Oil-Resistant Elastomers with Low Permeability to Nitrogen

Abstract

The purpose of this work was to reduce the nitrogen gas transmission rate (GTR) and permeability coefficient of oil-resistant elastomers without adversely affecting other physical properties. This was accomplished through the use of various fillers of proper size and shape to produce a blocking effect, thus reducing gas transmission through the polymer film. Carbon black and most nonblack fillers produced only a small reduction in GTR, whereas platelike mica and graphite fillers produced significant reductions of as much as 78 percent. These reductions in GTR were achieved without serious loss of oil resistance or compression set; but, in some cases, loss in flexibility at low temperatures was noted.
