PTFE
Rod is often chosen to produce bearings because of its very low
friction and also for its free running ability. Because of its ability
to conform to shape otherwise known as flow, PTFE Rod is used for seals
in valves, this is because it can conform to shape and create a high
specification valve seal. PTFE Rod can easily be machined but due to the
surface softness, care must be taken in lathe jaws or high compressive
loads, which may cause distortion. Another important element to remember
regarding PTFE Rod is the coefficient of expansion due to heat changes;
this can be uneven with PTFE and may cause distortion in components.
PTFE Rod have some excellent properties of enduring
chemeistry&corrosiveness, dielectric, non-ageing, airproof, hight
lubricity and has a wide range of practicable temperature from
-180-+250° C and a wax-like surface where anything hardly sticks on and
the lowest coefficient of friction of all known solid materials.
Application
PTFE molded rod is use of the products the electrical insulation used under various kinds of frequency, the sesal liner of various kinds of corrosivity medium, antisticking materials, lubriation material.
