The use of fluorinate ethylene propylene copolymers (FEP) as an alternative to polyethylene tetrafluoride (PTFE/Teflon) was investigated using nanomechanical characterization techniques including nanoindentation and nano-dynamic mechanical analysis (DMA). PTFE is commercially relevant because of its hydrophobicity, inert reactivity, heat resistance, and mechanical properties Despite PTFE’s desirable materials properties for various applications, it cannot be processed via extruders due to its high viscosity, and thereby making it difficult to mold PTFE into complex shapes via injection molding. FEP has similar properties to those of PTFE. Therefore, FEP is being investigated as an alternative to PTFE because the use of FEP in place of PTFE would drastically reduce manufacturing costs by enabling the use of continuous processing techniques. The mechanical properties of both FEP and PTFE were compared in application oriented nanoindentation testing in order to better understand if FEP could replace PTFE in certain applications.
