Effect of silanes as crosslinking agent with the NBR rubber
نویسندگان
چکیده
Silane coupling agent generally use as improve the properties of white filler use in rubber compound for better dispersion. Also silane coupling agent reacts with organic filler & polymer chain as crosslink. Here in this research study the crosslink density & swelling phenomena of silane participate in vulcanization process with Nitrile rubber compound. Also show the comparisons of carbon filled and silica filled NBR rubber compound crosslink density property. Silanes increase the viscosity of compound, crosslink density with low swlling resistance.

Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil
III To my mother and father IV ABSTRACT Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. This work therefore aimed at investigating the degradati...

One of the problems for use of rubber in various industries is surface tension at the surface of rubbers, which results in the crack on the surface, fracture of the rubber and reduces its life. These tensions are caused by contacting the rubber component with the metal surface and the friction between two surfaces. Roughness of the surface, the composition of the rubber compound, the environmen...

Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...
