Effect of Methanol Volume Fractions in Gasoline on AntiSwelling Property of Rubber Materials
XIONG E, YAN Feng, ZHANG Wenpeng
Because of inherent characters of rubber materials, there exists some differences on antiswelling property of rubber materials in gasoline with different methanol volume fraction. Immersion tests in gasoline 93# or gasoline with different methanol proportions are conducted to show the antiswelling property of 3 rubber materials commonly used in motor vehicles. The results show that silicone rubber has better antiswelling property in gasoline with high methanol proportion; on the contrary, fluorine rubber has good resistance to swelling in low proportionmethanol gasoline; Nitrile Rubber has good antiswelling property in all gasoline with different proportion of methanol.
