Barrierity of hydrogenated butadiene-acrylonitrile rubber and butyl rubber after exposure to organic solvents.
Resistance of antichemical clothing primarily depends on the type of material it is made from, in particular on the type of polymer used for coating the fabric carrier. This paper reports on systematic investigations on the influence of the cross-linking density of an elastomer and the composition of a cross-linked elastomer on its resistance to permeation of selected organic solvents. Tests of...
متن کاملComparative Study of Butyl Rubber (IIR) and Bromobutyl Rubber (BIIR) based on FTIR, Dielectric and Thermal Studies
The study aims for a comparative study of butyl rubber (IIR) and bromobutyl rubber (BIIR) based on spectroscopic, dielectric and thermal characterization. Using FTIR, complete vibrational analysis of butyl rubber and bromobutyl rubber are made available which confirms their chemical structure and the functional groups present in them. The effect of microwave frequency, namely 10 GHz and 26 GHz ...
متن کاملsurveying the influence of reclaimed rubber and rubber powder on physical, dynamical and processing properties of nr/br compound
since reusing waste tire as a cheap filler is considerably high, in this study, recycled rubber to replace nr/br is used up to 15 phr and the positive and negative aspects of the rubber powder and reclaimed rubber in the physical, dynamical and processing properties are evaluated. the results showed that in the presence of recycled rubber, the cure rate, crack growth resistance, tear strength a...
متن کاملButyl rubber stoppers increase the shelf life of prereduced, anaerobically sterilized media.
Butyl rubber stoppers as compared with neoprene or black rubber stoppers significantly increased the shelf life of prereduced, anaerobically sterilized media for growth of obligately anaerobic bacteria.
متن کاملSuitability of butyl rubber stoppers for closing anaerobic roll culture tubes.
Stringently anaerobic bacteria have been successfully cultured in rubber-stoppered roll tubes. Stoppers of certain types of rubber are so permeable to oxygen that they are unsuitable (Hungate, J. Bacteriol. 86:848, 1963). Butyl rubber is less permeable to gases than are many other types. The permeabilities of butyl stoppers and a common laboratory type to gases concerned in anaerobic culture wo...
