Properties and Degradation of Nitrile Rubber
2020Nitrile rubber vulcanizates containing medium nitrile proportions and a small amount of fillers, offer considerable resistance to degradation by radiations. Modification of plastics, such as polyvinyl chloride, acrylonitrile butadiene styrene, and phenolic resins by nitrile-butadiene rubbers (NBR) results in highly improved performances of the end ...

Nitrile Rubber-Polyvinylchloride Blends
Rubber Chemistry and Technology, 1962Abstract Vulcanizable blends of nitrile rubber and Polyvinylchloride combine excellent weather resistance with the low swelling in petroleum solvents of the nitrile rubbers. The Polyvinylchloride functions as a reinforcing agent and increases the hardness, modulus and tensile strength of the material. The principal disadvantages of the addition

Vulcanization and properties of hydrogenated nitrile rubber/nitrile rubber blends
The HNBR/NBR blends were prepared at ratios of 100/0, 90/10, 80/20 and 70/30 (wt%). The compounds by using a two-roll mixing mill at various ratios filled with two types of carbon black loading, GPF N-660 and SRF N-774 (fixed at 50 phr) were cured by three vulcanization systems: conventional vulcanization, efficient vulcanization and peroxide ...openaire +1 more source
Investigation of Abrasion of Nitrile Rubber
Rubber Chemistry and Technology, 1984Abstract Abrasion of NBR appears as a dry (particulate) wear, similar to unfilled BR, NR, and SBR, and filled BR. The abraded surface seems textured on two scales: that of the ridges of the abrasion pattern and that of small particles of debris.

Advances in Nitrile Rubber Technology
Rubber Chemistry and Technology, 1978Abstract Considerable advances have been made in NBR technology and still more are possible. The heat resistance of NBR has been raised so that it will with-stand 150°C in air for short periods, instead of 120°C. There is potential in the polymer backbone for still greater stability. It has been demonstrated that the ozone resistance of NBR can

Modelling the permeability of nitrile rubber
2016Elastomer seals are widely used in the oil and gas industry and form small but crucial parts of critical mechanical and electronic components. Ideally, to prevent damage to such components, the seals should act as impermeable barriers. However, under the high pressures and temperatures found downhole, they are liable to suffer two main types of ...

Scrap rubber recycling in nitrile rubber composites
2020In this study, scrap rubber were recycled by blending with nitrile rubber composites, having carbon black as filler. Resulting composites have been investigated, in terms of Theological and dynamic-static mechanical properties as well as their dimensional stabilities in organic solvents, as a function of carbon black-ground rubber compositions together
