What are the types of fluoroplastics?

"Teflon" is the common name for polytetrafluoroethylene (PTFE). In a broader sense, the term encompasses a variety of fluoroplastic materials. The key differences are as follows:

Polytetrafluoroethylene (PTFE)
Temperature range: -196°C to 260°C
Characteristics: Exceptional chemical stability—virtually insoluble in any solvent—with an extremely low coefficient of friction. It is fire-resistant, non-stick, and corrosion-resistant.

Fluorinated Ethylene Propylene (FEP)
Temperature range: 200°C
Characteristics: Excellent insulating properties. It is frequently used in applications such as battery monitoring cables for new energy vehicles, offering a lifespan three times longer than standard PVC in salt-spray environments.

Perfluoroalkoxy (PFA)
Temperature range: Above 260°C
Characteristics: High toughness; suitable for long-term use in high-temperature environments, such as in wiring for ovens and other home appliances.

Polyvinylidene Fluoride (PVDF)
Temperature range: 150°C
Characteristics: Suitable for high-temperature environments, such as steam heating systems.

Fluorinated Ethylene Propylene (FEP)
Temperature range: 200°C
Characteristics: Similar to FEP (as noted above), though specific application scenarios may vary.
