PTFE (Polytetrafluoroethylene) is perhaps the most widely used fluoropolymer available. Originally trademarked by Dupont under the trade name TEFLON®, PTFE has many features which make it ideal for a wide range of applications.
PTFE tubing is more flexible than all other tubing in its class, and can resist nearly all industrial chemicals. Also, with a temperature range of approximately -330 to 500 °F, it offers the widest temperature range of the fluoropolymers. In addition, it has excellent electrical properties and low permeablility.
PTFE tubing is most widely used as laboratory tubing and for applications where chemical resistance is important. PTFE has a very low coefficient of friction and is one of the most “slippery” substances known.
