| The properties of PTFE can be modified by adding a range of
fillers. Because PTFE is an inherently soft material making it ideal for
sealing applications, it usually needs reinforcement to enhance the wear and
creep resistance. Chemical inertness and electrical properties are also
affected by fillers.
There are many
fillers used as additives to PTFE. Subsequently there are over 300 different
grades of PTFE Compound available on the market. Many of these have become
industry standards, such as 25% Glass Filled PTFE and many are custom made,
such as 10% carbon fibre + 5% bronze filled PTFE. Please see
Fillers for PTFE for more information. |
