PFA tubing is a tubing made of perfluoroalkoxy resin that is chemically inert and resistant to high temperatures. It can maintain stability in extreme environments, has high transparency, and good flexibility, and is suitable for making corrosion-resistant fluid transportation pipelines, wire and cable insulation, and chemical equipment parts, etc., and is widely used in semiconductor, aerospace and pharmaceutical industries.
FEP tubes are also made of fluoroplastic material, the main component of which is fluorinated ethylene propylene copolymer. Triflinite FEP tubing has excellent chemical resistance, non-stick, and electrical insulation properties, and is stable over a wide range of temperatures. It is commonly used in applications that require a high degree of corrosion resistance and clean environments, such as conveyor lines, laboratory equipment, and wire and cable jackets in the chemical industry.
Distinguishing PFA tubing from FEP tubing is typically based on their physical properties and application performance
1.Appearance & Transparency: While both have some transparency, PFA tubing tends to be more transparent and visually clearer than FEP tubing.
2.Mechanical properties: Compared with FEP tubing, PFA tubing may be slightly better in hardness and wear resistance, showing better creep resistance.
3.Temperature resistance: The upper limit of the long-term use temperature of PFA tube is generally higher than that of FEP tube, the melting point range of PFA is 295 310 °C, while the melting point range of FEP tube is mostly between 250 and 270.
4.Processing characteristics: PFA has more stringent requirements for process conditions during the molding process, such as the need to control the mold temperature to reduce internal stress, and avoid color change or bubble formation caused by excessive molding temperature; FEP tubes also need to pay attention to temperature control during processing, but their processing window is relatively wide.
5.Practical application test: The two can be further distinguished by tests of tensile strength, elongation at break, solvent resistance, etc.
