Temperature-mediated microstructure evolution and densification mechanism of F2314 fluoropolymer binder during warm isostatic pressing

Key Points

• The study aims to examine how temperature influences the microstructure and densification mechanisms of the F2314 fluoropolymer binder during processing.
• Characterization of microstructure changes during warm isostatic pressing at varying temperatures.
• Analysis of densification mechanisms focused on particle interlocking and chain interpenetration.
• Comparison of mechanical properties before and after processing.
• Higher temperatures facilitate a transition from particle interlocking to chain interpenetration during densification.
• Improved microstructure leads to significantly increased density of the binder.
• Mechanical strength of the F2314 fluoropolymer binder is enhanced through the warming process.
