PTFE GENERAL FEATURES |
|
Heat |
Flame Resistance |
Friction and Wear |
When PTFE almost all plastics and elastomers exposed to a
temperature beyond the heat-Limit even a material which retains
features.
Depending on the end-use criteria, PTFE continuous service
temperature is 260 0C. Short term can withstand higher
temperatures in use. |
PTFE excellent high temperature and flame resistance and high
melt has a failure temperature. Flame propagation
characteristics such as PTFE produce heat release and fire rate
is quite low. |
Coefficient of friction of PTFE solid material is a material
which is the lowest. Abrasion resistance fiber glass fibers, can
be made using carbon or graphite on the intended use. |
|
Environment Pollution |
Bonding, Separation |
Working in Low Temperature |
|
PTFE is chemically pure and inaktifd. Oil, stabilizing additives,
plastics additives or does not contain additives such as process
fluid from polluting antiokisi. |
PTFE has extremely low surface energy in the solid state. This
feature provides an excellent non-sticky and wet environment. |
Even at temperatures well below minus temperatures PTFE
maintains excellent properties. PTFE impact resistance at low
temperatures exceeds the impact resistance of most other
polymers |
|
Corrosion |
Service Life |
Light Stability |
|
PTFE has excellent chemical resistance. In a wide temperature
range PTFE most severe organic and inorganic chemicals,
resistant to acid and the solution. |
PTFE oils, solvents, UV light, oxidizing agents, other
environmental agents and retains its properties even at high
temperature in an excellent manner. Color change and are
resistant to brittle fragility |
PTFE has the lowest refractive index.
When exposed to ultraviolet and infrared light it does not
change the appearance. |
|
Dielectric |
Biodegradability |
Humidity |
|
PTFE dielectric strength is very good and has a
dielectric constant. The loss factor is low. In terms of
stability and level of dielectric property in a wide
environmental conditions it is better than most of PTFE
material. |
PTFE pure form, the space for the microorganisms and nutrients
are inactive against microbial proliferation and provide an
environment where enzymes attack. |
PTFE is completely resistant to chemical reactions. It is a good
barrier against water. Even though the long-term water PTFE
chemical, physical and dimensional characteristics remain the
same unchanged. |
