The properties of the carbon-fluorine bond, together with high molecular weight, endow Teflon with a set of exceptional properties:
- Temperature range:-200ºC a + 250ºC
- Resistance to most chemical products, only fluorine derivatives, fluorine itself and fused alkaline metals are able to attack Teflon.
- Low coefficient of friction.
- Anti-adherent
- Inflammable.
- Excellent dielectric properties
- Good mechanical properties
- Resistant to ageing
- Non-toxic
- Aseptic, does not contaminable the fluid.
Gaskets manufactured using this material is employed in a wide range of applications due to this inert condition and cleanliness: the food industry, drinking water, the pharmaceutical, electrical, agricultural and construction industries etc.
In function of use, the material (PTFE) may be combined with graphite, glass or bronze etc, which improves its mechanical strength.
Sandwich gasketsFlat gasketsSpecial gaskets
Gaskets consisting of an outer PTFE coating over a core of soft or plastic material, together with the possibility of also including a corrugated metal inside.
This gasket is especially recommended for applications with aggressive fluids where, in addition to the resistance provided by a pore-free material such as PTFE, flexibility is also required, and which is provided by the filling.
They can be manufactured according to standards or flat.
Gaskets which may be manufactured in any size or shape, whether standard or flat. They are recommended for use with chemicals substances, as electrical insulators or for fluids that require a non-contaminating seal, such as in the food industry.
Teflon gaskets can be employed in applications that require excellent etc. – chemical resistance. Together with good coefficient of friction, such a valves, pumps and machinery, etc.
This material is suitable for machining for the production of O-rings, pressure gaskets, washers and bushing etc.
