filled ptfe (Polytetrafluoroethylene, also known as Teflon) is one of the most versatile materials available for seals and other gasket applications. It is essentially inert and can withstand enormous temperature changes without corroding, which makes it an ideal material for use in a wide range of industries.
PTFE is an extremely flexible material and is often susceptible to creep or deformation under heavy loads, however this can be resolved with the addition of a filler. These can include glass, polyamide, carbon, graphite, stainless steel, molybdenum disulfide and bronze, with each providing a specific advantage to the finished product.
The most commonly used filler for PTFE is glass. It can improve dimensional stability, reduce creep and increase wear resistance. It is also effective for high temperatures, making it a good choice for bearing and piston ring applications.
Other fillers such as carbon, graphite, stainless steel and molybdenum disulfide can offer additional performance benefits to the compound if specified in the correct proportions. These can increase compression strength, hardness, abrasion resistance and the coefficient of friction.
Bronze is another common filler and can be added in various percentages to increase abrasion and compressive strength, while still providing the non-stick properties of PTFE. It can also be added to improve the thermal conductivity of the PTFE for applications that require good heat dissipation.
These compounds can be used to produce a range of high temperature seals for applications such as cryogenic valve seats, power transmission assemblies, process ovens and foundry equipment. They can also be used for applications requiring excellent chemical resistance.
