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.
Let's take a look at the characteristics of PTFE pipe. It is a white opaque pipe with many forms, including pipes, hoses, pipe lining pipes, braided reinforced pipes, etc. After testing, PTFE tube has excellent high and low temperature resistance and chemical resistance, and can transport liquids or gases with temperatures up to 260°C.
The PFA tube is made of a melt-processable thermoplastic. Although it also has excellent stress cracking resistance and bending life, it is obviously inferior to the PTFE tube in terms of permeability. Because the content of metal ions in the PFA tube is very low, it can also maintain strong strength and burst pressure at higher temperatures.
It is precisely because the PTFE tube has excellent electrical properties, so it has become a suitable material in the field of electronics and electrical engineering, mainly used for electrical insulation sheath, chemical transportation, heat exchanger, chemical heavy corrosion and so on. The PFA tube can be used to make a variety of specifications of the digestion tube
The appearance of PFA digestion tube is translucent, and it also has many excellent properties, such as high and low temperature resistance, corrosion resistance, insulation resistance, pollution prevention and so on. The appearance is translucent. Due to the extremely low dissolution and precipitation of PFA materials, it can be an ideal choice for storing standard substances and strong corrosive substances;
It seems that both PFA tube and PTFE tube have their own unique properties, prompting them to play a role in various fields. The application of the two is not in conflict and can even make up for each other.
