Main differences between PFA and PTFE tubes

1. PFA transparent tube

The natural color of PFA pipe is transparent color, because the pipe processed from PFA resin raw materials has high transparency, sometimes called PFA transparent pipe.

PFA pipe is through the PFA resin raw material extrusion molding, injection molding of the pipe, in general, we are talking about extrusion molding of the pipe. It has excellent heat resistance, chemical resistance and electrical properties, and can be formed by various melting resin forming methods. Excellent heat resistance (mechanical strength maintained in a wide range of temperatures from -80 ° C to 260 ° C), excellent chemical resistance (almost inert to all chemicals);

• Excellent electrical characteristics (low dielectric constant and low dielectric loss factor at high frequencies, insulation);

• Excellent flame retardancy (limiting oxygen index 95Vol%, UL94V-0).

2. PTFE pipe (Teflon PTFE pipe)

Polytetrafluoroethylene pipe is the use of high-quality plunger extrusion pipe (paste extrusion and powder extrusion 2 processes), the use of special processing technology. Polytetrafluoroethylene (PTFE) has excellent chemical stability, capable of all strong acids, strong bases, strong oxidants, and a variety of organic solvents do not react. PTFE is used in a wide temperature range

3. The main difference between PFA tube and PTFE tube

• PTFE is also called polytetrafluoroethylene: ordinary PTFE pipes are white and opaque, mainly pipes, hoses, pipe lining pipes, braided reinforced pipes and so on.

• PTFE pipe has excellent temperature resistance and superior chemical resistance, can transmit the temperature of up to 260℃ liquid or gas, and high chemical purity, more suitable for a wide range of continuous operating temperature requirements.

• PTFE tubes rely on their excellent electrical properties also make it a more suitable material for electronics and electrical fields, mainly used in electrical insulation sheath, chemical transport, heat communicator, medical urinary catheter and surgical vascular bypass. PFA is also called tetrafluoroethylene: the physical, electrical and chemical properties of PFA tubes are similar to polytetrafluoroethylene.
