Characteristic
Chemical composition: FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene, and its trade name includes Teflon ® FEP, also known as perfluoroethylene propylene (F46).
Physical properties: Density 2.15g/cm ³, crystalline melting point 304 ℃, continuous use temperature range -200 ℃ to 205 ℃.
The dielectric constant is low (2.1), and the mechanical strength is higher than that of polytetrafluoroethylene (PTFE), but the operating temperature is about 50 ℃ lower than PTFE.
Application Area
Industrial field: chemical pipeline lining, wire and cable insulation layer, semiconductor injection molded parts, etc.
Electronic technology: Micro electronic packaging (such as LED brackets), micro nano pattern preparation in nanoimprint technology.
Special materials: After composite modification, they can be used in high-frequency breakdown, thermal management and other scenarios (such as FEP/AlN composite materials).
