PTFE(Polytetrafluoroethylene) is the king of chemical resistance, high temperature resistance (260 ° C), and the lowest friction coefficient among all fluoroplastics. It is the benchmark of fluoropolymer family.
Choosing Reason: It requires extreme chemical and high temperature resistance, and a simple shape.
More info
PFA(Perfluoroalkoxy alkane) occupies almost all the excellent properties of PTFE, while also possessing the melt processability of thermoplastic. Therefore, it is called “meltable PTFE”. It has higher temperature resistance than FEP.
Choosing reason: Requires extreme chemical and high temperature resistance, complex shapes, high purity or transparency.
FEP(Fluorinated Ethylene Propylene) is a melt processable version of PTFE, but its maximum operating temperature is slightly lower (205°C). It is an economical alternative to PFA.
Choosing reason: Requires good chemical resistance, complex and transparent shapes, but limited budget and operating temperature not exceeding 205°C.
ETFE (Ethylene Tetrafluoroethylene) has extremely high mechanical strength and toughness, and its wear resistance and impact resistance are among the top in fluoroplastics. It is a ‘high-strength’ fluoroplastic.
Choosing reason: It requires extremely high mechanical strength, impact resistance and wear resistance, while also possessing the basic characteristics of fluoroplastics.

Turning – Milling – Drilling/Tapping – Sawing – Threading – Scraping/Cutting
Features: Easy to process, but with poor dimensional stability. There may be slight rebound or deformation after processing, and stabilization treatment (heat treatment) is required to improve dimensional stability.
Turning – Milling – Drilling – Injection – Molding
Features: PFA is primarily formed through a molding process rather than mechanical processing. Mechanical processing is usually only used for secondary finishing of injection molded parts. PFA has better creep resistance and dimensional stability than PTFE, and the deformation after processing is relatively small.
Thermoforming
Features: One of the most difficult fluoroplastics to machine. Extremely sensitive to heat, prone to internal stress, and may experience stress cracking after processing. It is only recommended to perform mechanical processing when the size cannot be achieved through molding.
Turning – Milling – Drilling/Tapping – Sawing – Stamping
Features: Excellent mechanical processing performance, making it the easiest among the four materials to achieve high precision and good surface quality. However, it is still necessary to pay attention to heat dissipation and use sharp cutting tools.
