Comparison of consideration factors for the purchase of PTFE rods and analysis of factors affecting the use temperature

- Jan 26, 2019-

A PTFE rod, which is a kind of bar made of PTFE material, is usually PTFE, and this kind of bar has many applications from the current point of view, so it needs a comprehensive understanding and After in-depth understanding, it can be used correctly and reasonably, so as to avoid problems during use.


1. Is there any comparability between the relevant considerations in the purchase of PTFE rod products? What are the requirements for good quality?

In the purchase of PTFE rod products, all relevant factors are taken into consideration, and there is no comparability between these considerations. There are two reasons. First, these are important factors, which are equally important and not important. The second and the second are meaningless and worthwhile, so there is no need to do this work.


If the quality of PTFE rod products is good, it is to meet some conditions and specific requirements. It is to use materials with good quality and performance to ensure the quality of the products and the good performance of the products. In use, do To be simple and convenient, defects are not easy to occur during use, and it is not easy to be damaged or damaged; in terms of service life, the PTFE rod should have a long service life.


2. How should the thermal function and motor of the PTFE rod be correctly understood?

The thermal function of the PTFE rod is correctly understood as follows: between 200 ° C and its melting point temperature, the decomposition rate is very slow and the decomposition amount is very small, and it is not brittle at a low temperature of -250 ° C, so It is used for a long time in the temperature range of -250 °C - 260 °C.

The motor of the PTFE rod is correctly understood because it is a highly non-polar material and has a very good dielectric energy. When the temperature is above 0 °C, the dielectric can be affected by frequency and temperature. It is also not affected by humidity and corrosive substances. Even if it is immersed in water for a long time, it will not change. In the relative humidity of the air, its surface resistivity will not change. In addition, its dielectric strength is independent of cleanliness and has a very low dielectric constant.


3. Does the temperature of the PTFE rod have an influencing factor?

The determination of the temperature of the PTFE rod is mainly based on the use environment, which can reach 150 degrees in the valve industry and 260 degrees in the insulation industry. In addition, the filled PTFE material can reach about 280 degrees in temperature resistance. The two substances, chemical and pressure, sometimes have an effect on the temperature of the PTFE
