes to be evaluated as antioxidants for NBR oil-seal products in comparison with the industrial antioxidant phenyl-B-naphthylamine (PBN).

Toughening epoxy resins with solid acrylonitrile-butadiene rubber

Polymer International, 2000
The feasibility of using solid acrylonitrile–butadiene rubbers (NBR) with 19 and 33% w/w acrylonitrile to toughen diglycidyl ether of bisphenol A (DGEBA) epoxy resins has been investigated. Thermal analysis experiments revealed a two-phase morphology of these rubber-modified epoxies.

Study of hydrogen sulfide effect on acrylonitrile butadiene rubber/hydrogenated acrylonitrile butadiene rubber for sealing application in oil and gas industry

Journal of Applied Polymer Science, 2022
AbstractAcrylonitrile Butadiene Rubber (NBR) and Hydrogenated Acrylonitrile Butadiene Rubber (HNBR) have been widely used in many sealing applications for downhole operation. To build practical operation limits for NBR and HNBR packer elements, it is required to fill the gap between laboratory‐scale tests and field operation experience on how packer ...
