PFA TUBE

Specifications (PFA TUBES)

PFA (Polytetrafluoro ethylene), also known as  soluble PTFE, is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene.

    While retaining most advantages of PTFE, PFA can be hot-melt processed due to the decrease of crystallinity, melting point and melt viscosity.

    Comparing to FEP, PFA is superior in terms of high temperature resistance and stress crack resistance. Comparing to PTFE, PFA has excellent folding resistance, and a superior mechanical strength at high temperature than PTFE.

    PFA has high and low temperature resistance, long-term use temperature is within -200  °  C  ~  260  °  C.  It  has  excellent  corrosion  resistance  to  all  chemicals. Moreover, its friction coefficient is low.

    PFA has  good  electrical properties.  Its  electrical  insulation  is not  affected by  temperature;  its  dielectric  properties  are  good;  and  its  radiation  resistance  is excellent. In addition, the flame retardancy reaches V0 level.

   Our  PFA  Tube  is  made  of  imported  PFA  resin,  which  has  excellent  chemical resistance, high temperature resistance, fine crack resistance, and good transparency. In comparison to other fluoropolymer tubes, PFA has higher polymerization purity and continuous working temperature. It is ideal for critical low-voltage applications.
