Rubber Compounds for Biodiesel & Alcohol Fuel E85

by Shi Hwang

WARCO BILTRITE has developed 60 & 70 duro NBR sheet rubber compounds, specially designed for alternative fuels: Biodiesel B20 & B100 and Alcohol fuel E85. Alternative fuels are increasing in interest as well as their demand worldwide.

Biodiesel is the name of a clean burning alternative fuel, produced from any fat or oil such as soybean oil, through a refinery process. Biodiesel contains no petroleum and can be used as a pure fuel. B100 is the term for the pure (100%) biodiesel. But biodiesel can be blended at any level with petroleum diesel to create biodiesel blend. B20 is a blend of 20% biodiesel with 80% petroleum diesel by volume. Biodiesel is simple to use, biodegradable, nontoxic and essentially free of sulfur and aromatics. It is registered as a fuel and fuel additive with EPA. It can be made available anywhere in the US.

E85 is an alcohol fuel mixture of 85% ethanol and 15% gasoline, by volume. It is widely used in Sweden and is becoming increasingly common in the United State, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production. The benefits of using this fuel include reduced emission greenhouse gas and some air pollutants.

WARCO BILTRITE compounds were conducted for immersion tests in B20, B100 & E85. The test results indicate that the compounds are compatible with the alternative fuels and seem to be suitable for B20, B100 & E85.

However, it is recommended that any specific application should not be undertaken without evaluation for suitability. No guarantee is expressed or implied as to results that will be obtained by the end-user.
