Some of the widely accepted applications of PTFE rods are:
The most widely available sizes (in diameter) are 0.062" to 9.000". However, the custom sizes are designed and made on special request of the customers. OPERATING TEMPERATURES The PTFE rods maintain a high viscosity at 327 °C. However, PTFE can operate between -200 °C to +260 °C.
