INTRODUCTION TO PFA

PFA， the scientific name is perfluoroalkoxy alkane, commonly known as “meltable polytetrafluoroethylene” or “perfluoroplastic”. It inherits almost all the excellent properties of PTFE (polytetrafluoroethylene), while overcoming the disadvantage of PTFE not being melt processed. PFA can be molded through injection molding, extrusion, blow molding, and other processes like traditional plastics, making it a top tier fluoroplastic material for manufacturing high-purity, high-performance, and complex shaped parts.

FEATURES & ADVANTAGES

Feature Description Advantages
Excellent Chemical Resistance Equivalent to PTFE, it is resistant to almost all strong acids, alkalis, organic solvents, and strong oxidants. Capable of handling the most demanding chemical environments, ensuring the long-term stability and purity of products.
Extremely High Temperature Resistance Continuous use temperature is the same as PTFE: -190 ° C to+260 ° C. Can withstand repeated high temperature sterilization (SIP), high temperature processes, and extremely low temperature environments.
Excellent Non Stick & Low Friction Coefficient The surface energy is extremely low, making it difficult to attach any substances and having a low coefficient of friction. Easy to clean, prevents material from hanging on the wall, and ensures efficient fluid transportation.
Extremely High Purity& Low Precipitation It is pure and pollution-free, and it is not easy to precipitate ions and organic matter. It is the preferred material for the semiconductor and biopharmaceutical industries, avoiding contamination of ultra pure chemicals and pharmaceuticals.
Excellent Optical Performance High transparency (visible light transmittance>90%), making it easy to observe internal processes. Suitable for pipelines, mirrors, containers, etc. that require visual monitoring.
Melt Processability This is the fundamental difference from PTFE. Can be processed in a molten state. Capable of manufacturing parts with extremely complex shapes (such as threaded three-way valve bodies) and achieving seamless welding.

MAterial limitation

  • High cost: It is one of the most expensive types of fluoroplastics.
  • Mechanical strength is average: although better than PTFE, it still has a certain degree of cold flow (creep) and is not suitable for withstanding high loads.
  • Breathability: Has a certain degree of permeability to gases.
