Compatibility of sealing materials with biofuels and biodiesel-heating oil blends
- Changes in fuel composition and the introduction of alternative fuels often create problems of degradation in materials. The objective of this research is to study the interaction of the sealing materials FKM, EPDM, CR, CSM, N8R, IIR, VMQ, FVMQ and PA and biofuels such as non-aged and 2 year aged biodiesel (FAME), E1 0 (fuel with 10% ethanol, E85 (fuel with 85% ethanol} and non-aged and 1 year aged 810 (heating oil with 10% biodiesel) in comparison with premium grade fuel without ethanol. Exposure tests were performed with test specimens at 20 °C, 40 oc and 70 oc for 84 days to document the changes in mass, volume and tensile properties. The sealing materials FKM, FVMQ and PA were evaluated as resistant in E10, and FVMQ, VMQ and PA as resistant in E85 at 20 oc and 40 oc. S welling resulted from the high absorption by the elastemers CR, CSM, EPDM, IIR and N8R in comparison to their dissolution in non-aged biodiesei at 40 °C. FKM was still resistant in aged biodiesei at 40 oc but only toChanges in fuel composition and the introduction of alternative fuels often create problems of degradation in materials.

FKM was still resistant in aged biodiesei at 40 oc but only to a limited degree at 70 °C. The sealing materials CR, CSM, EPDM, IIR and N8R were damaged to a high extent in non-aged and aged 810. Of all the sealing materials, FKM and FVMQ showed high compatibility with these biofuels up to 70 °C.…
