What do PTFE fillers and flexible graphite refer to respectively? What other differences are there?
This post was last edited by 19751107w on 2010-11-5 at 16:30. PTFE is polytetrafluoroethylene; the main differences between the two lie in their areas of use and operating temperatures. PTFE generally cannot be used at temperatures above 180 degrees, and in practice we usually use it up to around 150 degrees! The operating temperature for flexible graphite is much higher; it can generally reach 450 degrees or even higher! It mainly depends on the material of the reinforcing substance. Furthermore, in applications such as the pharmaceutical industry and domestic water supply where cleanliness of the medium is required, graphite gaskets or graphite packing are generally not used. The above is just a brief overview; I hope it will be useful to you
