Technical Note: Nitrile Rubber and B20 Biodiesel Blends

A significant amount of new testing data on nitrile performance in U.S. heating oil equipment with biodiesel meeting today’s stringent ASTM standards is now available. This recent testing shows common nitrile elastomers in typical heating oil burner pumps in the U.S. perform the same or better using B20 than those using conventional No. 2 heating oil. The validity of this testing is supported by elastomer manufacturers marketing B-100 nitrile which could, if appropriate, be used by burner manufacturers. See Technical note here.
