Investigation of Mechanical Stress and B10 Exposure on FKM Polymer

Mechanical stressMechanical stress often accelerates the failure of polymer materialsMaterials. The aim of this research is to study the interaction between the sealing materialSealing materials FKM and biofuelsBiofuels B10 (heating oil with 10% biodiesel). The mechanical stressMechanical stress test was carried out in a special apparatus. Both mechanical and non-mechanical stressMechanical stress tests were conducted on specimens at 20, 40, and 70 °C for 28 days to document changes in mass, volume, and tensile propertiesTensile properties. Both increasing temperatureTemperature and mechanical stressMechanical stress have a significant effect on the tensile strengthTensile strength of the FKM polymer when exposed to B10. The combination of increasing temperatureTemperature and mechanical stressMechanical stress induced rupture within 2 h. It was also established that FKM polymer with pre-exposure in B10 survived longer during mechanical stressMechanical stress compared to specimens exposed only to air. With the support of infrared (IR) spectroscopy, we were able to confirm the penetration of B10 into the FKM polymer.
