Why polytetrafluoroethylene rubber joints are widely used

Polytetrafluoroethylene (abbreviated as PTFE), commonly known as "Plastic King", is a polymer made of tetrafluoroethylene. It is white wax, semi-transparent, heat-resistant, cold-resistant, and can be used for a long time from -180 to 260ºC. This material is resistant to acid, alkali and various organic solvents, and is insoluble in almost all solvents. At the same time, PTFE has the characteristics of high temperature resistance and very low coefficient of friction, so it can not only lubricate, but also become the ideal coating for easy cleaning of the inner layer of water pipes.
Lined with PTFE (on the basis of natural rubber spheres or EPDM rubber spheres, the inner wall lined with PTFE can achieve the effect of resistance to strong acids and alkalis, compared with fluorine rubber spheres, reducing the cost of use); stainless steel conduit (in order to achieve the effect of negative pressure resistance, resistance to particulate media, the conduit is placed inside the sphere) flange part: national standard Q carbon steel flange 235 (low cost, mature technology, application wide range.
The above is a small series of search Baidu encyclopedia, to get the academic answer! Although it is not easy to understand, it is not difficult to find that PTFE is resistant to high temperature, oil, acid and alkali environments, and can withstand almost all harsh environments.
The application of rubber joints is generally used to cover pipelines in various industries, so the environment of use varies greatly, and there may be various harsh environments. For example, the concentration of acid and alkali in the medium in the pipeline is very high, the temperature of the pipeline is also very high, and there is a large amount of granular material in the medium. At this time we choose ordinary oil, temperature or wear resistant rubber joints, which simply can not meet this pipeline environment. The appearance of PTFE solves these problems. Jiankun Water Supply Equipment Factory designed the rubber soft joint lined with PTFE and required this joint to be able to be installed closely on the pipeline. Rubber transformer also did a lot of experiments.
If we don't choose the right pipe connector when we use it, it's not only a waste of time, but the damage caused by the need to stop production for every pipe maintenance is unpredictable! ~ So it is very important to choose the right product.
