what is PFA tubing

What is PFA tubing


PFA tubes - soluble polytetrafluoroethylene tubes, transparent Teflon tubes, PFA transparent tubes.



Characteristics: Tetrafluoroethylene and perfluoropropyl vinyl ether copolymer, also known as soluble polytetrafluoroethylene, fully maintains the excellent performance of polytetrafluoroethylene, with a usage temperature of -200~250 ℃, good mechanical and electrical insulation performance, outstanding heat resistance, low friction coefficient, flame resistance, low smoke, and weather resistance. At the same time, it has good thermoplastic properties.



Utilization characteristics:


1) Corrosion resistance; Only the elements fluorine and alkali metals react with it at high temperatures, and have no effect on all other concentrated and dilute inorganic organic acids, bases, and esters.

2) High and low temperature resistance: -200 to+260 ℃, with high temperature strength twice that of F4, non sticky, suitable for mixing water and oil; There is no fouling or stagnant flow inside and outside the pipe wall.

3) High transparency: Among all plastics, the refractive index of light is the lowest. Appearance: The inner and outer walls of the pipe are smooth, flat, and clean; The color is transparent, semi transparent, or milky white (determined by wall thickness)

4) Weathering resistance: Can be exposed to ozone sunlight for a long time.

5) Easy for secondary processing: self sealing, self welding, flanging, and disc oriented tube making.
