If your temperature requirements are up to 260�°C (500�°F), PTFE tubes (polytetrafluoroethylene) are recommended. When terminated, it can be prevented from "melting" by soldering iron. Due to its excellent dielectric properties, it is widely used in electronic and electrical services. Another major advantage of PTFE tubes is their non-stick properties, allowing the material to be transported with minimal fluid resistance. Note, however, that PTFE reacts with fluorine, molten sodium hydroxide, and molten alkali metals. We have a full range of PTFE extrusion tubes for protecting wiring or transporting fluids in critical applications. PTFE tubes are available in a variety of configurations and custom designs. PTFE tubes have inherently excellent chemical resistivity and low coefficient of friction, and their performance is superior to that of glass and graphite, making them ideal materials for fluid transport. PTFE tubes can be used with almost all industrial solvents, chemicals and corrosive materials, and can be used in high-temperature processes. It can be steam sterilized without affecting its physical properties, such as surface hardness, elongation, deflection life or load deformation. PTFE tubes are usually translucent white, however, the whiteness varies depending on batch and wall thickness size. Colored PTFE tubes are also available and are often used to simplify tube wiring during system installation.
