Introduction
Perfluoroalkoxy alkane (PFA) is a high-performance, melt-processable fluoropolymer that represents the pinnacle of fluoropolymer technology for many demanding applications. Sharing the exceptional chemical inertness and thermal stability of PTFE, PFA surpasses it in one critical area: continuous service temperature. PFA can withstand continuous use at temperatures up to approximately 260°C (500°F), making it ideal for the most extreme thermal and chemical environments. Additionally, like FEP, PFA is fully melt-processable, allowing for complex extrusion, injection molding, and blow molding. These superior properties position PFA resin and semi-finished products as the material of choice for ultra-high purity, high-temperature, and highly corrosive applications. This article explores the key properties of PFA and its critical role in the most demanding industrial sectors.
Core Properties of PFA
- Extreme Thermal Stability: Highest continuous use temperature among melt-processable fluoropolymers (up to 260°C).
- Unmatched Chemical Resistance: Virtually inert to all chemicals, including highly reactive substances.
- Total Transparency: Optically clear, allowing for visual monitoring in critical processes.
- Superior Electrical Properties: Excellent dielectric strength and low dissipation factor across a wide frequency range.
- Melt-Processability: Fully processable via extrusion, injection molding, and rotational molding.
- Low Extractables/High Purity: Minimal impurities leaching out, essential for semiconductor and pharmaceutical applications.
- Flame Retardancy: Self-extinguishing (UL 94 V-0 rating achievable).
- Mechanical Toughness: Better mechanical properties than PTFE, especially at low temperatures.
