Polytetrafluoroethylene(PTFE)Rod
|
|
Characteristic of the products
There are two types of
PTFE rod. The rod with diameter of 4—9mm is made by paste
extrusion of dispersion polymerized PTFE resin;
There are two kinds of PTFE rods to offer.One is made by ram
extruding method is the diameter form 10~50mm;rods
over the diameter 50mm are manufactured by moulding. |
 |
|
PTFE
has a wide range of practicable temperature from -180℃～+260℃
and a wax-like surface to which anything hardly
sticks.PTFE has the lowest coefficieng of friction of all known
solid materials.It has the best electrical properties of all
plastics. |

|
Use of the products
The electrical insulation used under various kinds of frequency,
the seal liner of various kinds of corrosivity
medium, Antisticking materials, lubriation material.
