This lubricating effect is due to PTFE's very low surface friction (one of the lowest friction coefficients, in fact, of any known solid).Proper application of PTFE tape, therefore, can allow the threads on a pipe joint to be mated more tightly together, and in most cases should prevent them from seizing up if you need to unscrew them at any point in future.about our factory: Taixing City Hongde Electric Co., Ltd. was founded in 2012.
