There are two types of PTFE rods. The rod with diameter of 4 - 9mm is made by paste extrusion of dispersion polymerized PTFE resin; the rod with diameter of 10 - 50mm is made by ram extruding method, and rods over the diameter 50mm are manufactured by molding.

PTFE has a wide range of practicable temperature from -180 ~ 260°C and a wax-like surface to which anything hardly sticks. PTFE has the lowest coefficient of friction of all known solid materials. It has the best electrical properties of all plastics.
