In the chemical and pharmaceutical industries, FKM is a good solution for applications with nonpolar solvents
, aliphatic compounds, fats and oils.
It has been used as a polarity index for solvents (polar solvents [epslion] > 20, nonpolar solvents
[epslion] < 20).
Then the sorption of a mixture of polar and nonpolar solvents
is also investigated, with the sorption of each component of the mixture measured quantitatively.
Polar molecules are soluble in polar solvents and nonpolar molecules are soluble in nonpolar solvents
The most important of these is the omnipresent water, which stabilizes polar species--especially ions--in nonpolar solvents
and hence shifts the acid--base equilibria leading to erroneous results in the measurements of acidity or basicity.
These TPUs feature good balance of resistance to fuels, oils and most nonpolar solvents
often found in industrial work environments, as well as high compressive strength, low compression set, low gas and vapor permeability and low extractability levels.
Using computer simulations of water and five nonpolar solvents
, they calculated "the likelihood of finding, at an arbitrary point in the solvent, an atomic-sized cavity that could accommodate the solute.
Highly polar solvents such as alcohols and glycol ethers have low resistances, and nonpolar solvents
such as hydrocarbons have very high resistances.
, such as chloroform and EA-yielded fibers with an average diameter of 8-9 [micro]m, which is a significant increase.
It is scattered and mostly limited to mixtures of nonpolar solvents
New fluorosilicone compounds and copolymers are being developed with improved resistance to the traditional materials, such as fuels, nonpolar solvents
and hydraulic fluids, and with reduced swelling in materials such as ketones and esters.
The dielectric properties of polyolefins and their nonpolar solvents
result in the need to use additives that enhance the conductivity of the spinning melts or solution (4), (5).
