P.T.F.E.
(Polytetrafluroethylene), an insert, non-toxic material is well known for its properties such as virtual immunity to chemical or solvent attack. Therefore, it is the best-suited material for bushes, seals etc. for revolving shaft applications under the most corrosive acid, alkali or solvent service conditions.
|
|
|
|
Some of the other important properties are:-
|
|
A. Chemical Resistance:
|
| 1. |
P.T.F.E. is not affected by any known solvents. |
| 2. |
Water absorption in Nil |
| 3. |
No common acid or base is absorbed by
P.T.F.E. at temperature upto 250oC
(480oF) |
| 4. |
Non-toxic, non ageing, non wet, light and stable and Hygienically clean. |
|
|
|
|
B. Electrical Properties:
|
| 1. |
Hi dielectric strength |
| 2. |
Low dielectric constant –
P.T.F.E. does not alter with frequently or temperature. |
| 3. |
Heat resistant – No risk of insulation failure due to moisture |
|
|
|
|
C. Thermal Properties:
|
| 1. |
Wide temperature range:
-80oC to 250oC |
| 2. |
Unaffected by weathering. |
| 3. |
Does not burn or smoke |
| 4. |
Enable deep freezing |
| 5. |
Not affected by ultraviolet rays |
|
|
|
|
D. Mechanical Resistance:
|
| 1. |
Excellent abrasion resistance |
| 2. |
Low coefficient of friction (0.05-0.08) |
| 3. |
Self lubrication. Specific gravity – 2.14 to 2.20 |
| 4. |
Excellent machinability to close tolerances |
| 5. |
Tough and flexible even at low temperature |
| 6. |
P.T.F.E can be machined easily by means of normal matching operations such as turning, milling and drilling etc. |
