Teflon PFA tube performance advantages
Teflon PFA tube has excellent chemical stability, mechanical properties, electrical insulation, self-lubricating, non-sticky, non-flammable and aging resistance. Its outstanding feature is that the melt viscosity is much lower than that of PTFE, so it can be processed by ordinary thermoplastic forming methods. Its products have good high temperature stability, high temperature mechanical strength is about 2 times that of PTFE, PFA film is softer than PTFE, with good bending and cracking resistance.

The main difference between PFA tube and PTFE tube is performance and use
There is no obvious difference between PFA tube and PTFE tube from the outside, and the main difference may be reflected in the performance, so the actual use of PFA tube and PTFE tube is also different. But what exactly needs further analysis.

Teflon tube factory
There are at least hundreds of Teflon pipe factories in the country, but there are many kinds of Teflon pipes, and the production of each manufacturer is also different. Teflon tubes have Teflon capillaries 30L-0L and some T-type S-type tubes are mainly used for transformers, and Teflon tubes are medium-wall tubes, and the main specifications are 2*4 4*6 6*8*10 10*12 12*14... There is also a Teflon tube, which mainly produces some large-size and thick-walled tubes, including 30*40 60*80*90*110 and so on.

The difference between white and transparent Teflon tube
Ptfe heat shrinkable tube requires that the inner diameter after heat shrinkage is less than 0.2mm and the outer diameter is not more than 0.35mm. First, the heat shrinkable tube is made of pfte, fep and pfa. Second, the heat shrinkable tube has production specifications. The minimum inner diameter is 1mm ~ 150mm and the minimum thickness is 0.1mm ~ 0.5mm.

The difference between polytetrafluoroethylene and polyethylene
Polytetrafluoroethylene [PTFE,F4] is one of the best corrosion resistance materials in the world, so it is known as the "plastic king. Polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE, and the trade name is "Teflon". The basic structure of PTFE is:-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-CF2-.

What material is Teflon?
When we studied chemistry, we all learned polytetrafluoroethylene, molecular formula: C2F4, tetrafluoroethylene is mainly made of chloroform, but also by tetrafluorodichloroethane in the presence of chlorine trifluoride catalytic dechlorination. It is a colorless and odorless gas at normal temperature, with a boiling point of -76.3 ℃, which can be liquefied under pressure, with a critical temperature of 33.3 ℃ and a critical pressure of 3.92MPa.
