Recently, the use of new fuels for the automobile is noticed from the viewpoint of the environmental problem and rise in price of the petroleum. As new fuels for the automobile, bioethanol produced from the plants, BDF (Bio-Diesel Fuel) produced from vegetable oil such as soybean oil, and ETBE( Ethyl Tertiary Butyl Ether ) synthesized from ethanol and isobutene have been used practically.
This review describes the influence of new fuels on rubber materials ( FKM, NBR, HNBR, ACM, Q, ECO ). The phys-ical property change of rubber materials by the dipping in ETBE is slight. On the other hand, BDF and bioethanol give the bad effects in rubber materials, however the effects are little for HNBR, FKM, and ECO.
