PTFE Disk
The PTFE Disk is a polymer Disk in a range of 209 variations split into size, thickness, diameter and other parameters to suit the needs of different scientific and industrial applications. Polytetrafluoroethylene (PTFE) is known for properties such as high thermal stability, low friction and chemical inertness. PTFE's resistance to almost all chemicals means that it's widely used in containers, pipework and machinery. At the same time, its low friction properties are utilized in applications like bearings and conveyor systems. With 209 variations available, our PTFE disks provide the flexibility to select the optimal one for your specific application.
