Elastomeric materials for sealing devices operated in the Far North, including Republic of Sakha (Yakutia), must be resistant to working environments and have frost wear resistance with acceptable physical mechanical properties. Some listed properties are mutually exclusive not always achievable based on individual rubber. Thus, one promising method elastomeric is use rubber mixtures. In this s...

Elastomers and their composites are widely used in modern innovative technology: for the production of aviation automobile tires, anti-vibration elements (rubber, rubber-metal springs), dampers, elastomeric bearings. Also they shaft suspensions, as spacers between structural parts, supporting parts fasteners. Elastomeric structures have a high dynamic load, particular cyclic nature, which is ac...

The present article describes preparation, characterization, and physical properties of nanoparticles-filled composites consisting of multiwall carbon nanotubes (MWCNT) and styrene-butadiene rubber and nitrilebutadiene rubber. The reinforcing MWCNT fillers were synthesized by chemical vapor deposition on iron and cobalt catalysts supported by calcium carbonate substrates. These MWCNT were furth...

Nitrile-butadiene rubber (NBR) and another polymer with an excellent self-lubricating property are blended to develop a new kind of polymer used for water-lubricated stern bearings. The tribological performance of the new Polymer Blend of NBR (PBN), with the comparison of a rubber common used for most stern bearings, was studied using a stern bearing test rig of SSB-100. The results showed that...

While lithium metal anodes have the highest theoretical capacity for rechargeable batteries, they are plagued by the growth of lithium dendrites, side reactions, and a moving contact interface with the electrolyte during cycling. Here, we synthesize a non-porous, elastomeric solid–electrolyte separator, which not only blocks dendritic growth more effectively than traditional polyolefin separato...

Polymers are becoming the material of choice for high voltage outdoor insulators. However being mostly organic, they are susceptible to aging and degradation (weathering) due to environmental (and electrical) stresses. This necessitates the study of their long-term behavior. It is desirable to study the long-term performance of the insulators in the service environment under multistress conditi...

The aim of this work is to study the effect new modified ingredients on complex properties composite elastomeric materials. It was found that introduction into composition compositions enhances interfacial interaction at «rubber-filler» interface and formation additional bonds between rubber macromolecules functional groups, as a result which an improvement in observed. carbon groups oligomer, ...

The purpose of this study was to validate the elastomeric impression after temporary tooth separation as a method of cavitation detection in proximal caries lesions in primary molars with outer half dentin radiolucency. Fifty-one children (4-10 years old), presenting radiolucency in the outer half of the dentin at the proximal surfaces of primary molars and proximal anatomic contact with the ad...
