Polytetrafluoroethylene(PTFE)rod

[ Features ]
There are two kinds of PTFE rods to offer. One is manufactured by Paste extruding method in the diameter from 4 to 9mmand the other Is made by ram extruding method is the diameter from 10to 50mm;rods Over the diameter 50mm are manufactured by moulding. PTFE is the most chemical-resistant of all known plastics. It does not age.
PTFE has a wide range of practicable temperature from-180+260and 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.
