What are the differences between PTFE, PCTFE (Daiflon), and Nylon 66?
A comprehensive guide on how to choose resin gaskets for high-pressure gas and chemical-resistant lines!
In selecting sealing materials (such as resin gaskets and valve seats) for harsh environments like high-pressure gas piping and chemical lines, we often hear concerns like, "I don't really understand the difference between PTFE and PCTFE," or "I'm using PTFE fluoropolymer packing in a high-pressure environment, but it's becoming deformed and causing leaks." In facilities that handle industrial gases (such as oxygen, nitrogen, argon) or special chemicals, general-purpose rubber and plastics cannot be used. Mistakes in material selection can directly lead to equipment downtime or serious issues, so it is crucial to correctly understand the properties of engineering plastics and to use materials like valve seat materials appropriately for their intended applications. *For more details on the column, you can view it through the related links.
