Polytetrafluoroethylene pipe and polyethylene pipe, from the name alone, but the polytetrafluoroethylene pipe more than the word four fluorine. However, compared to polyethylene pipe, PTFE pipe has a very significant advantage. So what are the differences between PTFE and polyethylene pipes?
Polytetrafluoroethylene has outstanding excellent comprehensive performance, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, very low coefficient of friction. Used as engineering plastics, can be made into PTFE tubes, rods, strips, plates, films, etc., generally used in high performance requirements of corrosion-resistant pipes, containers, pumps, valves, as well as the system of radar, high-frequency communication equipment, radio equipment, etc..
First of all, the long-term heat-resistant temperature of PTFE pipes can reach as high as 280 degrees Celsius, and can instantly withstand high temperatures of 320 degrees Celsius. While the heat-resistant temperature of polyethylene pipes in 150 degrees Celsius, it has been deformed.
Secondly, the performance of erosion resistance, PTFE pipe also has a significant advantage. Whether it is acid, alkali, reducing agent or oxidizing agent, can not do it; while polyethylene pipe, it will be softened by the oxidizing nature of the acid erosion.
Third, the high flame retardancy of Teflon pipe, it will only be ignited when the oxygen content can reach 95%. This environment is generally not achieved, so it will not burn under normal circumstances, and the fire will be extinguished. Polyethylene pipe, on the other hand, can be ignited at leisure and will spontaneously combust.
