Matériaux & Techniques, 1990
The automotive industry is the main area where technical elastomers are used. In recent, the conditions to which the elastomeric parts are subjected, have become more severe because of higher underbonnet temperature and the need for higher standards of quality and reliability.

Properties of ASA/SAN/NBR ternary blends: effect of AN content in NBR
Plastics, Rubber and Composites, 2014Nitrile–butadiene rubbers (NBRs) with different acrylonitrile (AN) contents were used to toughen acrylonitrile–styrene–acrylic terpolymer/styrene–acrylonitrile copolymer (ASA/SAN) blends. The properties of the ASA/SAN/NBR ternary blends were investigated via dynamic mechanical analysis, heat distortion temperature, Fourier transform infrared ...

Journal of Applied Polymer Science, 1986
AbstractStudies conducted on butadiene–acrylonitrile copolymer (NBR)/poly(vinyl chloride) (PVC) blends at different temperatures indicate that an optimum temperature exists for the formation of a particular blend. The mechanical properties of the blends confirm this observation.

Morphology and physical properties of SAN/NBR blends: The effect of AN content in NBR
Journal of Applied Polymer Science, 2000Poly(styrene-co-acrylonitrile) (SAN), of which the content of acrylonitrile (AN) repeating unit is 32 wt % (SAN32), was blended with poly(butadiene-co-acrylonitrile) (NBR). The effects of AN repeating unit content in NBR on the miscibility, morphology, and physical properties of SAN32/NBR (70/30 by weight) blends were studied.

Crosslinking of PVC and NBR blends
Polymer International, 1993Abstract The purpose of our work is to control the interfacial bonds between PVC and NBR using the ammonium salts of triazine thiols and dithiodimorpholine (DTDM) and thereby reveal the relation between the interfacial bonds and the final mechanical properties of products.

Total Thermal Analysis of NBR Vulcanizates
Rubber Chemistry and Technology, 1978Abstract NBR vulcanizates of different nitrile content can be identified by total thermal analysis. Vulcanizate composition analysis is complicated because of formation of carbon from NBR. The difficulty can be obviated by identifying the specific type of NBR by Tg and making allowances for the known amount of carbon formation for that specific

Solvent Crack Growth in NBR Rubber
Rubber Chemistry and Technology, 1976Abstract The solvent crack growth of rubber compounded with various carbon blacks or calcium carbonate was investigated. It was found that the rate of crack growth of filler-loaded rubber was linearly related to extension ratio in a manner similar to gum vulcanizates.

A Study of Mechanical and Optical Properties of an Alternating NBR and an Emulsion NBR
Rubber Chemistry and Technology, 1973Abstract At low elongation, over the range of temperatures and frequencies studied, the dynamic properties (elastic modulus and loss factor) and activation energy for the glass-rubber transition are the same for highly alternating and emulsion copolymers of acrylonitrile and butadiene.

Anàlisi tèrmica i morfològica de mostres elastomèriques de cautxú NBR i NBR/PVC
2003Aquest projecte final de carrera analitza el comportament tèrmic i morfològic de mostres elastomèriques de cautxú nitril (NBR) i NBR/PVC. L’estudi compara la seva estabilitat tèrmica, la influència dels antioxidants, la degradació controlada i la consistència estructural. Les tècniques emprades inclouen calorimetria diferencial (DSC), termogravimetria (

Advances in Nitrile Rubber (NBR)
1987Nitrile rubber (NBR) is the accepted polymer for oil, solvent, fuel and grease resistance. Over 300 grades are now commercially available from which the rubber industry can choose polymers that will satisfy the most stringent demands of modern rubber mixing and processing methods.
